The elastic coefficient of a spring refers to the elastic force generated by the spring under unit deformation, also known as the spring constant or stiffness coefficient. The elastic coefficient is an important indicator to describe the performance of a spring, which directly affects the use effect and life of the spring.
Definition and influencing factors of the elastic coefficient
The elastic coefficient is defined as the ratio between the elongation or compression of the spring and the external force it is subjected to.
Among them, (F) is the external force on the spring, and (\lambda) is the deformation of the spring. The larger the elastic coefficient, the harder the spring, and the greater the elastic force generated under the same deformation. 1.
Factors affecting the elastic coefficient of the spring include:
Material: The elastic modulus of the spring material directly affects the elastic coefficient.
Wire diameter: The larger the diameter of the spring wire, the larger the elastic coefficient.
Number of turns: The more effective turns of the spring, the smaller the elastic coefficient.
Outer diameter: The larger the outer diameter of the spring, the smaller the elastic coefficient.
Free length: The free length of the spring also affects its elastic coefficient.
