中文摘要：

提出一种新型结构自弹缓冲片,这种缓冲片中心无弹性臂,自身设计成为一弹性体。自弹缓冲片刚性系数较大,可采用较大缓冲片弹簧力,同时自身工作过程应力较小,具有良好的可靠性。对带自弹缓冲片网状阀结构设计进行阐述,利用ANSYS有限元分析软件计算自弹缓冲片刚性系数、等效运动质量及应力,并给出了其工程计算公式以方便自弹缓冲片的设计。带自弹缓冲片网状阀应用于一系列大中型压缩机气阀设计或改造,效果良好。

英文摘要：

A new self-elastic damping plate is presented. There are no elastic arms in the center of the damping plate, and the damping plate is designed as a se1f-elastic plate. Because of the higher stiffness coefficient of the damping plate, the larger spring force can be loaded on it. Because of the smaller stresses in the working process, the reliability of the damping plate is higher. The struc-tural design of the valve with self-elastic damping plates is illustrated. The stiffness coefficient, the stresses and the equivalent mo-tion mass of the self-elastic damping plate are calculated by ANSYS software. Their engineering calculation formulae are provided for the easier design of the self-elastic damping plate. The valves with the self-elastic damping plates are used in series of large and middle-sized compressors, and the results are good.
