| Abstract: | In order to improve the terminal part of a removeable barrier,a rectangular pipe type framework was developed using finite element simulation method refer to crash test data.The results indicate that the framework can withstand 1.1 times test loading,it is much more excellent performance,easier to process and material consumption can be reduced 21% compared to original design structure.The structure meet the application requirements and have been implemented successfully in project. |
