摘要
波峰系数是衡量大功率航空电源车性能的一项重要指标,为提高分析精度,提出了一种结合抛物线插值法和最小二乘法的波峰系数分析方法。首先,采用抛物线插值法对采集的电源车输出电压数据进行分段和扩充处理;其次,基于仿真软件实现最小二乘法的数据拟合,并分析波峰系数;最后,采用航空电源车测试系统对电源车样机输出电压波峰系数进行实测。实验结果表明,仿真实验波峰系数为1.4285,实测波峰系数为1.42,仿真分析结果与实测结果基本一致,所研究的方法对大功率航空电源车的原理设计和样机制造起到一定的技术支撑作用。
The crest factor is an important index to evaluate the performance of the high-power aviation power supply vehicle.In this paper,a new crest factor analysis method combining parabolic interpolation method and least square method is proposed.Firstly,parabolic interpolation method is used to segment and expand the collected output voltage data of power supply vehicle.Secondly,the data fitting of least square method is realized under the simulation software,and the crest factor is analyzed.Finally,the crest factor of the output voltage of the prototype power supply vehicle is measured by the test system of the aircraft power supply vehicle.The experimental results show that the crest factor of the simulation experiment is 1.4285,and the measured crest factor is 1.42,and the simulation analysis results are basically consistent with the measured results.This research method plays a certain technical support role for the principle design and prototype manufacturing of high-power aviation power supply vehicle.
