Robust Design of 4-Position Motion Generation and Application on Front End Loader

Abstract

A robust design approach of 4-position motion generation is presented, and it is applied in the design of front end loader. The mathematical model of optimum design based upon the engineering requirements has been established, by which feasible robust solution regions adhering to conventional constraints and kinematic accuracy requirements can be visually represented. It guides designers to synthesize robust mechanisms that ensure every design condition. The example of front end loader demonstrates that the process of searching the optimal robust mechanism is more intuitive, highly accessible and easy to be applied in engineering practice.
