摘　　要：工作频带是加速度传感器的重要性能指标之一,但六维加速度传感器的最大工作频率目前尚不明确。鉴于此,分别以实心球体质量块型和空心球体质量块型六维加速度传感器为研究对象,构建了系统最大工作频率的数学模型。首先,通过虚拟实验,获得了传感器基频及最大工作频率与质量块直径和支链刚度之间的数据对。接着,分别绘制了基频和最大工作频率的性能图谱,并运用多元线性回归理论拟合了数据对。最后,运用线性包络原理建立了2个频率之间的映射关系。结果表明,最大工作频率始终介于基频的1/35~1/30区间内。Operation frequency band is one of the critical performance index of acceleration sensor.However,the maximum operation frequency of six-axis acceleration sensor is not clear at present.Given this,mathematical model for maximum operation frequency of the system is constructed,using solid spherical mass block type and hollow apherical mass block type six-axis acceleration sensor as research objects.Firstly,through virtual experiments,the data pairs between the fundamental frequency,maximum operation frequency and the mass block diameter and the side-chain stiffness are obtained.Subsequently,the performance atlases of the fundamental and maximum operation frequencies are depicted,and the multiple linear regression theory is used to fit the data pairs.Finally,the mapping relationship between the two frequencies is built by using the linear envelope principle.The results show that the maximum operation frequency is always within the fundamental frequency range of 1/35~1/30.
