which is suited for inspecting the pipe of φ20mm diameter were studied. The actuator is made of PZT bimorph
center shaft and mass. With different boundary conditions of bimorph
the response at the first mode natural frequency of actuator were analyzed. FEM( finite element method) were used. The conclusion can be reached that when the fixing degree is 9° or 63°
the response is larger than those of others. All these are the theoretical basis of optimization of this kind of microrobot.
