Kinematic Analysis of compliant slider Crank mechanism

Abstract This study presents the design and formulation of a kinematic model of a compliant slider-crank micro mechanism and its comparison with the conventional slider-crank mechanism. This work aims with Experimental Analysis of Compliant Slider Crank Micro Mechanism for kinematic performance with a parametric variation. In addition, it also deals with the study of the Mechanical advantage of compliant micro mechanisms. A formulated model is developed using the pseudo-rigid-body model (PRBM). Motion analysis software is used to show the variation in slider displacement for known input link angle. Analysis of compliant mechanism is modeled by PRBM and FEA to analyze deflection. The mechanism is modeled in Adams. The results obtained from Adams are compared with experimentation. The displacements are fairly matches to simulation results. Better displacement as compared to rigid link mechanism can be obtained for smaller angular rotation. Finite element analysis (FEA) is used to show the stress distribution inflexible component for various types of hinges like rectangular cross-section flexible hinges, circular cross-section flexible hinges. Based on stress fatigue analysis is carried for both type joint by experimentally and FEA.
