The Optimal Design of Composite Bead Wire Saw Frame Based on SUMT

Composite (multiple) bead wire is an important machine for stone-sheet production with efficiency, but it takes up space, with big energy consumption, uneven thickness, and noise. The current study aims at optimal designing a bead saw with energy-, material-saving, and being light in weight under the constraint of the strength, stiffness and stability for the frame. A 140 rope saw, as a prototype and one of the applications, discussion of two main frames were done with the layouts consisting of the driving wheel, guide wheel, and the supporting wheels from a variety of structural Patterns. By comparison between the triangular and rectangular layouts, a conclusion was drawn that under the condition of all other things being equal, rectangular layout is more reasonable; each wire is supposed to be adjusted for the uniformity of tension of the whole wires. The objective function was taken as the sum of the mass expression of each component of the frame with a series of punishing factors. The hollow structure of double columns with guide grooves and special beams were got, achieving design goals.
