某微车汽车牵引钩挡杆在几种工况下的强度分析

针对目前售后单位反馈的某微车前大梁上拖车的挂绳与前保产生干涉均问题，采用在拖钩底部加一限位用的挡杆的方案，运用Hypermesh建立汽车前大梁部分的有限元模型，模拟实车运行中的5种工况，利用Nastran分析计算这5种工况下汽车牵引钩挡杆处的应力状况，并和原状态下的拖钩应力情况分别作对比.

Strength Analysis of Draw Hook Pin of Certain Automobile on Several Conditions

Targeting on the after-sale＇s feedback of the interference of the sling of trailer of the cross beam and the front safe, the article puts forward a plan to add a pin at the end of the draw hook. The test uses the finite module in front of the beam established by Hypermesh to simulate five different conditions of the real drive. And it uses Nastran to analyze the power reaction at the hook pin then compares with the original power.
