✦ Synopsis

The transient vibration of a high-speed feed drive system is investigated. In this study, an analogue vibratory equivalent model with multi-degree of freedom assembled with spring, mass and damper is used to simulate the dynamic behavior of a feed drive system. The worktable is capable of travelling at variable speed and can be brought to a halt at a desired position on the supporting structure. The focus is placed on the vibration response caused by the moving table subjected to di!erent velocity motion programs. Results show that doubling the table moving speed raises more than four times of the table displacement at the moment that the table stops. A motion program with abrupt changes in the velocity and the acceleration should be avoided. Moreover, the symmetrical motion program leads to less vibration in the horizontal direction for the supporting structure.
