Question Spring Newbie 2017/11/1(Wed) 8:32

I have heard that conical coil springs have non-linear characteristics. What are the spring characteristics of a general conical coil spring when you illustrate them into graphs?

Answer Tokai Spring 2017/11/1(Wed) 8:42

Spring Newbie, the spring characteristics of conical coil springs are similar to those shown in the attached graph.
The load is weak at the beginning of deflection, and then gradually rises. I will attach reference materials for the diagrams here.
