Variable test equipment for testing joined component-like samples under crash load and climatic influence

整车结构碰撞仿真在汽车制造的发展过程中具有重要的意义。整个车辆结构的承载性能受其关节的影响很大，因此碰撞仿真中的关节区域必须用简化模型来表示。为了验证简化的模型，样本组件测试是绝对必要的，它允许映射面向应用程序的负载条件。然而，目前用于在类似组件的试样几何形状的碰撞载荷下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，特别是在粘接的情况下。由于缺乏合适的高速摄像机，因此无法评估高测试速度下的失效行为。本项目采用的大型设备拓展了现有的研究可能性，使研究部能够进行相应的实验研究，并始终如一地延续研究部以往和未来第三方资助研究的重点。

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.
