摘　　要：履带车辆在服役状态下面临复杂恶劣的行驶环境,作为其重要组成部分的综合传动装置液压操纵系统的关键参数会出现性能退化,进而导致换挡品质大幅恶化。为改善综合传动装置在不同服役状态下的换挡品质,研究服役状态下液压操纵系统退化机理,建立包括动力源模型、行星变速器统一动力学模型和负载模型的换挡过程模型。根据换挡品质评价函数,利用遗传算法及全局寻优算法对综合传动装置换挡过程油压曲线进行优化。建立换挡油压曲线优化仿真实验平台,开展车辆不同服役状态下换挡油压曲线优化实验。研究结果表明,换挡油压曲线优化方法能有效改善车辆不同服役状态下的换挡品质。Tracked vehicles face complex and harsh driving environments in service.The key performance parameters of hydraulic control system,as an important component of the integrated transmission device,will undergo degradation,leading to a significant deterioration in shifting quality.In order to improve the shifting quality of the integrated transmission device under different service conditions,the degradation mechanism of the hydraulic control system under service conditions is studied.Then,a shifting process model including power source model,planetary transmission unified dynamic model,and load model is established.According to the shift quality evaluation function,the genetic algorithm and global optimization algorithm are used to optimize the oil pressure curve during the shift process of the integrated transmission device.A simulation experimental platform is established for optimizing and testing the shift oil pressure curves of vehicles under different service conditions.The results indicate that the optimization method for shifting oil pressure curve can effectively improve the shifting quality of vehicles under different service conditions.
