| 摘 要： | 在对衬垫材料进行冲击特性的实验研究时，测量所获得的波形常含有零点偏移，零点偏移的存在将对实验结果相入不可忽略的误差。因而在数据处理时应首先对零偏进行补偿以提高测量精度。本文作者根据在实测波形特征分析和能量原理基础上所建立的补偿方法，将现代控制理论中的模型参考自适应原理用于冲击信号的零点偏移补偿，拟定了模型参考自适应算法，给出了参考模型的建模途径，并编制了应用软件，支实验数据进行零偏补偿，取得了满意

| Abstract: | There is usually zero shift in shock waveforms obtained in experimental study on absorption properties of cushion materials.It is necessary to remove the zero shift before data processing,so as to eliminate errors that may happened.Based on waveform features and energy analysis,model reference adaptive theory is introduced into the compensation of zero shift mentioned above,and a model reference adaptive algorithm is presented by the author.Models of prototype shock waveforms are discussed in detail.A compensation software is developed and used in data processing.Fine results are obtained. |
