A New Design of High Impact Load Rejection System Based Mechanical Linkages Using the Self-Restitution Mechanism

This paper presents the development and characterization of a new design based on mechanical linkage for impact rejection mechanism. It works by transforming the input force into the desired output force through the movement of mechanical linkage in a series direction. The proposed mechanism consists of receiving plate, input link, coupler, counter link, and spring based link to counter the receiving force to the system. The work consists of mathematical modeling of the mechanism using Lagrange Equation in order to predict the behavior. The model is then simulated within MATLAB/SIMULINK environment to evaluate the functionality of the mechanism. In order to represent the input force, experimental data of the impact force for a pendulum impact is used in simulation. The simulation acts as a proof of concept for this mechanism in reducing impact force acting on it. Further simulation is done to characterize the mechanism by applying various impact loads. In conclusion, it is proven that the mechanism is able to transform the input force into the desired output force while simultaneously dampening the force.
