| 摘 要： | 为克服喷杆位姿控制时液压系统冲击性大、压力稳定性差等问题,基于负负载、负载敏感与电液比例控制技术设计了喷杆喷雾机悬架液压系统。利用AMESim-ADAMS联合仿真技术,验证了喷杆悬架动载过程中各动作工况下液压系统的稳定性和左右大小折叠液压油缸动作的同步性。结果表明:喷杆液压系统动载情况下压力冲击小,大小折叠液压缸同步误差小于5 mm;基于负载敏感理论和负负载理论设计的喷杆喷雾机悬架负载敏感液压系统符合喷雾机作业要求。对喷杆喷雾机悬架液压系统的研发设计具有借鉴意义。

| Abstract: | To overcome the problems of high impact force and poor pressure stability of the hydraulic system based on the negative load,load sensitivity and electro-hydraulic proportional control technology,the hydraulic system of the boom sprayer's suspension is designed.Using AMESim-ADAMS co-simulation technology,verify the stability of the hydraulic system,the synchronization of the left and right folding hydraulic cylinder in the dynamic load process of the boom suspension frame.The results show that the pressure impact of the boom hydraulic system under dynamic load,size folding hydraulic cylinder synchronization error less than 5 mm.And the load sensitive hydraulic system of boom sprayer's suspension based on load sensitive theory and load theory can meets the sprayer operating requirements,with reference significance for the research and design of suspension hydraulic system of boom sprayer. |
