Abstract

Abstract: According to the preliminary design of the automatic plastering machine, the asymmetrical truss of traverse guideway needs to be lightweight and to reduce the deflection, torsional deformation and other issues.Using the combination of the professional steel finite element software Midas/Civil and two-factor non-repetitive experiment, deflection, torsional deformation and strength of asymmetric truss under static and constant load.Through the combination of different types of square steel pipe validation, get the automatic plastering machine supporting the truss structure.At last, the validity of the method is proved through experiments, and the truss’s flexural and torsional properties are improved while the weight of the truss is reduced.Professional steel analysis software to facilitate the use of the designer’s operation, improve work efficiency, automatic plastering machine truss design has an important reference value.

Key words: asymmetric truss, optimization, Midas/Civil, two-factor no repeat experiment, automatic plastering machine
