    • The present invention includes a method of compensating for differences in the rate of thermal expansion in one or more elements of an electromechanical actuator. The electromechanical actuator can include one or more elements such as a piezoelectric ceramic multilayer actuator (CMA) and a mechanism to amplify the motion of the CMA. A difference in the rate of thermal expansion or coefficient of thermal expansion, CTE, between the materials in the CMA and the amplifying mechanism can cause the two components to vary in size at differing rates as the ambient temperature varies. Since the amplifying mechanism provides substantial amplification of the motion of the CMA, the relative variation in size of the components due to temperature can be translated by the amplifying mechanism as motion of the CMA. This can result in substantial motion of the amplifying mechanism. Replacing a mechanical element in the amplifying mechanism with an element having a different value for the CTE substantially reduces the difference in CTE of the materials, thereby reducing the thermally induced motion of the amplifying mechanism. Further, the material used and the means of interconnecting the replacement element in the amplification device for thermal compensation can maintain high rigidity of the CMA support structure, since the support structure transmits the motion and force of the CMA to the amplifying mechanism as well as applying a compressive preload to the CMA. Further, a high level of compressive preload force can be used as an additional part of the overall design process to adjust the degree of thermal compensation required.
    • 本发明包括补偿机电致动器的一个或多个元件中的热膨胀率差异的方法。 机电致动器可以包括一个或多个元件,例如压电陶瓷多层致动器(CMA)和用于放大CMA运动的机构。 CMA中的材料与放大机构之间的热膨胀率或热膨胀系数(CTE)的差异可导致两种组分随着环境温度变化而以不同的速率变化。 由于放大机制提供了对CMA运动的实质性放大,所以由于温度而导致的部件尺寸的相对变化可以通过放大机制作为CMA的运动来转化。 这可能导致放大机构的大量运动。 使用具有不同CTE值的元件来代替放大机构中的机械元件大大减少了材料的CTE差异,从而减小了放大机构的热诱导运动。 此外,由于支撑结构将CMA的运动和力传递到放大机构以及应用,所以使用的材料和用于热补偿的放大装置中的替换元件的互连装置可以保持CMA支撑结构的高刚度, 对CMA的压缩预压。 此外,可以使用高水平的压缩预载力作为总体设计过程的附加部分来调节所需的热补偿程度。
