![]() ![]() Rigid mechanisms can be characterized by a transmission ratio, which determines the displacement reduction and force amplification from input to output, for a conservative system. The motion diagnosis tool performs analysis that may prove useful in mechanism design. HexFlex compliant mechanism with loads (red) & fixed nodes (squares) brings up all the data associated with the current object and load state. Moments/forces can be super imposed and plotted to view combined loading responses. Figure 2 shows the analyzer interface in which a twisting moment (in the z-direction) is acting on a compliant ring. The analyzer plots the deformed response and presents analysis data. The thumbnail in the corner gives an alternate view at all times, facilitating three dimensional drawing. Within the editor, the user can also create, save, and retrieve files containing the mechanism geometry and parameters (material properties, boundary conditions, cross sections, etc.). cross sections and taper angles) and boundary conditions. The user creates a CoMeT model by drawing the compliant mechanism concept by hand (via mouse), setting material properties, structural attributes (i.e. The editor is similar to a basic CAD/drawing interface that emulates sketching by hand on paper. The CoMeT GUI is organized into five modules:įigure 1: CoMeT editor interface (user is Develop their engineering intuition about compliant mechanism.Obtain answers within 5 – 10 % of measured values.Test feasibility of design concepts (without time needed to build a CAD/FEA model, mesh, post process, etc…).The tool is targeted to provide a bridge between rough back of the envelope calculations (short, order of magnitude analysis) and detailed FEA (time consuming, accurate analysis). The software is designed to let a user quickly sketch an idea in a Matlab based GUI, then perform deformation, stress, optimization and sensitivity analyses of a concept. CoMeT is a tool for concept design of compliant mechanisms.
