高空作業車安定度之分析與測試案例

A Case Study of Stability Analysis and Test of Aerial Lifts

本研究之目的在運用機構運動學分析軟體，建立高空作業車的安定度之分析，以提供高空作業車操作的力學分析模擬。另外，配合高空作業車安定度的實車測試，經由測試結果與分析的比對，以驗證模擬分析的有效性。本研究以台電車載型屈臂式高空作業車為對象，在忽略風荷重等動態荷重因素，進行安定度的分析，包括作業平台各種不同的荷重、作業臂伸展位置及車體斜坡角度等狀況。本研究結果在實用上除可提供高空作業車設計之參考，並可提供未來我國修訂標準與檢查基準草擬的基準。

The objective of this study is to conduct a stability analysis of aerial lifts to improve the safety of their operations. By using the dyanamic analysis software (DADS), stability simulations of aerial lifts are performed. Practical stability tests are also conducted. In this study, a truck type aerial lift with articulatory arms, commonly used in Taiwan, is chosen as the testing model. Dynamic loads, namely wind loads and the loads by motion due to slow movement, are neglected. In stability analyses, several factors such as various loads, unfavorable configurations and different incline surfaces are taken into consideration. Experimental results are utilized to verify the reliability of simulation analyses. This study provides the necessary technical information for the design of aerial lifts, and also help establishing the safety inspection criteria and safety standard revisions in the future.
