摘　　要：为了对G324牵引车的车架进行强度分析及改进,根据牵引车的实际工况,选择对车架影响较大的弯扭工况进行分析,利用HyperMesh有限元软件建立了某牵引车车架结构有限元分析计算模型。通过计算得出该车架在这两种工况下的应力分布云图,对车架进行改进并分析增加L板和将鞍座瓦轮板改为平板以及取消加强板3种模型的实际情况,得出满足车架强度要求的具体模型,为牵引车车架的设计及改进提供参考依据。In order to analysis and improve the strength of G324 tractor frame, according to the actual condition of the tractor, we analyzed the bending and the torsional conditions which have great impact on the frame and established a finite element calculation model of the G324 tractor vehicle frame using the HyperMesh finite element analysis software. Through calculating the stress distribution of the frame in the two kinds of working conditions, we improved the frame and analyzed the stress distributions of adding L plate, changing the saddle tile wheel plate to plane plate and canceling reinforcing plate, respectively. At last, we figured out the specific model of the frame to meet strength requirements, and the results could provide references for the design and improvement of tractor frame.
