摘要：Link Design plays important role in lifting machines. Links connected with pins will extend andcontract during operation. So operation length is an important parameter in the design of Link mechanisms. Due to theadvances in computer based Finite Element softwares, multi-body simulation provides good flexibility for the designerto choose better link mechanism satisfying. This type of simulation eliminates the need of prototype modelling andtesting by which production cost will be less and design cycle time also reduces due to the flexibility of easier testing ofnumber of mechanisms with in short time.In the present work, a single lever Grab tong is designed and analysed for structural strength. Initially theoreticalcalculations are carried out to check the minimum dimensions required for the problem. Later three dimensional cadmodelling is carried out and structure is meshed with two dimensional and three dimensional elements. Designoptimization is carried out to reduce the weight of the structure using computer simulation. Design optimizer a tool inANSYS helps in fast optimization satisfying the functional requirements. Totally 26 sets are obtained which satisfy thefunctional requirements. The results are obtained for the best set also along with the graphical plots showing influenceof design parameters on the structural weight of the single lever tong. Finally all the results are represented withnecessary pictorial plots.
