| dc.description.abstract | In this study, the effect of stiffener plate thickness on stress of truck chassis using finite element method focusing on Volvo truck chassis is performed. The main goal of the research is optimization of stress on joints of the chassis by adding stiffener plates between joints of side member, cross member and on top of connector plate flanges. The stiffeners are fastened by means of bolt and rivet. In order to achieve reduction in magnitude of stress on joints of the chassis stiffener plate thickness are varied (3mm to 8mm). For analysis, High strength low alloy steel existing truck chassis structural steel material is used. Analytical analysis of maximum stress and maximum deformation are done on existing chassis to select the cross member for further modeling and analysis. Both existing and modified truck chassis drawings are modeled using CATIAV5R19 and the finite element analysis is done using ANSYS14.5. Then, the finite element analysis result showed that the magnitude of equivalent (von-miss) stress using stiffener plates thickness of (3mm-8mm), the value of the stress reduced (190Mpa77.6Map) respectively and according the result (36.9% - 59.0%) of stress optimized. The magnitude of deformation using stiffener plates thickness of (3mm-8mm), the value of deformation reduced (0.34mm-0.266mm) respectively and according the result (11.8% - 22%) of deformation optimized as compared with existing chassis. Due to stiffener plate thickness of (3mm-8mm) added to existing chassis weight of modified chassis is increased (72.69kg - 89.52kg) respectively and according the result (9%-18%) of weight is increased. Finally, the finite element analysis results comparable with literature results and the difference is less than 10%. | en_US |
