An experimental evaluation of earthquake effects on mechanism operation

Abstract

The results of successful experiments for investigating the earthquake effects on mechanism operation by using Cassino Parallel Manipulator (CaPaMan) as an earthquake simulator are presented. The experimental tests have been carried on by using a slider-crank and a four bar linkage as representing machine operations. The mechanism behavior has been experienced as strongly influenced when the mechanism motion has low speed as compared to earthquake disturbances. But even at high speed mechanisms are affected by the variable earthquake frequency.
