摘要

Based on the Almen-Laszlo theory, this paper studies the mechanical properties of various kinds of disc springs used in ICV by theoretical calculation and finite element simulation. The mechanical properties of the disc spring group were also analyzed in this paper. The results show that the mechanical properties of elasticity and plasticity in the loading process are basically no difference, but there is a small difference between the theoretical calculation. With the positive valence of the number of disc reeds, the difference between the finite element and the theoretical results is more and more significant, but the trend is the same, and the finite element result curve is always above the theoretical curve. The effect of dislocation on the mechanical properties of disc spring group is that the fitting degree of finite element curve and theoretical curve decreases with the increase of dislocation, but there is always intersection point.
