Finite Element Analysis of Diaphragm Type Air Springs considering the Variation of Fiber Angles

섬유의 적층각을 고려한 다이아프램형 공기 스프링의 유한요소 해석

this paper concerned with the stress analysis of a diaphragm-type air spring which consists of rubber linings nylon reinforced rubber composite. The analysis is carried out with a finite element method developed to consider the orthotropic properties geometric non-linearity and contact between an air bag and a bead ring The material properties are evaluated with the Halpio-Tsai equations and the rule of mixture. The analysis results demonstrate the variation of the outer diameter the fold height and the vertical force with different models to the design a proper diaphragm air springs.
