TP1700型运梁车驱动系统同步控制设计与应用

TP1700型运梁车采用分体式4车独立驱动系统,针对其同步精度要求高的问题,进行了理论分析及仿真研究,提出了使用压力与转速信号的同步控制方法。基于液压传动系统的规律,将其简化成泵变量机构与泵控马达两部分。以某一车为基准信号,调节其余车泵的排量,根据系统结构特点,分别满足不同车之间压力同步或转速同步。利用AMESim软件对系统进行建模与仿真,通过与实测数据进行对比,验证了仿真模型的准确性和系统原理的正确性。仿真和实际使用结果表明,采用压力与转速信号的同步控制方法,能够有效保证系统的同步性。

Design and Application for Synchronous Control of TP1700 Transporter Driving System

The TP1700 transportor uses 4 independently driving system, aiming at the problem of high precision synchronization system, by the theory analysis and simulation, a synchronization control method is presented which uses the pressure and speed signal. By the rule of the hydraulic transmission system, it was simplified to the displacement varying mechanism and pump controlled motor system. Based on a signal from one transporter, the pump displacement of others were adjusted, according to the characteristic of system structure, it could meet the requirement of the speed synchronization control method or pressure synchronization control method from the different transporters. The modeling and simulation of the system was carried out by using AMESim software, and through the comparison results between simulation and test date that the simulation model was accurate and the system principle was correct. The simulation and practical use results show that the synchronization control method which uses pressure and speed signal can effectively guarantee the synchronization of system.
