Belleville Washer Hysteresis
Friction may cause the actual measured load versus deflection for a stack of Belleville springs to be different than the calculated values. In a bolting system, there are several measurable locations of friction that can occur between parallel stacked springs, between the loading surfaces, and between the guiding surface of the springs in the stack.
This white paper discusses the frictional hysteretic phenomena that can occur within a bolting system, correlating to a loss of energy and reduced performance. The magnitude of hysteresis can be affected by several factors such as surface roughness, lubrication, component materials, hardness of components, number of springs in parallel and series, etc. For bolted joints, it is ideal for the hysteresis to be as small as possible. In order to evaluate the effectiveness of options, it is necessary to compare load curves using different components, treatments, techniques, etc.
