Research on the Performance of Distributed Hydraulic Drive System for Articulated All-terrain Vehicles
摘要
Abstract
Emergency rescue vehicles need to adapt to various complex terrains with higher requirements for reliability and redundant safety.In response to the operational requirements of heavy-duty articulated all-terrain vehicles,a distributed hydraulic drive system with 4 variable displacement pumps and 4 variable displacement motors has been designed.An AMESim simulation model of the distributed hydraulic drive system is established,and data on engine speed and load rate,vehicle speed,as well as the inlet and return pressure and flow rate of the distributed hydraulic drive system under typical operating conditions are obtained.The influence of the variable motor displacement on the speed regulation performance of the distributed drive system for all-terrain vehicles has been investigated.The heavy-duty articulated all-terrain vehicle has undergone real vehicle testing,and its distributed hydraulic drive system is stable and reliable.The vehicle's rapid acceleration time is 25 s,the maximum speed is 34 km/h,which basically meets the parameter design requirements.关键词
