【摘要】 铰接式履带车的行驶工况恶劣,不可预知的冲击会对分动箱-差速器性能造成一定的影响。以分动箱-差速器为研究对象,首先在Pro/E中建立箱体三维模型,再通过HyperMesh软件建立箱体有限元模型,最后在Romax Designer中建立分动箱-差速器的刚柔耦合模型,并在此环境下对其最危险工况进行强度刚度分析,同时计算轴承在规定载荷谱下的寿命。更多还原

【Abstract】 An articulated crawler vehicle would travel under severe road conditions unexpected impacts could act against the sub-transmission-differential with certain effects thereon. The study object is set of the sub-transmission-differential that first of all is to establish a 3-D model for the box within Pro/E before setting up a finite elements model for the box through a software HyperMesh, and finally setting a rigid-flexible coupling model for the sub-transmission-differential, while carrying out a strengthrigidityanalysis in case of most risky surrounding conditions, at the same time computing the bearing’s working life under regulated load spectrum.更多还原
