Abstract
We developed a method for estimation of the excitation force of a scroll compressor for air-conditioning systems. The method is based on elastic support method using the measured acceleration response and transfer function of the supporting system. The amplitude and phase of excitation forces were estimated by solving an inverse dynamical problem that used as input the acceleration measured by accelerometers placed on the scroll compressor. The results obtained by the method agreed with the excitation force measured directly by using load cell.
