摘要
针对传统引信电源体积大、寿命短的问题,提出了引信用旋转式冲击压电发电机。该发电机主要由涡轮和压电发电机组成,具有体积小、能量密度高、寿命长等优点。利用MATLAB和ABAQUS分析软件进行了理论分析与计算,仿真结果表明:在30m/s风速下,最佳转换元件数量为4,最佳转换元件数量随着风速的增大逐渐增多,为后续发电机的结构设计提供了理论依据。
Aiming at the problem of large volume, short storage period of traditional fuze power, an impactbased rotary piezoelectric generator for fuze was presented in this paper. The generator was composed of turbine and piezoelectric generator, which had the advantages of small volume, high energy density, long storage period, etc. MATLAB and ABAQUS were responsible for theoretical analysis and calculation. The simulation result showed that the optimum number of conversion elements was 4 and the optimum number of conversion elements gradually increased with the increase of wind speed.
