摘要
为提高车辆的稳定性和平顺性,通过ADAMS/CAR模块建立矿用防爆无轨胶轮车前钢板弹簧悬架模型,分析车轮跳动对前轮外倾角、前轮前束角、主销内倾角、主销后倾角等四个车轮定位参数的影响。通过研究分析,确定了影响前钢板弹簧悬架模型的优化目标为前悬主销后倾角和前束角。采用灵敏度分析法对影响前悬主销后倾角和前束角的主要硬点参数变量进行分析,确定需要优化的关键硬点坐标作为设计变量并对硬点坐标进行优化。优化结果表明,关键硬点位置对车辆钢板弹簧悬架的跳动有很大影响,对关键硬点位置进行优化可以显著减小车辆的跳动,为矿用防爆无轨胶轮车的悬架设计提供了重要依据。
In order to improve the stability and smoothness of trackless rubber tire vehicle,the front leaf spring suspension model of the mine explosion-proof trackless rubber-tyred vehicle was established using ADAMS/CAR module,and the influence of wheel runout on four wheel alignment parameters,including front wheel camber,front wheel toe angle,kingpin camber angle and kingpin camber angle,was analyzed.According to the research and analysis,the optimization targets affecting the front leaf spring suspension model are the caster angle and toe angle of the kingpin of the front overhang.The sensitivity analysis method was used to analyze the main hard-point parameter variables affecting the caster angle and toe-in angle of the kingpin in the front overhang,and the key hard-point coordinates to be optimized were determined as design variables and the hard-point coordinates were optimized.The optimization results show that the position of the critical hard point has a great influence on the runout of the leaf spring suspension of the vehicle,and the optimization of the key hard point position can significantly reduce the runout of the vehicle,which provides an important basis for the suspension design of the explosionproof trackless rubber-tyred vehicle for mining.
