Abstract
Vibration suppression on precision equipments always attracts great attention in industry and academic field. In order to reduce the vibration, many measures are taken in the past few decades. In general, vibration suppression can be classified as either active or passive mode. However, both of them achieve their own vibration-suppression function by attaching external members, which has some shortcomings of the complexity of production assembly. In order to improve vibration-suppression performance of a compliant amplifier, a novel compliant mechanism with metastructures is designed. The metastructures as shock-absorbed unit inserted in the amplifier’s members can have capabilities of vibration suppression for their host structures. The different configurations of the metastructures in the host members are presented. Their frequency response functions are obtained using ABAQUS software, respectively. Through comparisons between their response functions, it indicates that the vibration-absorbing metastructures orienting along horizontal direction, which vibration-suppression direction is consistent with the output direction, have excellent performance of broadband suppression when their natural frequency keep highly coincident with the first order modal frequency of the compliant mechanism.
