基于HyperMesh悬置支架强度分析

Strength Analysis of Powertrain Mount Bracket Based on Hyper Mesh

悬置支架是动力总成的主要承载部件,其强度必须满足各种极限工况要求。运用HyperMesh这一高性能的有限元前处理器,以某轻型卡车悬置系统为例,建立了该悬置系统的有限元模型,模拟了冲击、驱动、制动和转向四种工况下悬置支架的静强度和刚度,且以主要承力件的应力峰值、主要安装位置的相对位移量作为指标对该悬置系统进行了校核,为新车型悬置系统研发提供一定的参考依据。

Powertrain mount bracket is the main bearing component. Its strength must meet the requirements of all kinds of critical working conditions. Using HyperMesh processor, the finite element preprocessor of high performance, taking a light truck suspension system as an example, the finite element model of the suspension system is established, to simulate static strength and rigidity of mount bracket at the four working conditions namely impact, driving, braking and steering. And the sus- pension system is checked taking the peak stress of the main bearing parts and the main relative displacement of the installation position as the index, to provide certain reference basis for research and development of new vehicles suspension system.
