【 摘 要 】

This paper presents simultaneous topology shape and sizing design of a walking-tractor handlebar based on using many-objective metaheuristics (MnMHs) in order to reduce vibration transmission, which to some extent causes vibration syndrome disease. The design problem is posed to maximise natural frequencies of the first 5 modes, minimise structure mass and minimise construction cost subjected to stress and displacement constrains with bending and torsion loading conditions. Design variables include topology of side bar stiffeners, shape, and size of all bars. Several MnMHs are used to solve the problems while the results are compared. With this study, the performances of MnMHs for solving optimum design of a walking-tractor handlebar is examined whereas the optimal structures are obtained.
