vibro acoustic analysis procedures for the evaluation of the sound insulation characteristics of Agricultural Machinery cabins
Journal of Sound and Vibration, 2003Co-Authors: Wim Desmet, Bert Pluymers, Paul SasAbstract:Abstract Over the last few years, customer demands regarding acoustic performance, along with the tightening of legal regulations on noise emission levels and human exposure to noise, have made the noise and vibration properties into important design criteria for Agricultural Machinery cabins. In this framework, both experimental analysis procedures for prototype testing as well as reliable numerical prediction tools for early design assessment are compulsory for an efficient optimization of the cabin noise and vibration comfort. This paper discusses several numerical approaches, which are based on the finite element and boundary element method, in terms of their practical use for airborne sound insulation predictions. To illustrate the efficiency and reliability of the various vibro-acoustic analysis procedures, the numerical procedures are applied for the case of a harvester driver's cabin and validated with experimental results.

vibro acoustic analysis procedures for the evaluation of the sound insulation characteristics of Agricultural Machinery cabins
Proceedings of SPIE the International Society for Optical Engineering, 2001Co-Authors: Wim Desmet, Bert Pluymers, Paul SasAbstract:Over the last few years, customer demands regarding acoustic performance, along with the tightening of legal regulations on noise emission levels and human exposure to noise, have made the noise and vibration properties into important design criteria for Agricultural Machinery cabins. In this framework, both experimental analysis procedures for prototype testing as well as reliable numerical prediction tools for early design assessment are compulsory for an efficient optimisation of the cabin noise and vibration comfort. This paper describes an experimental procedure for the in-situ assessment of the air-borne sound insulation characteristics of a cabin using a two-microphone sound intensity probe. In addition, several numerical approaches, which are based on the finite-element and boundary element method, are discussed in terms of their practical use for air-borne sound insulation predictions. To illustrate the efficiency and reliability of the various vibro-acoustic analysis procedures, all experimental and numerical procedures are applied and evaluated for the case of a cabin scale model.

lean production market share and value creation in the Agricultural Machinery sector in brazil
Journal of Manufacturing Technology Management, 2010Co-Authors: Paul Forrester, Ullisses Shimizu, Horacio Sorianomeier, Jose Arturo Garzareyes, Leonardo Fernando Cruz BassoAbstract:Purpose – The “resource‐based view” (RBV) of firms considers that major operational and organisational advantages are created in the internal environment of a firm. The implementation of lean manufacturing represents the potential for strategic advantage over competitors, especially in craft‐based industries in developing regions of the world. The purpose of this paper is to investigate the relationship between the adoption of lean manufacturing and market share and value creation of companies in the Agricultural Machinery and implements sector in Brazil.Design/methodology/approach – The paper is based on data collected in a survey conducted across 37 firms in the Agricultural Machinery and implements industry in Brazil. The data were used within a model for assessing the degree of leanness to test three hypotheses using correlation, regression, analysis of variance and cluster statistical methods.Findings – Brazilian firms and managers in this sector that have supported a transition towards the adoption ...

lean production market share and value creation in the Agricultural Machinery sector in brazil
Journal of Manufacturing Technology Management, 2010Co-Authors: Paul Forrester, Horacio Sorianomeier, Jose Arturo Garzareyes, Ullisses Kazumi Shimizu, Leonardo Fernando Cruz BassoAbstract:By adopting Lean Manufacturing firms wants to see the value created in its results at the bottom line. The Agricultural Machinery and implements sector in Brazil had experienced in Lean and saw its results affected by the program. Using an established analytical model, the paper tests three hypotheses: H1: firms with a high degree of management commitment to the program simultaneously support this commitment with investments in support of the plant infrastructure and problem-solving groups; H2: firms that adopt lean principles have made changes in the direction of these principles; H3: firms that made continuous investments in plant infrastructure in to support lean principles have better performances. All hypotheses H1, H2 and H3 were fully accepted and corroborated.

