Effect of cross-frame's relative stiffness on shipboard crashworthiness
Crashworthiness of civil aircraft has received increasing attentions over recent years and the drop and crash properties of aircraft can be improved greatly by appropriate crashworthiness design.
The real vehicle crash test indicates that the crashworthiness of the frame structure has improved apparently.
The safety design of the hydrogen bottles is an important factor in hydrogen energy vehicle crashworthiness.
In order to improve a mini-bus crashworthiness, firstly, a finite element method model was built.
The methods to evaluate the crashworthiness of the end structure of intermediate vehicles against side collision is described.
After carefully analyzing the bumper deformation and dynamic characteristics, Suggestions are given on how to improve the crashworthiness of the bumper.
The simulation results show that the original design has some problems with regard to crashworthiness. Some parts had inefficient energy absorbing characteristics and improper deformation mode.
In order to improve the crashworthiness of tramcar and LRV, the crashworthy structure of car-body is developed, and the verification by test is made.
As an example, the crashworthiness optimization of a body-in-white substructure consisting of front bumper and crash box of a car is carried out with good results achieved.
