为了研究车载环境下压电悬臂梁的结构参数变化对压电振子发电量的影响，根据压电方程建立了压电悬臂梁的等效模型，仿真分析了各结构参数对悬臂梁压电装置的固有频率和输出电压的影响规律。研究结果表明，适当增大悬臂梁自由端质量块的质量和悬臂梁的长度，减少悬臂梁的宽度和中间金属层的厚度，可使压电悬臂梁的固有频率降低，接近环境振动频率，从而使输出电压增加，提高压电装置的发电能力。

In order to measure and study the effects of structural parameters for a piezoelectric cantilever installed on vehi -cles, an analytical model of the piezoelectric cantilever was established by using the piezoelectric theory .The effects of structural parameters on natural frequency and output voltage were analyzed by numerical simulation .The research results show that the nat-ural frequency of the piezoelectric cantilever decreased , and the output voltage increased when the mass of the mass block and the length of the cantilever increased and the width of the cantilever and the thickness of the middle metal layer decreased .These measures finally improved the generating capacity of the cantilever .
