Flat springs and circular springs are common mechanical elastic components that are widely used in industries, automobiles, machinery, and other fields. So, which is better, flat spring or round spring? Let's explore below.

Firstly, the structure of flat springs and circular springs is different. Circular springs are made by bending circular steel wires, while flat springs are made by cutting and bending flat steel plates. Due to the larger cross-sectional area of the flat spring, its deformation under the same load is smaller and less prone to deformation, resulting in better stability.

Secondly, the application scenarios of flat springs and circular springs are different. Circular springs are usually used in situations with light loads and small deformations, such as clocks, instruments, electrical appliances, etc. Flat springs are suitable for situations with large loads and deformations, such as automobiles, construction machinery, railway vehicles, etc.

Once again, the advantages and disadvantages of flat springs and circular springs are also different. Circular springs have the advantages of simple structure, low manufacturing cost, light weight, and easy installation, but they are prone to deformation and have a short fatigue life when subjected to large loads. Flat springs, on the other hand, have the advantages of bearing large loads, small deformation, long fatigue life, and high reliability, but they have high manufacturing costs and complex installation.

Finally, the selection of specifications for flat springs and round springs also needs to be noted. The selection of specifications should take into account factors such as application environment, load requirements, and process requirements to ensure that the spring has good elasticity and durability during operation.

In summary, flat springs and circular springs have their own advantages and disadvantages. When selecting, it should be based on specific application scenarios and requirements to achieve better results.
