Abstract
Pedestrian protection technology has become the most important issue in the field of vehicle safety. The design and simulation method of pedestrian protection system for vehicles is studied based on the Teoriya Resheniya Izobreatatelskih Zadatch theory in this article. The optimal solution of a new type of all-around airbag system mounted to the front of vehicles is presented after performing some Teoriya Resheniya Izobreatatelskih Zadatch analysis tools, such as the component analysis, causal analysis, resource analysis, and contradiction analysis. The digital modeling is carried out on the airbag deployments by SolidWorks, and the simulation analysis is performed on the collision between vehicle and pedestrian head by HyperWorks and LS-DYNA. The results show that the vehicle equipped with the front-end all-around airbag than without can play a better role in pedestrian head protection during the collision, making the maximum value of head injury criterion decrease by 66.7%, effectively reducing the collision damage and verifying the feasibility of the solution.
Highlights
Nowadays, the scope of vehicle safety has been stretched from the protection of occupants in the vehicle to the protection of pedestrians outside the vehicle.[1]
This article presents a new type of all-around airbag system mounted to the front of vehicles aiming to improve the problem of pedestrian protection based on Teoriya Resheniya Izobreatatelskih Zadatch (TRIZ).[11]
The above simulation analysis and test results show that under the same conditions, the vehicle equipped with the front-end all-around airbag can play a better role in pedestrian protection during the collision, which make the maximum value of head injury criterion (HIC) decrease by 66.7% and effectively reduce the collision damage
Summary
The scope of vehicle safety has been stretched from the protection of occupants in the vehicle to the protection of pedestrians outside the vehicle.[1]. This article presents a new type of all-around airbag system mounted to the front of vehicles aiming to improve the problem of pedestrian protection based on Teoriya Resheniya Izobreatatelskih Zadatch (TRIZ).[11] This solution considers the materials and installation position of the airbag and designs the control device and elastic device of airbag.
