摘要
针对静强度分析难以准确模拟钢板弹簧后悬架板簧各片之间的动力接触问题,文章以某车型钢板弹簧后悬架为例,在起跳工况下,运用非线性动力学仿真模拟板簧在动载荷持续0.02s下的应力状况。分析结果表明,非线性动力学分析能够准确的模拟板簧的接触过程,并得到板簧的最大应力值及其变化规律,为改进板簧结构设计提供科学依据。
For the static strength analysis,it is difficult to accurately simulate the contact problems between each piece of theleaf spring for rear suspension.This paper takes a vehicle rear leaf spring suspension for example,in the take-off conditions,the use of nonlinear dynamics to simulate the leaf springs under dynamic load stress condition of continued0.02s.The resultsshow that nonlinear dynamic analysis process can accurately simulate the contact leaf springs,and get the maximum stressvalue and its variation of the leaf spring.Scientific evidence is provided to the structure of the leaf spring designimprovements.
