摘要

本文旨在探討振動試驗機之輔助平台設計流程，舉一實際平台範例說明設計方法及其驗證流程，並探討新平台設計之概念構想。透過實驗與理論模態分析驗證有限元素模型為等效之分析模型。將實驗及理論分析之頻率響應函數代入響應評估程式，獲得實際及預測之響應，以比較驗證理論分析所預測平坦度之正確性。藉此，設計新型式平台並套入此平坦度預測程式，以獲得更優的平台設計。本文建立平台之設計分析與響應預測方法，可做為未來新型式平台之設計分析之依據。

This paper discusses the design process for the development of auxiliary table of vibration testing machine. The design process is first laid out, and a typical auxiliary table is studied to show the design evaluation. There are three stages in terms of design analysis. First, the table in free boundary is performed by both finite element analysis and experimental modal analysis to validate the analytical finite element model. Second, the fixed boundary conditions corresponding to the real mounting is considered and validated as well. Third, the flatness index to evaluate the table performance is adopted and shown to justify the table design. Finally, the design criteria for a new design of the auxiliary table are presented. This work establishes the design methodology of auxiliary table that can be suitable and coped with the requirement of vibration testing machine.
