Dynamic Behavioral Model Development for Constant-Force Compression Spring Electrical Contacts

Abstract

This research work explores the usefulness of the pseudo-rigid-body model (PRBM) in the dynamic behaviour analysis of constant-force compression spring electrical contacts (CFCSECs). It also expresses the desire to understand how CFCSECs behave dynamically. Such knowledge is important in the implementation of CFCSECs in viable commercial applications. The relative simplicity of employing the PRBM to streamline the dynamic analysis of CFCSECs, compared with existing dynamical methods, combined with the fact that the dynamic model can be represented mathematically, is a large step forward. Results obtained for these CFCSECs revealed a very important phenomenon of the peak-to-peak force plot, that over certain range of frequencies, these mechanisms exhibit better constant-force behaviour than they do statically
