Introduction to Coil Spring
A coil spring, also known as a helical spring, is a mechanical device which is typically used to store energy and subsequently release it, to absorb shock, or to maintain a force between contacting surfaces. It is made by winding a wire around a cylindrical or conical form in a helical shape. Coil springs are widely used in various industries, including automotive, aerospace, furniture, and machinery. In the automotive industry, for example, coil springs are an essential part of the suspension system, providing a smooth ride by absorbing the shocks from the road surface.
