TRC Challenge - design documents

This dataset contains all specifications to manufacture and assemble a new benchmark structure for the experimental analysis of nonlinear vibrations. The setup includes a support structure, a thin panel and two blades. The blades are used to clamp the panel at the left and right side to the support. Due to a small inclination of the relevant surfaces of the support, the panel is slightly curved in the assembled state. This curvature and the clamped-clamped boundary situation give raise to a pronounced softening-hardening behavior (considering the dependency of the panels natural frequency on the vibration level). Moreover, a friction nonlinearity is expected due to the bolted joints used to clamp the panel. Here we provide all technical drawings, 3D CAD files in *-stp.format, material specifications and a detailed documentation needed to manufacture and assemble the benchmark in a reproducible manner. It is recommended to read 'DesignDocumentation-revD.pdf ' first to get an overview.

本数据集囊括了用于制造和组装用于非线性振动实验分析的全新基准结构的全部规范。该装置包括支撑结构、薄板和两片叶片。叶片用于将薄板夹紧在支撑结构的左侧和右侧。鉴于支撑相关表面的微小倾斜，组装状态下的薄板呈现轻微的弯曲。这种弯曲状态以及夹紧-夹紧的边界条件引发了显著的软化-硬化行为（考虑薄板固有频率随振动水平的变化依赖性）。此外，由于使用了螺栓连接来夹紧薄板，预期将出现摩擦非线性。在此，我们提供了所有技术图纸、*-stp格式的3D CAD文件、材料规范以及制造和组装基准结构所需的详细文档，以确保可重复性。建议首先阅读'DesignDocumentation-revD.pdf'以获取概览。
