1000吨轮胎式提梁机液压驱动系统同步性研究

Research on Synchronization of Hydraulic Drive System for 1000 ton Tire Type Beam Lifting Machine

建立了1000吨轮胎式提梁机驱动系统变量泵和变量马达的数学模型,通过仿真分析了三种不同控制信号下提梁机驱动系统在坡道起动和平地启动的动态特性,得到了在不同工况下变量泵输入的特性参数,通过试验验证了仿真得到的参数能够降低驱动系统同步行走偏差。

The mathematical model of the variable displacement pump and variable motor of the 1000-ton tire-type beam-lifting machine drive system was established.The dynamic characteristics of the beam-lifting drive system of the three different control signals on the ramp start and the ground start were analyzed by simulation.The characteristic parameters of the anti-disturbance input of the lower variable pump are verified by experiments to reduce the deviation of the synchronous walking of the drive system.
