| Abstract: | On the basis of the practical structure feature of a typical micro-structure silicon pressure sensing component. which is composed of multi layer different material, this paper establishes the math model between the measured pressure. static deflection and the basic naturalfrequency of the above sensing component. Moreover, the yaring laws of vibrating characteristics influenced by the geometric and material parameters of the every layers. were studied.And some useful results are provided. which may be given the theoritical basis for developingthe above pressure sensing component. |
