Slip Motion

The fundamental characteristics of “stick-slip” motion in a machine tool slideway is ascertained experimentally, and it is clarified that the time-dependence of static friction has a great influence on the behavior of the stick-slip motion. An empirical formula is proposed to express the characteristics of static friction and the mechanism of the time-dependence of static friction is examined experimentally and theoretically. The influence of properties of lubricants and surface topography on the static friction is investigated quantitatively. Finally, a general conception to prevent stick-slip motion is offered.

Slip Motion

Stick-slip motion of a moving element on an actual machine tool slideway is investigated experimentally under various sliding conditions, and the fundamental characteristics of the stick-slip motion are clarified. Based on these experimental results, the characteristics of static friction in the period of stick and kinetic friction in the period of slip are studied concretely so as to clarify the stick-slip process. It is shown experimentally that static and kinetic frictional coefficients can be expressed with simple formulas. Using these expressions, the boundary conditions for occurrence of stick-slip motion are examined, and the relation between properties of the stick-slip motion and frictional characteristics is explained quantitatively.

A method is proposed for analyzing the periodic stick-slip motion of a single degree of freedom model of frictionally damped turbine blades. The method of finite elements in the time domain (FET) is based on a Hamilton’s weak principle, paralleling the variational methods in elastostatics. It permits a complete determination of the hysteretic friction force, and results in a set of highly structured system equations. The method has a number of unique features, which are utilized to provide a simple yet efficient approach for predicting the steady-state response. When applied to a number of example problems, including systems with static friction and the excitation of multiple discrete frequencies, the FET method is demonstrated to be an efficient and reliable alternative technique for nonlinear dynamic response analysis.
