  • perfect Sound Insulation Property of reclaimed waste tire rubber
    SUSTAINABLE ENERGY AND ADVANCED MATERIALS : Proceeding of the 4th International Conference and Exhibition on Sustainable Energy and Advanced Materials, 2016
    Co-Authors: Iwan Yahya, Restu Kristiani, Eki Muqowi, Saiful Amri Mazlan
    Abstract:

    This article reports an experimental investigation of Sound Insulation and absorption performance of a materials made of reclaimed ground tire rubber which is known as un-recyclable thermoset. The bulk waste tire is processed using single step recycling methods namely high-pressure high-temperature sintering (HPHTS). The bulk waste tire is simply placed into a mold and then a pressure load of 3 tons and a heating temperature of 200°C are applied to the mold. The HPHTS conducted for an hour and then it is cooled in room temperature. The resulted product is then evaluated the acoustical properties namely Sound transmission loss (STL) and Sound absorption coefficient using B&K Tube Kit Type 4206-T based on ISO 10534-2, ASTM E1050 and ASTM E2611. The Sound absorption coefficient is found about 0.04 until 0.08 while STL value ranges between 50 to 60 dB. The Sound absorption values are found to be very low (<0.1), while the average STL is higher than other elastomeric matrix found in previous work. The reclaime...

  • On Sound Insulation of pyramidal lattice sandwich structure
    2018
    Co-Authors: Liu Jie, Chen Tingting, Wen Guilin, Qing Qixiang, Sedaghati Ramin, Xie, Yi Min
    Abstract:

    Pyramidal lattice sandwich structure (PLSS) exhibits high stiffness and strength-to-weight ratio which can be effectively utilized for designing light-weight load bearing structures for ranging from ground to aerospace vehicles. While these structures provide superior strength to weigh ratio, their Sound Insulation capacity has not been well understood. The aim of this study is to develop numerical and experimental methods to fundamentally investigate the Sound Insulation Property of the pyramidal lattice sandwich structure with solid trusses (PLSSST). A finite element model has been developed to predict the Sound transmission loss (STL) of PLSSST and simulation results have been compared with those obtained experimentally. Parametric studies is then performed using the validated finite element model to investigate the effect of different parameters in pyramidal lattice sandwich structure with hollow trusses (PLSSHT), revealing that the pitching angle, the uniform thickness and the length of the hollow truss and the lattice constant have considerable effects on the Sound transmission loss. Finally a design optimization strategy has been formulated to optimize PLSSHT in order to maximize STL while meeting mechanical Property requirements. It has been shown that STL of the optimal PLSSHT can be increased by almost 10% at the low-frequency band. The work reported here provides useful information for the noise reduction design of periodic lattice structures
