结合交叉拉杆有限元分析,建立了完整的转K2货车动力学模型;通过数值计算,得到了交叉拉杆的各阶自由振动模态以及理想曲线通过和随机激扰下的振动与受力特性,为研究交叉拉杆结构的疲劳寿命奠定了基础.
Combined with the finite element analysis of the cross-tie rod, a complete kinetic model of the K2 turning truck is established. Through the numerical calculation, the free vibration modes of the cross-tie rod and the vibration and force characteristics of the cross-tie rod under random excitation are obtained. Studying the fatigue life of cross-tie bars lays the foundation.
