Alternative Constraint Handling Technique for Four-Bar Linkage Path Generation

Abstract

Abstract. This paper proposes an extension of a new concept for path generation from our previous work by adding a new constraint handling technique. The propose technique was initially designed for problems without prescribed timing by avoiding the timing constraint, while remain constraints are solving with a new constraint handling technique. The technique is one kind of penalty technique. The comparative study is optimisation of path generation problems are solved using self-adaptive population size teaching-learning based optimization (SAP-TLBO) and original TLBO. In this study, two traditional path generation test problem are used to test the proposed technique. The results show that the new technique can be applied with the path generation problem without prescribed timing and gives better results than the previous technique. Furthermore, SAP-TLBO outperforms the original one.

High-Lift Mechanism Motion Generation Synthesis Using a Metaheuristic

“…The trigonometric relations are used for position analysis of the four-bar linkage. The relation is in form of linkage lengths r1, r2, r3, and r4 and other parameters, which are commonly found in standard mechanics of machinery textbooks as mentioned in [6][7][8].…”

“…A four-bar linkage is a common mechanism used in many machines that are included a windshield wiper, a door closer, a rock crusher, an oil well, HLM etc. Fundamental design of this mechanism is classified as function generation, path generation [5][6][7][8][9][10][11][12][13][14] and motion generation [12][13][14]. In this research, we adapt the previous techniques in group of the motion generation problem [12][13][14] to study the mechanism synthesis of HLM.…”
