Abstract

Due to the reduction of vehicle development time and cost constraints, increasing volumes of vehicle development work are being transferred from automotive manufacturers to suppliers. In the area of vehicle structure development, one of the major challenges for suppliers is to deliver a good structural solution in a short time with very limited vehicle data. For those crash-relevant components or modules, such as the A- and B-pillar and the door module, considerable inaccuracies can be expected in the results when using partial vehicle data, as opposed to complete data, with the traditional component validation methods. In this work, a new component development method has been developed, and its implementable crash test bench for small vehicles has been virtually realised. This method focuses on the side impact tests at this phase, such as side impact with a mobile deformable barrier and a side pole impact. Reducing the number of required surrounding components and finding proper boundary conditions that can be implemented in the real test bench are the principle objectives of this work. The results of the crash simulations show a good correlation between the component sub-model and the full vehicle (FV) model using this method.

摘要

由于车辆开发时间和成本限制的减少，越来越多的车辆开发工作正在从汽车制造商转移到供应商。在车辆结构开发领域，供应商面临的主要挑战之一是在车辆数据非常有限的情况下，在短时间内提供良好的结构解决方案。对于那些与碰撞相关的组件或模块，例如 A 柱和 B 柱以及车门模块，如果使用部分车辆数据而不是完整数据，使用传统的组件验证方法，结果可能会出现相当大的不准确性。在这项工作中，开发了一种新的组件开发方法，其可实现的小型车辆碰撞试验台已基本实现。该方法侧重于该阶段的侧面碰撞测试，例如带有移动可变形屏障的侧面碰撞和侧杆碰撞。减少所需周围组件的数量并找到可以在真实测试台上实施的适当边界条件是这项工作的主要目标。碰撞模拟的结果表明，使用该方法的组件子模型和整车 (FV) 模型之间具有良好的相关性。
