Crash simulation of entire vehicle structures is of great importance in the development process of vehicle construction. The load-bearing behavior of the entire vehicle structure is considerably influenced by its joints, whereby the joint areas in the crash simulation must be represented by simplified models. In order to validate the simplified models, sample component tests, which allow the mapping of application-oriented load conditions, are absolutely necessary. However, the current testing facility for performing validation tests under crash loading on component-like specimen geometries regularly reaches its physical limits. Furthermore, the decisive influence of temperature and humidity cannot be taken into account, especially in the case of adhesive joints. The lack of suitable high-speed cameras makes it impossible to evaluate the failure behavior at high test speeds. The large-scale equipment applied for here expands the existing research possibilities and enables the Research Department to carry out corresponding investigations experimentally and consistently continues the previous and future focus of the Research Department third-party funding research.

整车结构的碰撞仿真在汽车结构的发展过程中具有重要意义。整车结构的承载性能受其接头的影响很大，因此碰撞模拟中的接头区域必须用简化的模型来表示。为了验证简化的模型，允许映射面向应用程序的负载条件的示例组件测试是绝对必要的。然而，目前用于在碰撞载荷下对类似部件的试件几何形状执行验证测试的测试设施经常达到其物理极限。此外，不能考虑温度和湿度的决定性影响，特别是在胶接的情况下。由于缺乏合适的高速摄像机，因此无法评估高速测试时的故障行为。这里申请的大型设备扩大了现有研究的可能性，使研究部能够在实验上进行相应的调查，并始终如一地延续了研究部第三方资助研究过去和未来的重点。
