摘要

摘要: 在Hypermesh中建立TY型自卸车车架有限元模型,对车架进行了弯曲和扭转工况下的强度与刚度分析,并通过模态试验验证了有限元模型的准确性.对车架部件进行柔度灵敏度、模态灵敏度和质量灵敏度的计算,基于相对灵敏度分析的结果确定优化设计变量,在保证车架刚度和低阶模态频率的前提下,对车架结构进行轻量化优化.结果表明:优化后车架的强度、刚度和低阶模态频率均有所提高,避免了应力集中现象,车架质量减少70 kg,验证了该轻量化设计方法的可行性.

Abstract: The finite element model of TY dump truck frame was established in Hypermesh. Analysis for strength and stiffness of the frame was done under bending and torsion conditions,and the accuracy of the finite element model was verified by modal tests. Through analyzing flexibility sensitivity,modal sensitivity and quality sensitivity for frame parameters,the optimal design variables were determined based on the results of the relative sensitivity analysis. The lightweight optimization design was applied in the frame structure under the condition of meeting the stiffness and low order modal frequencies. The results show that the strength,stiffness and low order modal frequencies of the optimized frame are increased,the stress concentration is avoided,and the frame weight is reduced by 70 kg,which illustrate the validity of the lightweight design method.
