Abstract—A mathematical dynamic model is derived for the compliant constant-force mechanism, based on the pseudo-rigid-body model simplification of the device. The compliant constant-force mechanism is a slider mechanism incorporating large-deflection beams, which outputs nearconstant-force across the range of its designed deflection. The equation of motion is successfully validated with empirical data. The dynamic model is cast for one out of 28 possible configurations of compliant constant-force slider crank mechanism, identified by type synthesis techniques (Howell, 2001). The author derived the dynamic model through Lagrange’s Equation for the selected configuration of compliant constant-force slider crank mechanism. An unexpected dynamic trait of the constant-force mechanism is discovered: there exists a range of frequencies for which the output force of the mechanism accords nearer to constant-force than does the output force at static levels.
