Analysis of Energy Absorption in Cutting Processes of Roll-Over Protective Structure of Engineering Vehicle

Abstract:

Article Preview

This work is devoted to the development of a new type Rollover Protective Structure which absorbs the impact energy using shear energy absorber during a roll-over accident of engineering vehicles. A method is developed for investigate the energy absorption of the shearing processes using the finite element method coupled with the Cockroft-Latham fracture criterion, remeshing and element kill method accounting for nonlinear isotropic and kinematic hardening under the large plastic deformation. Comparing the simulation results with laboratory test results, the proposed method is valid. Using the finite element analysis method, the effects of shearing clearance, cross-section parameters and the shape of the shear edge on shear force and energy absorption of the process are investigated.
