This paper built the 100% frontal crash model of minibus, 8 thickness components which have obvious effect on vehicle performance were selected as design variables, and choose appropriate evaluation index responses. Use DOE experimental method to get 70 set training data Kriging approximate based data. The is optimized by PSO algorithm, in scheme, amax m has decreased 7.6% 0.87%, D1, D2 D3 7.7%...

tic perception. Even though modern petrol cars are very quiet, a higher crashworthiness has not occurred so far. By installing artificial sounds one of the main advantages of electric vehicles, soundless driving, would be destroyed. This article by the University of Duisburg-Essen experimentally traces the potential risk of danger and tries to propose solutions. SoUnD PErcEPTion of ElEcTric VEh...

This study investigated the effects of pneumatic fenders on prevention structural damage from collisions between a ship-shaped offshore installation and shuttle tanker during side-by-side offloading operations. A nonlinear finite element modelling technique was developed to simulate kinetic energy absorption behaviour collisions. Full-scale were physically tested validate computational model at...

Hierarchical structures are widely observed in nature, and they have been considered to excellent mechanical properties. In this paper, a novel hierarchical honeycomb with graded design is proposed improve impact resistance. Two parameters selected determine the of hierarchy gradient respectively. A series nonlinear finite element models developed Abaqus systematically explore crashworthiness. ...

Since 1 990, Monash University Accident Research Centre has conducted a series of studies to provide consumer advice on the crashworthiness of individual makes and models of Australian passenger cars. Crashworthiness has been defined as the relative safety of a vehicle in preventing severe injury to its driver when involved in a crash. A concept complementary to crashworth iness is vehicle aggr...

This paper proposes a total-system design methodology that includes four important components necessary for a systematic approach to oil tanker concept design. These are: • An efficient and effective search of design space for optimal or non-dominated designs • Well-defined and quantitative measures of objective attributes, cost and risk • An effective format to describe the design space and to...

Consumer crash test programs provide comparative information on the crashworthiness of new vehicles which, in turn, should predict the performance of the same vehicles in real-world crashes. However, the detail and quality of available information from tests and real-world crashes differ widely, so identifying meaningful relationships between crash test results and real-world crashworthiness ca...

This work studies the potential of using wooden tubes for crash applications. The were made from 1 mm thick “I214” poplar veneers, according to different stacking sequences. Four configurations characterized under static crushing (5 mm/min) and one that performed best ([90/04/90]) was chosen undergo dynamic tests a drop weight tower (5.7 m/s). configuration presents significant energy absorptio...

Parametric design optimization of an automotive body crashworthiness improvement is presented. The thicknesses of parts are employed as design variables for optimization whose objective is to increase the maximum deceleration value of the vehicle center of gravity during an impact. Using the Taguchi method, this study analyzes the optimum conditions for design objectives and the impact factors ...
