Optimal Synthesis of Four‐bar Linkage Path Generation through Evolutionary Computation
2 Sustainable and Infrastructure Research and Development Center, Department of Mechanical Engineering, Faculty of Engineering, KhonKaen University, KhonKaen City, Thailand ABSTRACT: This paper presents the optimization of path generating of four-bar linkages using evolution algorithms (EAs). The design problem is assigned to minimize the error between desired and obtained coupler curves. Such ...
متن کاملFour-Bar Linkage Synthesis Using Non-convex Optimization
We show how four-bar linkages can be designed using non-convex optimization techniques. Our generative design software takes as input a curve that needs to be reproduced by a four-bar linkage and outputs the best assembly that approximates this curve. We model the problem using quadratic constraints and show how redundant constraints help to solve the problem. We also provide an algorithm that ...
متن کاملParametrization-Independent Non-Uniform Fourier Approach to Path Synthesis of Four-Bar Mechanism
This paper deals with the classical problem of dimensional synthesis of planar four-bar linkages for path generation. Using Fourier descriptors, a given path is represented by harmonic series. Extensive research has been done on this approach in mechanism synthesis with the assumption that the path is assigned a prescribed parametrization or timing beforehand, and the input link of mechanisms r...
متن کاملMore Effective Optimum Synthesis of Path Generating Four-Bar Mechanisms
The one-phase synthesis method using evolutionary or heuristic optimization algorithms can successfully solve the dimensional synthesis problems of path generating four-bar mechanisms discussed in the literature, where the input angles are usually used as design variables and the constraint of the rotational sequence of the input angles is necessary. However, there is still room for improvement...
متن کاملDimensional Synthesis of Four Bar Mechanism Using Genetic Algorithm
The dimensional synthesis is done by using Genetic Algorithm to achieve a desired trajectory. Three problems are analyzed having different curvature. The program is authored in MATLAB ® 2010a. The error is seen to be in the permissible prescribed limit. The prototyping of straight line trajectory analysis is also done in ADAMS ® .
