Optimization Design for Crank Arc Guide Bar Gathering Mechanism of Crab Claw Type Loading Machine

Abstract:

This paper conducts a comprehensive study on the optimization design for crank arc guide bar gathering mechanism of crab claw type loading machine. The optimization aim is to make reality locus of gathering claw end-point be as in-accordance as possible with ideal locus, and so on. Formulae are derived for displacement of gathering claw end-point and position angle of the gathering claw. An optimization design model is established for the crank arc guide bar gathering mechanism. The crank arc guide bar gathering mechanism is optimized of crab claw type loading machine with 2100 mm wide, and the optimization result is satisfactory. Compared to the optimized crank straight line guide bar gathering mechanism in literature [2], the locus error function of gathering claw end-point has been largely improved with a reduction of 25.8%.
