“…2 The concept of pedestrian protection for vehicles was put forward in the 1960s. Many scholars have studied the traffic accidents and adopted pedestrian impactor model to carry out collision analysis by means of software modeling and test simulation on pedestrian head, calf, and thigh, 3,4 then more effective pedestrian protection measures are put forward. [5][6][7] At present, there are four kinds of pedestrian safety protection devices for vehicles: the optimized and improved bumper, 8 the pop-up engine hood, 9 the pedestrian airbag protection system, and the intelligent vehicle safety system.…”

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.
