摘要

基于一种新提出的并联式六维加速度传感器结构

从系统的正向动力学方程出发

构建了其灵敏度的数学模型

推导出灵敏度与结构参数间的映射关系。基于ADAMS软件对传感器进行参数化建模

并以灵敏度为优化目标

将仿真数值与理论计算的结果进行对比

验证了数学模型的正确性。结果表明:线加速度灵敏度主要受质量块的质量影响

角加速度灵敏度同时受质量块质量和边长影响

而外壳尺寸与灵敏度无关

且在空间三个正交方向的线加速度灵敏度和角加速度灵敏度均满足各向同性。

Abstract

Based on a new proposed parallel type six-axis acceleration sensor structure

mathematical model for sensitivity is constructed from the forward dynamics equation of system

and mapping relationship between the sensor sensitivity and structural parameters is deduced. Based on ADAMS software

the sensor is parameterized modeling and the sensitivity is optimized. The simulation value are compared with the results of theoretical calculation

and the correctness of the mathematical model is verified. The results show that the sensitivity of linear acceleration is mainly affected by the mass of the mass-block

and the angular acceleration sensitivity is affected by the mass of the mass-block and side length of the mass-block

and regardless of the size of the housing. The sensitivity of linear acceleration and sensitivity of angular acceleration in three orthogonal directions of the space satisfy the isotropy.
