摘　　要：采用有限元方法计算了弹簧丝直径为13mm的圆截面和长短轴相差±0．1mm的椭圆截面的圆柱螺旋弹簧受到的等效应力和剪切应力。结果表明，将弹簧丝直径的精度控制在±0．1mm以内对弹簧受到的应力影响不大，能够满足使用要求。The equivalent stress and shear stress of Ф13 mm circular section springs and ellipse section springs which have 0. 1 mm longer of the long axis than the short one, were calculated through the FEM method. The result shows that controlling the circle spring section diameter error within 0. 1 mm has little influence in the spring stress, and the using requirement can be met.