comprehension rates of safety pictorials affixed to Agricultural Machinery among pennsylvania rural population
Safety Science, 2018Co-Authors: Federica Caffaro, Susanna Schmidt, Dennis J Murphy, Eugenio CavalloAbstract:Abstract Pictorials affixed to Agricultural Machinery are important tools to warn the user about the risks that can arise from the intended use or any foreseeable misuse of the machine; however, in the U.S. there is no legal requirement regarding the adoption of safety pictorials on Agricultural Machinery. This study investigated comprehension of safety pictorials in a sample of U.S. Agricultural Machinery users. Two hundred and eight Pennsylvanian participants were asked to indicate the meaning of 12 frequent safety pictorials by choosing one among 4 alternative labels. The results showed that pictorials referring to the most common risks in agriculture were not necessarily the best comprehended images, and two out of five participants have never seen the pictorials included in the study. Years of experience with the Machinery enhanced comprehension, whereas ‘part-time’ farming and occasional use of Machinery were related to poorer comprehension. Implications for operators’ safety and solutions to improve pictorial noticeability and comprehension are discussed.

safety signs on Agricultural Machinery pictorials do not always successfully convey their messages to target users
Applied Ergonomics, 2017Co-Authors: Federica Caffaro, Alberto Mirisola, Eugenio CavalloAbstract:This study investigated the extent to which a sample of Italian users comprehended safety pictorials used on Agricultural Machinery. A questionnaire with 12 safety pictorials was administered to 248 users of Agricultural Machinery. For each of the pictorials, the participants were asked to select the most appropriate description of four written choices. The investigated safety pictorials were, in general, not well comprehended. Two different classes of participants were identified, each with a different level of comprehension. The participants with better comprehension were characterized by the regular use of Agricultural Machinery and frequent previous exposure to pictorials. The need for training courses focusing on safety pictorials and their meanings, as well as the need for improvement to the pictorials themselves to make them more easily comprehended, is discussed.

part time farmers and accidents with Agricultural Machinery a moderated mediated model on the role played by frequency of use and unsafe beliefs
Journal of Occupational Health, 2017Co-Authors: Federica Caffaro, Michele Roccato, Margherita Micheletti Cremasco, Eugenio CavalloAbstract:OBJECTIVES We aimed at testing a model of the direct and indirect effects of being a part-time farmer on the probability of being involved in an Agricultural Machinery-related accident, considering the role played by unsafe beliefs and the frequency of use of Machinery. METHODS Two-hundred and fifty-two Italian men, regular users of Agricultural Machinery (age: Mean = 45.1 years, standard Deviation = 17.5), were administered a paper-and-pencil questionnaire addressing their relation with work, unsafe beliefs, and previous experience of Machinery-related accidents. RESULTS Being a part-time farmer showed a positive association with unsafe beliefs only among occasional Machinery users. Unsafe beliefs in turn showed a positive association with accidents. CONCLUSIONS The study gave a novel contribution to the knowledge of the chain of events connecting part-time farmers with Machinery-related accidents. Preventive training interventions targeting part-timer farmers using Agricultural Machinery just occasionally should be developed.

Comprehension of safety pictograms affixed to Agricultural Machinery: a survey of users
Journal of Safety Research, 2015Co-Authors: Federica Caffaro, Eugenio CavalloAbstract:INTRODUCTION: Pictograms affixed to Agricultural Machinery are important tools to reduce the occurrence of accidents and injuries when correctly noticed, comprehended, and followed. This study investigated the knowledge of safety pictograms used in Agricultural Machinery in a sample of farmers and farm workers and examined the factors influencing their comprehension. METHOD: A questionnaire with 12 safety pictograms used for Agricultural Machinery was administered to 281 owners or users of Agricultural Machinery. For each of the pictograms, the participants had to select the most appropriate verbal description from among four choices. RESULTS: The pictograms examined yielded poor comprehension scores, including warnings related to the most frequent accidents involving Agricultural Machinery. Familiarity with the pictograms and years of experience with Agricultural Machinery significantly increased users' comprehension of the meaning of the pictograms. CONCLUSIONS: Specific training programs should be designed to draw attention to safety pictograms and to instill their meaning. Language: en
