Parametric Deflection Approximations for End-Loaded, Large-Deflection Beams in Compliant Mechanisms

Abstract: Geometric nonlinearities often complicate the analysis of systems containing largedeflection members. The time and resources required to develop closed-form or numerical solutions have inspired the development of a simple method of approximating the deflection path of end-loaded, large-deflection cantilever beams. The path coordinates are parameterized in a single parameter called the pseudo-rigid-body angle. The approximations are accurate to within 0.5 percent of the closedform elliptic integral solutions. A physical model is associated with the method, and may be used to simplify complex problems. The method proves to be particularly useful in the analysis and design of compliant mechanisms

Compliant constant-force mechanism and devices formed therewith

Abstract: A compliant mechanism is configured to generate a substantially constant output force in response to an input in the form of a linear displacement. The compliant mechanism is a slider mechanism whose members and their interconnects cooperate to generate a biasing force that causes the slider mechanism to generate a substantially constant output force that is substantially parallel to the linear path of a reciprocable member in response to the displacement of the reciprocable member along the linear path. To achieve the above functional characteristics, the slider mechanism is composed of structural elements, one or more of which is compliant.
