Rollover accidents of engineering vehicles easily happen, especially in the harsh working environments or on the bumpy roads. ROPS is an effective method to reduce casualty rate in rollover accidents. This paper designed a safety-cab ROPS by joint strengthening method for a large-type wheel loader. The finite element model of this ROPS, which is together with the rear frame, absorbers and supporting structures of the safety-cab, was created. Boundary conditions of forces and displacements were obtained according to international standard ISO3471: 2008. The large elastic-plastic deformation finite element analysis of ROPS was performed in the lateral, vertical and longitudinal loading cases and the corresponding laboratory performance tests were conducted. The results show the designed ROPS can meet the requirements of ISO3471: 2008. The results difference between tests and simulations and the weld fracture reasons for the ROPS joints were analyzed.
