    随着压缩弹簧压缩过程中载荷的增加,弹簧材料的表面剪切应力逐渐增 大,直到超过材料的弹性并发生塑性变形,并在接近弹簧的位置逐渐达到材料的弹性极限。核心。材料外层的塑性变形效果无法完全恢复到其原始状态,从而导致残余变形。

    With the increase of load in the compression process of compression spring, the surface shear stress of the spring material increases gradually until it exceeds the elasticity of the material and plastic deformation occurs, and gradually reaches the elastic limit of the material near the spring. The core. The plastic deformation effect of the outer layer of the material can not be completely restored to its original state, resulting in residual deformation.

    如何确定弹簧在强压处理下的压缩量?

    How to determine the compression of spring under strong pressure treatment?

    当这种弹簧起作用时,材料核心处的应力会增加,而表面处的应力会减少。应力的这种变化可以充分发挥材料的潜力。普通弹簧通常在设计时会考虑弹簧的极 限变形,并且不会超过弹簧的限应力。材料的不同容许剪切应力,弹簧的不同载荷类型以及不同的容许弹簧应力。

    When the spring works, the stress at the core of the material will increase, while the stress at the surface will decrease. This change of stress can give full play to the potential of materials. The limit deformation of ordinary spring is usually considered in the design, and it will not exceed the limit stress of spring. Different allowable shear stress of material, different load type of spring and different allowable spring stress.

    具体计算可以基于轴向载荷下弹簧变形和剪应力的计算公式。如果小于极限值,则可以压缩弹簧。如果大于极限值,则极限值为大压缩量。超过极限值将导致变形。

    The specific calculation can be based on the calculation formula of spring deformation and shear stress under axial load. If it is less than the limit value, the spring can be compressed. If it is greater than the limit value, the limit value is a large amount of compression. Exceeding the limit value will cause deformation.
