摘　　要：提出了一种利用复合弹性材料ＣＦＲＰ（ＣａｒｂｏｎＦｉｂｅｒＲｅｉｎｆｏｒｃｅｄＰｌａｓｔｉｃｓ）的新型超声直线电机。这种电机基于纤维单向排列时ＣＦＲＰ的正交各向异性特点，利用压电振子ＰＺＴ激励ＣＦＲＰ产生倾斜振动，通过导轨表面的反作用力推动电机移动，结构简单，易于制造。A new type of ultrasonic linear motor is analyzed in this paper.The motor is mainly composed of flexible composites CFRP(Carbon Fiber Reinforced Plastic)blocks and a thin plate of PZT ceramic.In the state of ultrasonic resonance,surface of the CFRP block vibrates obliquely and acts on the base.The vibrating motor moves by the reaction from the base.The driving voltage of piezoelectric vibrator is 50V(Vpp);the tractive force is 0 5N;the moving speed is 0￣8mm/s.The motor has a simple structure and is easily made.
