摘　　要：为揭示旋叶式压缩机排气阀片启闭运动规律及影响因素,建立排气阀片单质点模型,借助四阶Runge-Kutta算法求解,研究排气阀片启闭过程运动规律,分析阀片有效工作长度、质量及弹力与阀片振动位移的关联关系;而后,搭建旋叶式压缩机排气阀片开度试验台,开展排气阀片位移测试,以验证旋叶式压缩机排气阀片运动模型的合理性;进而,研究阀片升程、厚度等设计参数对阀片位移的影响规律。研究结果表明:理论计算结果与试验规律较为吻合;增大升程限制器圆弧段长度可减小排气阀片颤振;阀片厚度过大,阀片将无法全开,导致出现过压缩问题。In order to reveal the opening and closing motion law and influencing factors of the discharge valve plate of the rotary vane compressors,a single-particle model of the discharge valve plate is established and solved by the fourth-order Runge-Kutta method.The movement law of the opening and closing process of the discharge valve plate is studied,and the relationship among the effective working length,mass and elastic force of the valve plate and the vibration displacement of the valve plate is analyzed.Then,the test-bench of the opening degree of the discharge valve plate of the rotary vane compressor is built.The displacement test of the reed valve is carried out to verify the rationality of the movement model of the reed valve of the rotary vane compressor.Furthermore,the influence of the design parameters such as the lift and thickness of the valve on the displacement of the valve is studied.The results show that the theoretical calculation results are in good agreement with the test rules;increasing the length of the arc section of the lift limiter can reduce the chatter of the reed valve plate;if the thickness of the valve plate is overlarge,the valve plate cannot be fully opened,which will result in over compression problem.
