How to design compression spring
Spring, you should be familiar with it. It can be seen everywhere in our life. Spring can be found in many places, such as remote control, auto parts and other products. Spring is widely used, so it has many kinds. The following content will show you how to design a practical compression spring.
Parameters of compression spring
The parameters of compression spring include 6 items. First, let’s look at the meaning of each parameter;
- Material: the material selected for spring material;
- Wire diameter: material diameter of spring;
- Outer diameter: outer diameter of spring;
- Number of turns: total number of turns and number of turns of support rings at both ends
- Free length: length of body in free state
- Strength: When the spring has strength requirements, it is necessary to know the working height of the spring, that is, the specific strength of the spring when it is pressed (or pressed) to a certain length.
Analysis of force relationship of compression spring
After understanding the meaning of the above parameters of the compression spring, we will analyze the strength relationship of the compression spring, which is indispensable for designing a good spring.
- For springs with the same specification and size parameters, if only the spring wire diameter is changed, the spring force will increase with the increase of the spring wire diameter, and vice versa;
- For springs with the same specification and size parameters, if only the outer diameter of the spring is changed, the larger the outer diameter, the smaller the spring force will be, and vice versa;
- For springs with the same specification and size parameters, if only the number of coils of the spring is changed, the less the number of coils, the greater the spring force, and vice versa;
- For the spring under the same specification and size parameters, if only the free length of the spring is changed, the spring force will increase with the increase of the length, and vice versa.
The above is about the meaning of various parameters of compression spring and the factors that determine its elasticity
