摘　　要：排放法规的日益苛刻,使得用压电陶瓷微制动元件作为共轨喷油器的执行器成为方向之一,研究开发建立的压电执行器性能测试及评价系统,实现对电参数、迟滞特性、刚度、动态特性、负荷影响、温度影响等的测试,为共轨喷油器总成的设计及提高喷油器总成性能提供了依据,通过试验证明了该系统的准确性。Piezoelectric actuator will became a trend as injector actuator to meet increasingly demanding emission regulations,piezoelectric testing and evaluation system for common-rail injector were designed in the paper. The system was built to test hysteresis,stiffness,dynamic capability of piezoelectric actuator,temperature influence to piezoelectric actuator and load,also it was used to verify the accuracy of piezoelectric system.
