| Abstract: | In this paper,a cowcatcher with hight security is provided by taking the opportunity of developing the type HXD1 G eight-axle AC drive fast passenger electric locomotive and analyzing the requirements of EN 15227.The finite element calculation is performed to guide the subsequent system tests.Both the simulation results and the test results show that the cowcahtcer can withstand 300 kN compressive load while the load is applied to the center line of cowcather,and the cowcatcher also can withstand 250 kN compresssive load while the load is acted on the 750 mm lateral distance from the center line.The structural strength of cowcatcher can meet the requirements of EN 15227. |
