Examination of Lattice-like Structure for Vehicle Preliminary Design

Abstract

In this paper the examination of lattice-like structure is introduced. Lattice structures are built of crossmembers, side-wall and longitudinal beams. Both the crossmember and the beams can be symmetric, but the paper deals global symmetry of lattice. This global symmetry means a longitudinal and lateral symmetry plane of the structure. Similarly to the structure, the outer load can be symmetric or antimetric for these two symmetry planes, as well. The main purpose of this paper is to show reduction the number of the unknowns of the compatibility equation and predict the distribution of the bending moment in beams for practical use.
