摘　　要：针对青藏客车AM96型转向架抗侧滚扭杆装置固定螺柱断裂问题进行了理论分析,通过动应力测试试验对螺柱的疲劳强度进行了评估,并对其抗侧滚扭杆及安装座进行了结构优化。In view of the beaking of the fixing screw bolt in the anti-rolling torsional bar in AM96 bogies for Qingzang passenger cars,the ttheoretical analysis is made and the fatigue strength of the screw bolt is estimated through dynamic stress testing,and structure optimization is made for the anti-rolling torsional bar as well as the installation seat.

关 键 词：转向架 抗侧滚扭杆 结构优化
