HX_D1型机车牵引装置螺栓组应力数值模拟

Numerical Simulation for the Bolts Group Stress of Traction Device on Type HX_D1 Locomotive

对HXD1型机车牵引装置螺栓组加衬套前后的2种结构分别建立了有限元模型进行数值模拟计算,结果表明加衬套后螺栓的应力降低约一半,螺栓组利用率偏低。

Established FEM model about both of bolts group model with bush or no for simulating the stress of bolts,The FEM simulation analysis results show that the stress of bolts group model with bush depress moiety,and the utilization ratio of bolts group is on the low side.
