分析了预紧力和振动幅值对声表面波直线电机驱动性能的影响，建立了声表面波直线电机的仿真模型。实验结果表明，声表面波直线电机的最大输出力和最大输出功率取决于电机的预紧力。最大输出力和最大输出功率所需的最佳预紧力都是SAW直线电机振幅的线性函数。然而，SAW直线电机的空载速度随着预载的增加而线性下降。提出了一个新的模拟模型来解释这些现象。实验结果与模拟结果吻合较好。
This paper describes influences of a pre-load and vibration amplitude on driving performance of a surface acoustic wave (SAW) linear motor, and proposes a simulation model for the SAW linear motor. In experimental results, maximum output force and maximum output power of the SAW linear motor depended on it's pre-load. Optimum pre-loads for the maximum output force and for the maximum output power were both linear functions of the SAW linear motor's vibration amplitude. No-load velocity of the SAW linear motor, however, decreased linearly with increasing pre-load. A new simulation model to explain these phenomena is proposed. There is a good agreement between the experimental and simulation results.
