Mechanical Component Design: A Comprehensive Guide to Theory and Practice

Abstract

Any framework configuration decides the upsides of the plan boundaries to play out the predetermined assignments. The framework execution may fluctuate around its desired output due to uncertainties. Some of these uncertainties can be controlled while designing the system. The remaining uncertainties are not in control of the designer and are considered as noise. When the system is designed considering these uncertainties, the fluctuation around the desired output can be minimized. Robust design is a technique that ensures that the system will have minimum fluctuation around the desired performance affected by vulnerabilities. The powerful plan of system guarantees that the component will play out the predefined task under impact of vulnerabilities. In this research, a methodology for optimum robust design of mechanism is proposed and discussed, which designs optimum link lengths alongside the ideal connection length resiliences and ideal joint clearances. A technique for powerful plan improvement of component is proposed by considering the observations of parametric analysis of mechanism and robust design using the Taguchi method. The design parameters considered for robust design are all the link lengths, tolerance for all the link lengths and the joint clearances at the two closures of the coupler interface. The methodology is designed to work in loops, in the outer loop the optimization algorithm generated the population as a set of design parameters and in the inner loop, each set of design parameters from the population is analysed for robustness. In the proposed methodology, the joint clearance is considered as a clearance link. The orientation of the clearance link is considered in two ways, randomly orientated in the clearance circle and exactly determined by the dynamic force analysis.
