Studying on the design and simulation of collision protection system between vehicle and pedestrian

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.

Trends and characteristics of severe road traffic injuries in children: a nationwide cohort study in Japan

“…In urban areas in particular, pedestrians and traffic volumes are large, and past reports have shown that important risk factors related to pedestrian crash risk include the number of bus stops per unit time, parking spaces, crosswalks, frequency of violations, variations in traffic speed, and number of intersecting side roads, in addition to through and intersecting traffic volumes [29] The design of roadways and the development of various land uses can both increase and decrease pedestrian traffic crash injuries, and urban and regional planners need to design the built environment to minimize pedestrian risk [30]. Widespread use of automatic braking systems to reduce the speed of vehicles in collisions could also reduce serious traffic trauma for pedestrians [31]. Severe traffic trauma while walking was particularly high in this study, especially among 0-5 and 6-11 year-olds, and interventions will have to be made to encourage safe pedestrian behavior in the patients themselves and their families [32].…”

A branching algorithm to reduce computational time of batch models: Application for blast analyses

“…This includes vehicle design and safety assessments (e.g. Lu et al, 2020; Wu et al, 2020), search and rescue tools (e.g. Coppini et al, 2016), pressurised water pipe failure (e.g.…”

Pedestrian Head Impact Analysis on a Vehicle and Measures to Reduce HIC Value

“…In an all around planned vehicle, the body and different parts are the defensive layer for the tenants of the vehicle. The accessibility of elite execution PCs and crash reproduction programming has upset the interaction (7). Mishap crash insights, biomechanics, unofficial laws, and public area front facing security tests will be surveyed (8).…”
