Vehicle Data Sources for the Accident Reconstructionist

Body in White: The assembly stage of a car body in which the body panels are present and attached by welds and/or structural adhesive before painting, but not the nonmetallic, bolted, screwed, or clipped-on parts. It does not include moving parts (doors, hoods, and deck lids) or fenders, the motor, chassis subassemblies, or trim (glass, seats, upholstery, electronics, and so on). It may be thought of as the structure of the vehicle body.
Multi-material design of a vehicle body considering crashworthiness safety and social effects

The vehicle body, or the body in white (BIW), accounts for approximately one-quarter of the overall mass of the vehicle and exerts a predominated function in resisting the crash loads in different crash situations [1]. In this study, 15 major components of the vehicle body were selected as analytical factors and their relevant sectional codes in the numerical models are depicted in Table 1. For an intuitional observation, the detailed depiction is shown in Figure 2. It is noted that the numerical model was calculated using the commercial codes in LS-DYNA [27], and some typical components with the mesh works are exhibited in Figure 3.
Optimizing the beam-like structure of a vehicle body using the grey–fuzzy–Taguchi method

The static–dynamic performance of the body-in-white (BIW) plays a key role in improving vehicle safety, noise, vibration and harshness, and the handling quality of a car (Malen 2011; Rashid et al.2014; Kiani, Shiozaki, and Motoyama 2015). Several basic problems associated with crashworthiness, resonance, fatigue and reliability can be avoided by improving the static–dynamic characteristic of the BIW. The BIW primarily consists of thin-walled beams and sheet metal structures. Thus, the thickness of the components and shape of the cross-section of the thin-walled beam significantly influence the structural performance.
An investigation of the crashworthiness performance and optimization of tetra-chiral and reentrant crash boxes

The vehicles are designed to keep the mass of the body-in-white to a minimum while satisfying the safety requirements. In this context, mass is an important parameter when designing a crash box. SEA is an important criterion used to measure the EA capacity per unit mass of the structure, which is obtained by dividing the total absorbed energy, as shown in Eq. (2) by the pre-collision mass (m) of the structure.
