Abstract

This article reviews approaches to mathematical modeling of a vehicle crash. The growing focus on vehicle and occupant safety in car crashes has triggered the need to study vehicle crashworthiness in the initial stages of vehicle development. The major motivation for this work is to support vehicle crashworthiness design during the product development process.The article is divided into two parts; the first one overviews existing mathematical models used to solve engineering problems. The second part describes modeling strategies applied for replicating non-linear vehicle crash event and occupant kinematics in an occupant protection loadcase. We also highlight alternative modeling strategies using hybrid modeling techniques aimed at the improvement of the vehicle development process.

摘要

本文回顾了车辆碰撞数学建模的方法。在车祸中对车辆和乘员安全的日益关注引发了在车辆开发的初始阶段研究车辆耐撞性的必要性。这项工作的主要动机是在产品开发过程中支持车辆的耐撞性设计。文章分为两部分；第一个概述了用于解决工程问题的现有数学模型。第二部分描述了用于在乘员保护工况中复制非线性车辆碰撞事件和乘员运动学的建模策略。我们还强调了使用旨在改进车辆开发过程的混合建模技术的替代建模策略。
