压电式六维加速度传感器输入输出特性研究

摘要/Abstract

摘要：

针对目前六维加速度传感器普遍存在解耦过程复杂、计算效率低的现状，在ADAMS软件中对已有的一种压电式六维加速度传感器进行建模研究，分析不同驱动条件下传感器的输出特性，探究在该压电式传感器解耦过程中忽略动平台相对于静平台的运动对传感器解耦计算效率及精度的影响，并绘制出理论输出误差与加速度输入量中线幅值、线频率、角幅值和角频率间的关系曲线。研究表明：解耦计算时忽略该传感器动平台相对于静平台的运动会引入一定的误差且该误差取决于加速度输入量，当输入量满足一定条件时，通过简化解耦算法得到的加速度与简化前的解耦算法所得的加速度相比,所引入的额外误差不超过0.2%，而计算速度可提高2倍。

Abstract:

Six-axis accelerometers based on parallel mechanisms generally have complex decoupling processes and low efficiency. In view of this situation, a model of an existing six-axis piezoelectric accelerometer was bulit in ADAMS and the model was used to study the characteristics of the output in different inputs, to study the effects of the motion of the moving platform relative to the static platform on the calculation efficiency and computational accuracy and to plot some curves to show the relationship among the errors and the linear amplitude, linear frequency, angular amplitude and angular frequency of the input of the acceleration. Based on the research, an additional error will be brought in if the motion of the moving platform relative to the static platform was ignored during the decoupling process and the error mainly depended on the input of the acceleration. As long as the input of the acceleration satisfied the given requirements, the simplified decoupling processes can be used to solve the acceleration,and the additional error will be less than 0.2% while the calculation velocity will improve about 2 times.

Key words: six-axis accelerometer, decoupling, calculation efficiency, error
