Abstract
Amount supporting a engine isolates a vibration caused by a engine. Crackes in a mount by aged deterioration decreses a spring constant of mount, isolation ability and causes noise. We must check a mount if a mount does its function normally. In this paper, we assumed a mount as linear spring and identified its spring constant by solving a inverse problem. To regulate a inverse problem, a singular value decomposition technique was applied. We related a location of exciting force and damaged mount on the identification ability.
