Study on Structure Optimization Design for Outrigger of In-situ Slewing Device

Abstract

Abstract To solve the problem of insufficient turning radius for heavy-duty wreckers in narrow and congested road environment, this paper designed a new type of in-situ slewing device, and conducted a finite element simulation analysis on it. On this basis, by combining the optimization theory, this paper further optimized the structure of in-situ slewing device by using three different optimization design methods, including screening method, nonlinear second-order Lagrange method and quadratic integer sequence algorithm. The total weight loss of outrigger structure was 69.96 kilogram, the weight-loss ratio is equal to 7.34%. These results prove that the goal of structural optimization design has been achieved.
