推土机传动和控制涉及各种不同的物理能量形态,许多零件局部参数对于整机性能的影响相互耦合,量化困难。为解决以推土机为代表的工程机械多工况、多能态、难量化问题,综合底盘、地面力学、机械、液力、液压传动等理论,以系统工程理论为建模方法,以计算机为仿真工具,建立了液力传动推土机机电液一体化系统模型。针对液力传动推土机样机进行动态性能测试试验,试验和仿真两者相辅相成,通过试验结果来验证模型和仿真的准确性,通过仿真来弥补试验可重复性差的缺陷。开发了液力传动推土机性能分析软件平台。
Bulldozer transmission and control involves a variety of physical energy forms, many parts of the local parameters of the performance of the machine coupled to each other, quantitative difficulties. In order to solve the multi-condition, multi-state and hard-to-quantify problems of construction machinery represented by bulldozers, the theory of integrated chassis, ground mechanics, mechanical, hydraulic and hydraulic transmission, the system engineering theory as modeling method and the computer as simulation Tools, established a hydraulic transmission bulldozer mechatronic system model. According to the dynamic performance test of hydrodynamic bulldozer prototype, the experiment and the simulation are mutually reinforcing. The accuracy of the model and the simulation is verified by the test results, and the defects of the poor repeatability of the experiment are compensated by the simulation. Developed hydraulic transmission bulldozer performance analysis software platform.
