”Friction Induced Vibrations due to Moving Bodies” The present work investigates the effect of design and operating parameters on the stick-slip motion for three different mathematical models of friction induced vibrations. Ruge-Kutta numerical method is used to solve the equations of motion of the three mathematical models, assuming the case of boundary lubricated contacts.
A test rig has been developed and manufactured to investigate the effect of different parameters on the stick -slip motion of the first model for a number of combinations of contacting surfaces, lubricants, and different slider masses.
The main results have indicated that there are significant effect of the design and operating parameters on the stick-slip motion. It is found that the increase in the drive speed tends to increase the slip time and consequently the displacement and maximum sliding speed. Also stiffer springs and small value of sliding mass provides better stick-slip free motion.
The third mathematical model provides a better stick-slip free motion compared with the other models and steel slideway coated with a hard chrome layer is recommended to reduce stick-slip
