An experimental characterization of earthquake effects on mechanism operation

In this paper we have reported an experimental study for the effect of earthquake motion on the operation of a mechanism. A prototype of CaPaMan (Cassino Parallel Manipulator) has been used as suitable earthquake simulator in order to reproduce 3D seismic motions with easy-operation robust features. Experimental tests have carried out by using a four-bar linkage as test-bed mechanism and results are reported to show characteristic seismic effects on mechanism operations.
