A Research on the Influence of Joint Screw on the Dynamic Property of the System

摘要

Through the dynamic property test of the two pair of specially designed specimen, the influence of joint screw on the dynamic property is analyzed. The essential factor brought by the threads joint state and machining error that change the proportion between thread shoulder surface and the thread pair is explained. And the effective way to change or control the dynamic property of the system is put forward, that is increasing the machining precision and changing the structure of the accessory.
