| Abstract: | In this paper, a limit speed mathematical model of elastic deformation, plastic deformation and flow deformation of the FOPS shell was established. We investigated the impacted dynamic response of a thin plate and established a maximal displacement mathematical model of the impact center. It laid the theoretical foundation for rational design of FOPS. Further more, we gave an anti breakthrough capability test of the wheel loader ZL50G FOPS,and calculate the exciting force on both the drop hammer and the crossbeam of the FOPS. We found that the FOPS top surface of wheel loader produced plastic yield and non linear response while being impacted by drop hammer. |
