Nonlinear Finite Element Analysis and Test of Lateral Loading for Two-Post ROPS
According to the structural characteristic and the test requirement of tow-post ROPS, a nonlinear finite element model of ROPS based on large-strain shell element was established, and the influence of elastic-plastic deformation of ROPS was taken into consideration. Then the computer simulation of ROPS was performed in lateral loading case, which obtained the deformation mode and the distribution law of equivalent plastic stress of ROPS followed by the discussion of deformation mechanism of ROPS. The simulation results accorded with test results. This paper can provide theoretical basis for the structural design of two-post ROPS.
