Analysis of Micro Structure’s Elastic Stiffness Shen Li1,a, Gao Shiqiao2,b, Jiang Anran 3,c, Wang Caifeng4,d 1,2,3,4State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing 100081, China ajie_shenli@163.com, bgaoshq@bit.edu.cn,cjianganran@sina.com,drudygey@126.com Keywords: micro gyroscope, beams, stiffness, ANSYS Abstract: Based on the calculation and analysis of three kinds of elastic beam’s stiffness coefficient in micro machined gyroscope, the results show: in the condition of small displacement, forces and displacement are linear relationship in clamped-clamped beam, crab-foot beam and bow beam; but as the displacement increases, the relationship between forces and displacement are obvious non-linear in clamped-clamped beam.
In such scale, certain characteristics of material which are frequently neglected will have a significant influence on the performance of MEMS[5,6].
