چکیده
|
Critical point is a factor that causes chassis fatigue failure. in this study,critical buckling load analysis of truck chassis with arc-length method and the effect of replacing conventional steel with two stainless steels in critical point of truck chassis have been investigated. critical point analysis of stress that may cause the fatigue failure,the fe software,abaqus,is employed. the obtained results from the linear analysis of buckling showed that changing of the chassis materials did not bring about considerable changes in the values of critical loads. post buckling response showed that the imperfection of very small values causes a significant decrease of the critical buckling loads. these reductions make stressful points in chassis. investigation showed that when conventional steel is used in chassis,the amount of displacement and stress is critical in stressful points. this amount of displacement and stress can cause fatigue failure in chassis and reduce the longevity of chassis. © 2015,university of kuwait. all rights reserved.
