The dynamic behavior of a body-in-white (BIW) structure has significant influence on the noise, vibration, and harshness (NVH) and crashworthiness of a car. Therefore, by improving the dynamic characteristics of BIW, problems and failures associated with resonance and fatigue can be prevented. The design objectives attempt to improve the existing torsion and bending modes by using structural op...

This article presents an application of data mining method on finite element data and crashworthiness result data of an occupant restraint system. According to the characteristics of the CAE (Computer-Aided Engineering) data, a framework for data preparation is developed based on object-oriented programming concepts. Training sets are built from data recorded in 98 crash simulations that adhere...

Offshore installations are designed to withstand against potential collisions from offshore supply vessels (OSV). Quantitative risk assessment (QRA) provides an overall picture of expected collision frequencies and consequences for the design life a platform subsequently estimates damage repair cost. However, main challenge QRA study is how well various uncertainties implemented into model. Thi...

The increasing use of composite materials in the automotive field requires more attention with regards to appearance noise, vibration and harshness (NVH) study cars construction. However, car door panels production, impact characteristics need be evaluated sandwich laminates. Furthermore, it is important consider effect prolonged environmental aging on crashworthiness properties. innovative con...

STUDY OBJECTIVE We assess the relationship between steering wheel deformity and serious thoracic or abdominal injury among drivers and front seat passengers involved in motor vehicle crashes, while adjusting for important crash factors. METHODS This was a national population-based cohort of adults involved in motor vehicle crashes from 1995 to 2002 and included in the National Automotive Samp...

Sandwich tube structures bio-mimicking horsetail and human tendons offered significant improvement over traditional single multi-cell tubular energy absorbers. The present research aims to investigate three manufactured hybrid aluminum GFRP sandwich tubes subjected quasi-static low-velocity axial compression. crashworthiness characteristics crushing failure mechanisms of are discussed compared ...

OBJECTIVE The objective of this study was to determine whether occupants of newer vehicles experience a lower risk of crash-related mortality. METHODS The occurrence of death was studied in relation to vehicle model year (MY) among front seat vehicular occupants, age ≥ 16 captured in the National Automotive Sampling System Crashworthiness Data System (NASS-CDS) between 2000 and 2008. The asso...

As shown in article number 2200270 by Xin Ren, Yu Jun Qi, and co-workers, adding two curved ribs to the conventional re-entrant (CRE) honeycomb structure leads formation of a modified auxetic (MRE) structure. During quasi-static compression process, plateau stresses occur load–displacement curves Moreover, energy-absorbing performance MRE is substantially improved with occurrence second stress....
