  • a neural network based diagnostic test system for armored vehicle Shock Absorbers
    Expert Systems With Applications, 1996
    Co-Authors: Patrick J Sincebaugh, William H Green, Gerard J Rinkus
    Abstract:

    Abstract In this paper we describe the development of a neural network based diagnostic system that is being utilized to evaluate the condition of armored vehicle Shock Absorbers. We begin by providing the motivation behind the development of the Smart Shock Absorber Test Stand (SSATS). We then describe the theory required to evaluate the condition of Shock Absorbers. This theoretical discussion leads to a description of the type of data that are acquired during a Shock absorber test and how it can be analyzed to determine the condition of a Shock absorber. The next section describes how the data are transformed and processed in order to develop a neural network classification scheme. The training and testing process of a fully connected feedforward backpropagation neural network is then described. Finally, we explain the integration of the neural network into the SSATS system and the results of utilizing the system to test Bradley Armored Vehicle Shock Absorbers.

  • Experimental study on impact behaviors of rubber Shock Absorbers
    Construction and Building Materials, 2018
    Co-Authors: Xiao-hong Long, Rong Yue, Jian Fan
    Abstract:

    Abstract In the seismic design of continuous girder bridges, rubber Shock Absorbers set between the girders and between the girders and the abutments could reduce the magnitude of impact behaviors and mitigate the damage incurred by structural collisions effectively. However, in practice, rubber Shock Absorbers are only considered as a construction measure, and the current research on the impact mechanical properties of rubber Shock Absorbers is very limited. In this paper, two types of rubber Shock Absorbers: natural rubber Shock Absorbers (N-RSA) and high-damping rubber Shock Absorbers (HD-RSA) were selected for study. Shape factor, volume, and shape (square vs round shapes) were proposed as controlling variables for the design of multiple sets of rubber Shock Absorbers. We also studied the impact of various factors on the force-displacement of rubber Shock Absorbers under the application of static loading. Using self-designed pendulum impact equipment, this research investigated the impact of pendulum impact velocity, the shape factor, volume, and shape of the rubber Shock absorber on the force-displacement of the Shock absorber. The results of this work may provide reference for the establishment of a nonlinear impacting mechanical model of a rubber Shock absorber and the seismic design and analysis of bridge structure.

  • optimized design and characterization of motor pump unit for energy regenerative Shock Absorbers
    Applied Energy, 2018
    Co-Authors: Renato Galluzzi, Nicola Amati, Andrea Tonoli
    Abstract:

    Abstract The constant need to reduce emissions in the automotive sector has driven the electrification of powertrain and chassis. To comply with this trend and decrease the bound even further, the present paper proposes the use of hydraulic regenerative Shock Absorbers for automotive suspension systems. The conversion of linear into angular motion and the suitable control of an integrated electric machine allow to transform part of the vibrational energy into electricity. In these damping devices, the key element is the motor-pump unit that is interfaced onto a conventional hydraulic cylinder architecture. Hence, the proposed research focuses on this component by investigating different design aspects in all the domains of interest. The objective is to optimize the energy conversion efficiency of the unit without affecting its damping control property. To give means of validation, a motor-pump prototype is built and experimentally characterized through a dedicated test rig.

  • modeling control and validation of electrohydrostatic Shock Absorbers
    Journal of Vibration and Acoustics, 2015
    Co-Authors: Renato Galluzzi, Andrea Tonoli, Nicola Amati
    Abstract:

    The implementation of variable damping systems to increase the adaptability of mechanical structures to their working environment has been gaining increasing scientific interest, and numerous attempts have been devoted to address vibration control by means of active and semi-active devices. Although research results seem promising in some cases, the proposed solutions are often not able to fulfill requirements in terms of compactness and simplicity on one hand, and dynamic performance on the other. In this context, the present paper discusses the modeling and control of an electrohydrostatic actuation (EHA) system for its implementation as a damping device. A model of the device is proposed and analyzed for design purposes. Subsequently, a damping control strategy is presented. Finally, a case study introduces and validates an EHA prototype for helicopter rotor blade lead-lag damping.

  • modelling and validation of electromechanical Shock Absorbers
    Vehicle System Dynamics, 2013
    Co-Authors: Andrea Tonoli, Nicola Amati, Renato Galluzzi, Joaquim Girardello Detoni, Enrico Gasparin
    Abstract:

    Electromechanical vehicle suspension systems represent a promising substitute to conventional hydraulic solutions. However, the design of electromechanical devices that are able to supply high damping forces without exceeding geometric dimension and mass constraints is a difficult task. All these challenges meet in off-road vehicle suspension systems, where the power density of the dampers is a crucial parameter. In this context, the present paper outlines a particular Shock absorber configuration where a suitable electric machine and a transmission mechanism are utilised to meet off-road vehicle requirements. A dynamic model is used to represent the device. Subsequently, experimental tests are performed on an actual prototype to verify the functionality of the damper and validate the proposed model.

  • Design of electromagnetic Shock Absorbers for automotive suspensions
    Vehicle System Dynamics, 2011
    Co-Authors: Nicola Amati, Andrea Festini, Andrea Tonoli
    Abstract:

    Electromechanical dampers seem to be a valid alternative to conventional Shock Absorbers for automotive suspensions. They are based on linear or rotative electric motors. If they are of the DC-brushless type, the Shock absorber can be devised by shunting its electric terminals with a resistive load. The damping force can be modified by acting on the added resistance. To supply the required damping force without exceeding in size and weight, a mechanical or hydraulic system that amplifies the speed is required. This paper illustrates the modelling and design of such electromechanical Shock Absorbers. This paper is devoted to describe an integrated design procedure of the electrical and mechanical parameters with the objective of optimising the device performance. The application to a C class front suspension car has shown promising results in terms of size, weight and performance.

  • ELECTROMAGNETIC Shock Absorbers FOR AUTOMOTIVE SUSPENSIONS: ELECTROMECHANICAL DESIGN
    Volume 2: Automotive Systems Bioengineering and Biomedical Technology Fluids Engineering Maintenance Engineering and Non-Destructive Evaluation and Na, 2006
    Co-Authors: Nicola Amati, Aldo Canova, Fabio Cavalli, Stefano Carabelli, Andrea Festini, Andrea Tonoli, Guglielmo Caviasso
    Abstract:

    This article illustrates the modeling and design of electromechanical Shock Absorbers for automotive applications. Relative to the commonly used hydraulic Shock Absorbers, electromechanical ones are based on the use of linear or rotative electric motors. If electric motor is of the DC-brushless type, the Shock absorber can be devised by shunting its electric terminals with a resistive load. The damping force can be modified by acting on the added resistance. An integrated design procedure of the electrical and mechanical parameters is presented in the article. The dynamic performance that can be obtained by a vehicle with electromechanical dampers is verified on a quarter car model.
