Abstract

To improve suitability in applications with high dynamic performance requirements, the transient response characteristics of high-power piezoelectric transducers should be studied quantitatively. This paper proposes the vector reduction method to solve the complex transient equations and obtains a transient matching scheme clarifying the mechanism of electrical matching resistance on electromechanical damping. A matching scheme with a combination of full-bridge inverter, transformer and series LC circuit is designed and validated, which can provide suitable electrical damping without causing energy losses. Consequently, the experiment verifies the transient properties of the proposed scheme. For a typical piezoelectric cutting transducer with 100.8 ms response time, our scheme is verified to have high dynamic performance within frequency response time of 5.5 ms and vibration response time of 15.0 ms.

摘要

为提高在具有高动态性能要求的应用中的适用性，应定量研究大功率压电换能器的瞬态响应特性。本文提出矢量简化方法来求解复杂的瞬态方程，并获得一种瞬态匹配方案，该方案阐明了电气匹配电阻对机电阻尼的作用机制。设计并验证了一种由全桥逆变器、变压器和串联LC电路组成的匹配方案，该方案可提供合适的电气阻尼而不会造成能量损失。因此，实验验证了所提方案的瞬态特性。对于响应时间为100.8 ms的典型压电切割换能器，验证了我们的方案在5.5 ms的频率响应时间和15.0 ms的振动响应时间内具有高动态性能。
