Abstract
A hybrid motion simulator generally suffers from a problem in which the kinetic energy of the system increases during contact because of delay times. This paper presents a compensation method for that problem. A dead time model that represents various delay times of the system is presented, and how the kinetic energy of the system is increased by the dead time is clarified. On the basis of that, a method to compensate for the dead time is proposed. This compensation method realizes a variable coefficient of restitution in the hybrid motion simulation. After that, experiments of uniaxial collision are conducted to evaluate the proposed compensation.
