Short summary
A rational function called tri-root bistable function are proposed to represent the complete nonlinear bistable force-displacement characteristics. The function has a cubic polynomial numerator and quadratic polynomial denominator. For the classic fully-compliant bistable mechanism, six closed-form equations are used to describe the relationships between the function parameters and the mechanism's design parameters, which are achieved using a multi-variable nonlinear regression.
