摘　　要：以某型煤矿车辆前机架的三维模型为研究对象,利用有限元软件分析了在不同极限工况下的静力变形位移响应,研究了该前机架的固有振动特性并且得出其第3阶模态振动对驾驶室座椅处的振动灵敏度最大。在随机载荷的连续作用下,疲劳安全系数大于1,可为后续其他类似车架结构优化设计提供一定的参考。Taking the 3D model of a front frame in auxiliary carriage vehicle as the study subject,using the finite element software to analyse the static deformation displacement response under different extreme conditions.Through study the the natural vibration character of the frame,it is concluded that its third-order modal vibration is most sensitive to vibration at the cab seat.The fatigue safety factor is more than 1 under the continuous action of random load,which can provide a reference for the subsequent optimization design of other similar frame structures.
