高速3轴转向架技术方案的研究

Research of technology project for high-speed three axles bogie

通过对200 km/h速度级C0-C0轴式大功率交流传动客运电力机车转向架关键动力学项点的研究,提出电机驱动系统弹性架悬的高速3轴转向架总体结构方案,分析了转向架3个轮对一系弹簧不等刚度的设计和牵引杆车体布置位置对其动力学的影响。详细介绍转向架的结构参数方案,并计算其动力学性能,结果表明该转向架具有优良的动力学性能,能满足200 km/h速度的运用要求。

According to the research of the key points of dynamics for the bogie of 200 km/h Co-Co high power AC electric passenger locomotive, this paper proposes the high-speed three axles bogie structure project of traction motor drive systems suspended flexibly in bogie frame, and analyzes the unequal stiffness design method for three wheel sets of primary suspension and the influence of the dynamics about traction rod arrangement in the end or the middle of the body. Based on the dynamic analysis, this paper expounds the bogie structure and parameter, and calculates the bogie dynamic performance. The result shows that the dynamic performance of the bogie is well to satisfy the running requirements at 200 km/h.
