Design of Isolation Membrane Based on Finite Element Method
At present,the theoretical formulas for studying the performance of membranes are mainly nonlinear algebraic equations.However,due to the large number of parameters,it is extremely difficult to study.Although the finite element numerical method requires a large amount of computation,with the continuous development of computer technology,the computational performance of computers can meet the requirements.By establishing a physical model of the isolation membrane and using Ansys FEM analysis software to simulate the deformation process of the membrane un-der uniformly distributed loads.By continuously adjusting the design parameters such as membrane thickness and ripple height,the center deflection and stress changes of the membrane are obtained.This method can greatly shorten the design cycle,improve design efficiency,and obtain more accurate design results.In addition,this method also reveals the deformation law and force characteristics of the membrane under different pressures through nonlinear bending analysis of the membrane's deformation under stress,which has certain guiding significance for the structural optimization and per-formance improvement of the membrane.
