Strength Analysis of Tracked Vehicle Gearbox by the Finite Element Method

建立了履带车辆变速箱体的力学模型,对其载荷和结构特点进行了分析,同时根据边界条件,引入特定的约束,通过有限元方法对履带车辆变速箱体进行了结构强度分析,计算得到了等效位移和等效应力云图,分析得出了箱体结构位移和应力的分布及其数值,从而找出了原设计的薄弱环节,可为进一步改进履带车辆变速箱体的结构设计提供一定的参考和借鉴。

In this paper,a detailed finite element model of tracked vchicle gearbox housing is established,the load and structural characteristic is analyzed.According to the boundary condition,constraint condition is applied.The analysis for strength of tracked vehicle gearbox housing is carried out.The nephogram of equivalent stress and displacement is established,and the condition of stress and deformation is obtained under the given load,Weakness of the gearbox housing is put forward,and which provide reference for structural design of housing.
