摘要: 本文论述了支承在气体轴承上的“O”型胶圈刚度系数、阻尼系数的测试方法和原理。对三种不同胶料制成的“O”型圈的刚度系数和阻尼系数进行了测试,试验值用图綫形式给出。同时考虑了供气压力和“O”型圈安装压缩量对刚度系数、阻尼系数的影响。

Abstract: This peper discusses the technique and principle for measuring the stiffness and damping coefficients of O-rings in gas bearing. Stiffness and damping coeffieienst for O-rings of three different rubbers were determind experimently. Experimental data are given graphically in this paper. The effect of pressures in gas supply and installed compressibility of O-rings upon stiffness and damping coefficients are also considered.
