Spring stiffness is the ratio of load increment dF and deformation increment d λ, that is, the load required to produce unit deformation, spring stiffnessCalculation formulaF&# 39=dF/dλ。For the spring whose characteristic line is an increasing type, the stiffness increases with the increase of load;The stiffness of the decreasing spring decreases with the increase of the load.As for the linear spring, the stiffness does not change with the load, that is, F&# 39=DF/d λ=F/λ=constant.Therefore, for a spring with a linear characteristic line, its stiffness is also calledSpring constant。
Chinese name
Spring stiffness
The stiffness of the spring is
Ratio of load increment dF to deformation increment d λ
The calculation formula is
F'=dF/dλ
T ---
Torque for the torsion spring
Terminology
1. The deformation of the spring caused by the unit force, that is, the reciprocal of the stiffness is called the spring'sflexibility。
2. Calculation: spring stiffness refers to the load that causes unit deformation of the spring, and C and CT are used to represent the stiffness andTorsion springThe stiffness of theexpressionAs follows:
For tension spring
Where: F --- SpringaxialTensile (compressive) force;λ --- axial elongation of spring orCompression amount；
