某飞行器通用包装箱结构设计研究

Structural Design of General Packaging Box for Vehicle

目的针对每种飞行器都需要设计专用的包装箱现状,设计一种新型通用化的包装箱,满足运输与起吊要求,可适应多种飞行器的使用。方法根据设计要求进行了包装箱的结构设计,利用有限元分析方法与工程算法对运输工况、起吊工况进行分析,并进行可靠性、安全性、维修性和保障性分析。结果得到了在运输与起吊最大质量产品工况下,包装箱钢骨架的最大应力分别为166 MPa和215 MPa,小于材料的屈服强度,满足强度要求,且具备较高的可靠性、安全性、维修性和保障性。结论包装箱结构设计满足设计要求,可用于多种尺寸的飞行器运输,降低了设计成本。

In view of the current situation that each type of vehicle requires a dedicated packaging box,the work aims to design a new type of general packaging box that can meet the transportation and lifting requirements and adapt to a variety of vehicles.The structure of the packaging box was designed according to the design requirements.The transportation and lifting conditions were analyzed with finite element analysis methods and engineering algorithms and the reliability,safety,maintainability and supportability were analyzed.It was obtained that the maximum stress of the steel skeleton of packaging box was 166 MPa and 215 MPa under the condition of transporting and lifting the product of the maximum mass,which was smaller than the yield strength of the material,meeting the strength requirements and ensuring high reliability,safety,maintainability,and supportability.This structural design of packaging box meets the design requirements and the packaging box can be used for transportation of vehicles of different sizes with lower design costs.
