动力传递系统是矿用自卸车最重要组成单元,系统中轮边减速器和主减速器减速比的合力分配是动力性能发挥和整车减速增扭平稳运行的重要保证,采用协同优化对矿用自卸车动力传递系统进行优化设计。根据矿用自卸车传动系统结构特点和性能特征,将传动系统动力匹配作为系统级,而主减速器和轮边减速器作为子系统级。对轮边减速器和主减速器进行数学建模,并对各减速装置单独优化分析。基于i SIGHT实现矿用自卸车轮边减速器和主减速器协同优化的过程集成和优化求解。对比各自单独优化和系统整体协同优化分析结果可知:整体系统的协同优化可以系统地解决矿用汽车减速系统的优化匹配问题,同以往将全局设计变量作为固定参数进行处理的常规优化相比,其优化结果更符合实际工程问题。
The power transmission system is the most important component of the mining dump truck. The resultant distribution of the reduction ratio of the wheel reducer and the final drive in the system is an important guarantee for the dynamic performance of the vehicle and the steady operation of the vehicle deceleration and twisting. The cooperative optimization of the mining Dump truck power transmission system for optimal design. According to the structural characteristics and performance characteristics of the drive system of mining dump truck, the powertrain power matching is taken as the system level, while the main reducer and the wheel reducer as the subsystem level. Mathematical modeling of the wheel reducer and the final drive, and the individual optimization of the deceleration device analysis. Process Integration and Optimization Solution of Synergic Optimization of Mine Dumping Wheelset and Final Drive Based on i SIGHT. Comparing the results of individual optimization and the overall optimization of the system, it can be seen that the overall system collaborative optimization can systematically solve the optimization matching problem of the mining vehicle deceleration system. Compared with the conventional optimization which used the global design variables as the fixed parameters, Optimization results more in line with the actual engineering problems.
