摘要
在工程车称重试验中,会出现轮重、轴重不满足标准要求的情况。目前,调整轮重、轴重的方法是根据经验,在工程车二系旁承支撑处,加不同厚度的钢垫。采用该调整方法存在调整不确定性强、过程繁琐、用时长和劳动强度大等问题。针对这些问题,提出一种基于仿真计算的工程车轮重轴重加垫调整方法。建立工程车轮重、轴重加垫调整模型,采用多目标遗传算法,得到满足轮重轴重要求对应的二系旁承支撑位多种Pareto解,确定轮重、轴重加垫调整方案。分析调整方案影响的敏感度,并进行实例验证。验证结果表明,采用基于仿真计算的轮重轴重加垫调整方法,能够获得多种调整工程车轮重、轴重的方案,为调整轮重、轴重提供指导。
In the weighing test of engineering vehicle,the wheel weight and axle weight do not meet the standard re⁃quirements.At present,the method of adjusting wheel weight and axle weight is to add steel pads of different thick⁃ness to the side supports of the second series of engineering vehicles according to experience.The adjustment method has some problems,such as strong uncertainty for adjustment,tedious process,long time and heavy labor intensity.To solve these problems,a method for adjusting the wheel weight and axle weight of engineering vehicle based on simula⁃tion calculation is proposed.The model for the adjusting wheel weight and axle weight of the engineering vehicle by padding is established,multi-objective genetic algorithm is used to obtain multiple Pareto solutions of secondary side bearing support positions corresponding to wheel weight and axle weight requirements.The scheme for adjusting wheel weight and axle weight is obtained,the sensitivity of the adjustment scheme is analyzed,and the case is veri⁃fied.The verification results show that a variety of schemes for adjusting the wheel weight and axle weight of the engi⁃neering vehicle can be obtained by the method for adjusting wheel weight and axle weight by adjusting steel pad based on simulation calculation,which can provide guidance for adjusting the wheel weight and axle weight.
