Abstract：For improving the impact resistance performance of the suspension crossing frame, the hydraulic energy absorption device suitable for the crossing frame is designed based on the load-bearing characteristics of the suspension crossing frame under the accident state, and the energy absorption effect verification test is carried out. Firstly, based on the analysis of the load-bearing characteristics of the suspension crossing frame under accident conditions, several different types of energy absorption principles are compared, and finally the hydraulic energy absorption device is selected for design. Then, the energy absorption effect of the energy absorption device is tested through the small-scale vertical state test of the load-bearing cable of the suspension frame. The result shows the energy absorption effect of the hydraulic energy absorption device is 71.05%. In order to further verify the energy absorption effect of the energy absorption device under real working conditions, the large-scale impact test technology is carried out, and the impact response law of the load-bearing cable with and without energy absorption device is tested. The experimental results show that under the conditions of 110m span, 0.5T heavy load and 0.5m impact height, the energy absorption effect of the hydraulic energy absorption device reaches 32.10%, which can effectively improve the impact resistance of the suspension type crossing frame.
