【摘要】 本文提出了一种新型结构压缩机网状阀缓冲片—自弹缓冲片。运用有限元软件ANSYS对自弹缓冲片进行结构静力分析,计算其变形、刚性系数及应力。采用瑞利法,通过ANSYS计算自弹缓冲片等效运动质量。分析自弹缓冲片各结构参数对其变形、刚性系数、应力及等效运动质量的影响,得到了简便的工程计算公式。建立了带自弹缓冲片压缩机网状阀工作过程数学模型,从保证气阀良好运动规律的角度,分析了自弹缓冲片工程设计时要满足的要求,用来指导自弹缓冲片的设计。带自弹缓冲片压缩机网状阀应用于一系列大、中型压缩机气阀设计或改造,证明自弹缓冲片刚性系数大,能承受较大的缓冲片弹簧力,缓冲片自身工作过程应力小,带自弹缓冲片压缩机网状阀具有良好的可靠性。更多还原

【Abstract】 A new structural self-elastic damping plate of the compressor plate valve was presented in this paper. Then, the displacement, stiffness coefficient and stresses of the damping plate were calculated by means of ANSYS, a finite element analysis software, and the equivalent motion mass of the damping plate was calculated by means of Ray-Ieigh with ANSYS. And then the methods for engineering design was proposed through the analysis of the results that the displacement, stiffness coefficient, stresses and equivalent motion mass of the damping plate were calculated by means of FEM with different structural parameters. And the mathematical models of this valve were established, the request designing the self-elastic damping plate was also presented for ensuring there is good motion law in the valve and guiding the design of the self-elastic damping plate. The valves with self-elastic damping plate are used in series of large and middle-sized compressors, which proves their stresses in the working process were smaller and the larger spring force could be loaded on the damping plate because their stiffness coefficients were higher, so the reliability of this valve is higher.更多还原
