Abstract: This thesis aimed at the realization of the LUM based on Longitudinal-flexural mode, and studied on its model design, simulation, manufacture and experimentation. The following are the chief research work and achievements of this thesis. The  motor is a new type of LUM based on the vibration in plane of the thin plate. Some experiments and research work related to the two sample motors, the experimental results show that all performed well, and the expected design objective has been successfully obtained.
Key words: linear ultrasonic motor (LUM), vibration in plane, thin rectangular plate, longitudinal-flexural mode
