An experiment for investigating the force required to achieve maximum deflection of different stacking arrangements of disc springs, along with the spring rate. It fits in the Universal Testing Machine (SM1000) and consists of disc springs, a spring guide and a compression cylinder.
Disc springs are common in many industries. The main applications are those that require a small deflection for high force levels. Disc springs can easily be stacked in a variety of arrangements to vary their deflection rates.
The disc guide is fitted to the lower compression pattern and the compression cylinder to the upper pattern. The disc springs are stacked in the desired combination on the disc guide. The SM1000 pump is operated to raise the ram and compress the springs.
The spring discs can be stacked in parallel, in series or in a combination of series and parallel.
