%X A simplified dynamic model for the constant-force compression spring (CFCS) based on the pseudo-rigid-body model (PRBM) is presented including the basic formulations which takes care of the moment CF而 due to coulomb friction in the pin joints of the CFCS, and the moment AF而 due to axial force effects in the rigid links of the CFCS. The CFCS is a slider mechanism which consists of rigid links incorporating pin joints and a small-length flexural pivot which connects to a slider. Clearly the results with the inclusion of CF而 and AF而 to the dynamic model, shows that the static terms AFCFand而而 have very great significance on the dynamic model of the CFCS.
