スクリュー圧縮機ロータ系の衝突振動解析 : 第2報,駆動側,反駆動側両歯面が衝突する場合

抄録

In the screw compressor, a periodically fluctuatig torque occurs when gas pressure rises in the grooves of the rotor. An impact vibration between the male and female rotors is analyzed, in the case that movement of the male rotor is ignored. Impact occurring at both the driving and trailing sides is considered. The condition under which the periodical impact vibration occures is dependent upon the ratio of mean to amplitude of female torque. At all regions except the stable region of the periodical impact vibration, only the impact-damped vibration occurs, and the compressor is driven quietly.
