How Deflection Range Affects the Performance of Disc Springs

PublishTime：2022-11-07

●Disc Springs are conically shaped washers designed to provide predictable and repeatable performance. They may be used to either apply a static load, where the load is nearly constant, or in dynamic situations, where the Disc Spring is experiencing repeated loading and unloading. It is critical to understand how load characteristics affect performance to properly design a system that uses Disc Springs.
●Springs are unlike other assembly components; they are designed to deflect and store mechanical energy. The deflection of a Disc Spring is predictable, making it possible to estimate the life cycle of a Disc Spring in an assembly.
●Optimal Disc Spring performance is achieved when working deflection is kept between 15% and 75% of full deflection. It is in this range that measured results most accurately match the theoretical characteristics of Disc Springs.
●The measured characteristic curve in the lower range (less than 15% of full deflection) departs from the theoretical curve due to residual stress. In the midrange of the curve, corresponding to the normal working range of the Disc Spring, the measured and theoretical characteristics are very similar. As deflection increases beyond 75% of full deflection, the force moment arm is reduced and deviation from theoretical characteristics rapidly increases. It is for this reason predictability of force/deflection is restricted to the normal operating range of the Disc Spring.
