Optimal Design for Bending Staff of Varying Section

Deng Changfu (Anhui Province Micro-Automobile Industry Co.)  
In this paper the volume function per unit length of the 26''-bicycles front fork is taken as the objective function. According to the conditions of geometric and, strength restraints, the feasible region is determined. The isoplethic lines of the volume function are drawn and the optimal design point is directly found with the graphic method. Therefore the goal of minimum freight of the beading staff structure is achieved. The weight of the optimal design structure is reduced by 16-19.6% of that of the original structure. It is therefore possible to improve the property and to raise the economic benefit of the product.
