摘要/Abstract

摘要：

多轴液压助力转向系统普遍存在转向杆系变形和断裂的问题。基于轮胎原地转向阻力矩的半经验公式，利用ADAMS和AMESim建立了某多轴转向车辆的机液联合仿真模型。在验证模型正确性的基础上,以转向杆系受力最小为优化目标,进行了转向油缸和轮胎原地转向阻力矩的匹配优化。研究发现，转向油缸与轮胎原地转向阻力矩的匹配关系对转向杆系的受力影响非常明显，优化后转向杆系受力显著减小。

Abstract:

Steering linkage deformation or crack was prevalent in multi-axle hydraulic assisted steering system.Based on a semi-empirical formula of tire static steering resistance moment,a mechanism-hydraulic co-simulation model of a multi-axle steering vehicle was built by ADAMS and AMESim software and the correctness was verified by experimental tests.Taking the minimum force of steering linkage as optimization objective,the matching relationship between hydraulic steering system and tire steering resistance moment was optimized.The research shows that the matching relationship has obvious effect on the steering linkage force.The steering linkage force is reduced significantly by matching optimization.

Key words: multi-axle steering, matching design, hydraulic assisted steering, tire static steering resistance moment
