This paper presents a mechanism which can adjust inertia, containing a flywheel, a group of clutches, a direction converter, and a magnetorheological hydraulic actuator. Conventionally, among impedance factors of the mechanical system, inertia seems to be unchangeable, not like damping factor or elasticity. However, changing inertia might bring different behavior to mechanical networks. In this study, by controlling the flywheel energy collected from the motor pump to release to the object, the resistance of actuator motion can be adjusted. We call this the pseudo-inertia adjustable mechanism (pIAM). The experimental results shows that the machine can release the maximum torque about 7 Nm and the maximum speed about 800 deg/s with 1000 rpm of the flywheel speed, which reveals the feasibility of this mechanism.
