Ω形波纹管圆环开口量对应力和刚度的影响

Effect of the Opening Size of Ω Shaped Bellows Toroid on the Stresses and Spring Rates

应用摄动初参数法分析了Ω形波纹管圆环开口量对各向应力最大值和单波轴向刚度值的影响。结果表明，对于理想圆环波纹管，其开口量可达到圆环的半径ｒ；对于椭圆圆环波纹管，其开口量亦不宜受０．

Abstract The effect of opening size of Ω shaped bellows toroid on various maximum stresses and axial spring rates per convolation by using perturbation initial parameter method is analyzed in this paper.The results show that the toroid opening size of Ω shaped bellows with ideal toroid can reach as much as the toroid radius,and the toroid opening size of Ω shaped bellows with elliptic toroid can be greater than half of the toroid radius.
