民用飞机由于自身的结构形式,常在客舱地板面板下布置辅助支撑件。支撑件由于减重原因通常采用较轻质的材料来承受地板传来的部分商载。本文将从结构形式、鉴定试验、载荷分析、有限元计算等方面针对某机型地板支撑件进行校核,验证其在该机型上的承载能力。 Civil aircraft due to its own structure, often in the cabin floor panels arranged under the support. Due to weight loss reasons, the supporter usually adopts lighter weight materials to bear part of the commercial load on the floor. In this paper, the structural support, identification test, load analysis, finite element calculation and other aspects of a floor support for checking, to verify its carrying capacity on the model.
