摘要:: 设计机场集装箱/板升降平台车的桥平台结构,对桥平台的关键受力部件上台面和剪叉臂进行静力学分析,并校核其强度.对桥平台处于最高位置时进行模态分析,提取运算结果.桥平台前五阶固有频率集中在3～17 Hz的低频阶段,各阶振型主要表现为上台面和剪叉臂摆动、扭曲.桥平台的静力学及模态分析结果为桥平台的设计提供了理论依据.

Abstract:: Design the bridge platform structure of the airport container/board lifting platform vehicle, conduct static analysis on the key stress-bearing parts of the bridge platform, the upper table and the scissor arm, and check their strength. Perform modal analysis when the bridge platform is at the highest position, Extract the calculation results. The first five natural frequencies of the bridge platform are concentrated in the low frequency stage of 3-17 Hz, and the mode shapes of each order are mainly manifested as the swing and twist of the upper platform and the scissor arm. The static and modal analysis results of the bridge platform are: The design of the platform provides a theoretical basis.
