In this paper polymer structural foams are being investigated in body structure applications. There are two major polymer foam technologies for structural applications: the well-known epoxy based inse....
This paper describes the methodology and analyses used to engineer and evaluate a 37% mass-reduced body structure relative to a baseline, steel body-in-white (BIW). This paper is based on two publishe....
In an attempt to assist pressure sensor algorithm and calibration development using computer simulations, an Arbitrary Lagrangian Eulerian (ALE) approach was adopted in this study to predict the respo....
Automakers are putting ever more emphasis on their environmental and energy efficiency efforts through improving the fuel consumption of vehicles. One way of saving energy is to reduce the total weigh....
The Hybrid III 50th male dummy[1] is used globally in vehicle safety for measuring the damage index of dummy components. This paper focuses on the dummy's ankle structures which have a great effect on....
Despite increasingly stringent crash requirements, the body structures of future mainstream production cars need to get lighter. Carbon fiber reinforced polymer (CFRP) composites with a density 1/5th ....
The whiplash disorders are associated with huge costs for society. The BioRID (Biofidelic Rear Impact Dummy) dummy and the test procedure are developed to ensure the seat systems optimized to reduce t....
This investigation introduces a methodology to design dynamically crushed thin-walled tubular structures for crashworthiness applications. Due to their low cost, high-energy absorption efficiency, and....
With a goal to help develop pressure sensor calibration and deployment algorithms using computer simulations, an Arbitrary Lagrangian Eulerian (ALE) approach was adopted in this research to predict th....
In response to more stringent greenhouse gas and fuel economy standards and increasing consumer demand for fuel efficient vehicles, automobile manufacturers have identified vehicle mass reduction as a....
It is well known that an unplanned component mass increase during vehicle design creates a ripple effect of changes throughout the vehicle subsystems, which require resizing for the additional mass. T....
Thermoplastic polyester elastomer (TPEE) possesses the properties of both rubber and engineering plastic. The most important feature of this material lies in its ability to combine the superior repuls....
To investigate the effect of aeration on fluid-elastomer compatibility, 4 types of elastomers were aged in three gear lubes. The four types of elastomers include a production fluorinated rubber (FKM) ....
The front rail, as one main energy absorption component of vehicle front structures, should present steady progressive collapse along its axis and avoid bending collapse during the front oblique impac....
This paper investigates the crashworthiness of structural composite components in frontal and side crash tests. In addition, the safety benefits of composites applications in future lighter vehicles a....
New regulations are challenging the automotive industry to find technology solutions to meet new emissions and fuel economy standards. Engine downsizing and power boosting technologies, hybrid and ele....
Carbon nanomaterials such as vertically aligned carbon nanotubes arrays are emerging new materials that have demonstrated superior mechanical, thermal, and electrical properties. The carbon nanomateri....
In this paper, a microstructure-based three-dimensional (3D) finite element modeling method is adopted to investigate the effects of porosity in thin-walled high pressure die-cast (HPDC) magnesium all....
