【摘要】 从理论上证明了用于直线型行波超声马达的波形成的可行性。并用制作的两个超声压电换能器、自由－自由梁和滑块组成了一台直线型行波原型超声马达。试验表明：这台直线型原型超声马达能作直线往复运动更多还原

【Abstract】 Demonstrates in theory the feasibility of generating the traveling wave used for linear traveling wave ultrasonic motors.A prototype of the linear motor is constructed.It is mainly consists of two piezoelectric transducers,a free free beam and a slider. Tests for the motor show that the slider can move back and forth on the straight beam,thus develoing such a prototype successfully for the first time in China.更多还原
