The bridge mechanism is one of the most widely used displacement amplification mechanism in microscale applications due to its compact and symmetrical structure. However, a disadvantage of the bridge mechanism is the limited magnification, which limits its further application. To address this issue, this paper designs a compliant displacement amplification mechanism incorporating a lever-type mechanism as the input end of the bridge-type mechanism. This design includes two bridge-type mechanisms and one lever-type mechanism, resulting in a three-stage amplified output displacement. Compared to traditional designs, this amplification mechanism not only maintains a compact and symmetrical structure but also achieves a high amplification ratio and a high natural frequency. Static and dynamic models of the amplification mechanism are established using the compliance matrix method and the Lagrangian method, respectively. The statics and dynamics of the compliant amplification mechanism were simulated and analyzed by using ANSYS to validate the accuracy of the theoretical model. It can be found that the mechanism amplification ratio is as high as 64.6 times, and the first-order natural frequency is 93.6 Hz.
