摘要: 为改善跨座式单轨车辆运行平稳性,研究水平轮胎结构形式对单轨车辆运行平稳性的影响。建立跨座式单轨车辆多刚体动力学模型,采用Sperling指标作为运行平稳性的评价标准,分别分析了配置子午线轮胎和斜交轮胎的单轨车辆在不同载荷和运行速度下的运行平稳性。结果表明:在不同速度和载荷状态下,配置子午线轮胎水平轮的车辆横向平稳性优于配置斜交轮胎水平轮的车辆横向平稳性;配置子午线轮胎的车辆垂向平稳性在常用运行速度区间内优于配置斜交轮胎的车辆垂向平稳性;换装子午线轮胎水平轮可以改善车辆运行平稳性。

Abstract: In order to improve the running stability of straddle type monorail vehicle, the influence of horizontal tire structure on the running stability of monorail vehicle was studied. A multi-rigid body dynamic model of straddle type monorail vehicle was established, and the Sperling index was used as the evaluation standard of running stability. The running stability of monorail vehicle with radial tire and bias tire under different loads and running speeds was analyzed respectively. The analysis shows that: under different speed and load conditions, the lateral stability of the vehicle equipped with radial tire horizontal wheel is better than that of the vehicle equipped with bias tire horizontal wheel; the vertical stability of the vehicle equipped with radial tire is better than that of the vehicle equipped with bias tire in the common running speed range; changing radial tire horizontal wheel can improve the running stability of the vehicle.

Key words: vehicle engineering; straddle monorail vehicle; horizontal tire form; radial tire; bias tire; operational stability analysis
