摘　　要：为准确分析HX_(D)1型机车用100型车钩结构优化后在不同载荷下的应变状态,文章介绍了钩缓系统的优化方案,并建立了100型车钩钩体、钩舌的有限元计算模型。将材料的非线性简化为材料的双线性,并采用接触单元的方式进行有限元计算,得出车钩钩体在不同载荷下的应变状态。计算结果显示,优化后的钩体应力应变值均有所下降,说明优化方案是可行性的。In order to accurately analyze the strain state of 100 type coupler structure optimized for HX_(D)1 locomotive under different loads,this paper presents the optimization schemes of coupler buffer system,and establishes the finite element calculation model of 100 type coupler body and coupler tongue.The nonlinearity of material is simplified as the bilinearity,and the finite element calculation is carried out by means of the contact element to obtain the strain state of the coupler body under different loads.The calculation results show that the stress and strain values of the optimized coupler body have decreased,indicating that the optimization schemes are feasible.
