摘　　要：对大型活动平台状态转换技术进行研究,提出一种电液比例同步控制系统,采用压力触地判断和载荷全程监控策略,实现多个液压支腿的同步伸缩,提高了平台状态转换过程中的同步性和安全性。利用AMESim建立了系统仿真模型,验证控制策略的正确性;并在实际系统中得到充分应用,达到非常好的控制效果。The research is on the big mobile platform state-change. A kind of electro-hydraulic proportional control system is proposed with the control strategies of the touchdown judged by pressure and load supervised all the processes, to achieve synchronical telescopic move of hydraulic legs. The synchronicity and security in the process of platform sate-change are improved. A model of this system is established based on AMESim, to verify the correctness of control strategies. The research results are fully applied in the practical system and the control effect is very good.
