某矿用防爆胶轮车轻量化设计研究

Study on lightweight design of a mine explosion-proof rubber-tyred vehicle

为了减轻某矿用防爆胶轮车的整体质量,根据其行驶工况和承载情况,分别建立了前后车架的CAD模型和有限元模型,采用有限元法对车架进行了应力分析,以评价车架结构的强度。在有限元分析的基础上,对现有车架结构进行轻量化设计,车架质量减小了36%。分析结果表明,优化后模型的应力强度小于材料的许用应力,优化结果是可行的,为胶轮车的改进设计提供了理论依据。

In order to reduce the whole mass of a mine explosion-proof rubber-tyred vehicle,the CAD model and finite element model of the front and the back frame are established respectively according to driving conditions and load conditions of the rubber-tyred vehicle,then the strength of the frame is assessed through stress analysis with the finite element method.Based on the stress analysis results,lightweight design of the frame is carried out,and the mass of the frame is decreased by 36%.Analysis results show that the stress intensity of the optimized frame model is less than the material allowable stress,and the optimization results are valid,which provides theoretical basis for the improvement design of rubber-tyred vehicles.
