摘　　要：推导了并联式六维加速度传感器的基频、灵敏度的解析表达式。研究发现,基频与质量块的质量、压电陶瓷的厚度和直径有关,灵敏度与质量块的质量和边长有关。以这两项性能为指标,结合正交试验法和粒子群算法对上述参数进行优化。结果显示,最优性能下,质量块的质量、边长分别为0.7 kg,55 mm,压电陶瓷的厚度、直径分别为1.5,10 mm。最后,结合VB和SolidWorks软件,对球铰支链进行二次开发。Analytical expressions for fundamental frequency and sensitivity of parallel six-dimensional acceleration sensor is deduced.It is found by study that the fundamental frequency is related to the mass of the mass,the thickness and diameter of the piezoelectric ceramic,and the sensitivity is related to the mass and side length of the mass.Taking these two performances as optimization goals,the above parameters are optimized by combining orthogonal experiment and particle swarm algorithm.The optimization results show that under the best performance,the mass and side length of the mass are 0.7 kg and 55 mm,respectively,and the thickness and diameter of the piezoelectric ceramic are 1.5mm and 10 mm,respectively.Finally,Combining VB and SolidWorks software,the secondary development of the ball hinge is carried out.
