Abstract

This paper proposes a novel 6-DOF (Degree of Freedom) heavy-load parallel manipulator with redundant actuation and fault-tolerant actuator (RFTA). The RFTA model of the proposed manipulator is developed and its working principle is described. In order to achieve the given motion, the mathematic models of the proposed manipulator with RFTA are derived. As a prototype of an earthquake simulator, two experiments are performed. The results of the redundant driving force experiment demonstrate that the RFTA is able to supply the required double driving force and appropriate used as an actuator of a low frequency earthquake simulator. The results of the fault-tolerant experiment show that the earthquake simulator with RFTA is capable of tolerating some local faults. The proposed parallel manipulator can also be applied under other heavy-load environments.
