摘　　要：在起重机械液压系统中,平衡系统对操控性能影响非常重要。为了改善平衡阀在开启过程中的特性,首先提出了一种控制口流量引导型平衡阀的原理,并通过AMESim仿真与普通控制口流量抑制型平衡阀进行对比。仿真结果表明控制流量引导型平衡系统具有明显的优势,缓冲时间长且无压力冲击。然后,利用仿真软件对控制口流量引导型平衡阀的各参数进行分析,总结其对平衡阀性能的影响。所进行的研究工作对于起重机械液压平衡系统的优化提供了依据。The balance hydraulic system is extremely important to the control performance of crane s hydraulic system.In order to improve features when balance valve is opening,a flow-guiding balance hydraulic valve is advanced first,and then compared with the common flow-inhibiting balance valve by the simulation of AMESim.The simulation results show the flow-guiding balance hydraulic valve has obvious advantages of longer buffer time and no pressure impact.Then it analyses the parameters of the flow-guiding balance hydraulic valve by simulation and summarizes the influence on the performance of balance valve.The research provides foundation for optimization of crane s balance hydraulic system.
