摘　　要：碳纤维作为一种新型复合材料,具有轻量化、高强度等特点。将碳纤维材料应用在地铁车辆转向架上,可以有效地减轻转向架质量,但转向架一系定位刚度过大使得车辆的横向稳定性变差。对车辆转向架横向稳定性进行理论分析,并应用SIMPACK动力学软件对车辆的横向稳定性以及转向架一系定位刚度对车辆横向稳定性的影响进行仿真分析。Carbon fiber,as a new composite material,has the characteristics of lightweight and high strength.The application of carbon fi ber material to vehicle bogies effectively reduces the mass of bogies,however the lateral stability of vehicles becomes bad when the bogies primary suspension positioning stiffness is too big.It theoretically analyzes the lateral stability of vehicle bogies,and uses SIMPACK dynamic software to simulate and analyze the lateral stability of vehicles and the impact of bogie stiffness on vehicle lateral stability.
