基于Matlab的某机场升降摆渡平台举升油缸铰点位置设计

Pivot Location Design of Lifting Cylinder for Airport Lifting Ferry Platform Based on Matlab

为减小摆渡平台举升作业过程中液压缸的最大推力,建立了举升作业的数学模型,通过虚位移原理对液压缸的推力进行解析分析,利用Matlab定量研究举升油缸位置参数对油缸最大推力的影响。根据工程要求与结构参数,通过仿真分析确定以油缸推力最小为设计目标的铰点位置参数。结果表明,油缸的铰点位置与油缸推力存在非线性对应关系,在满足空间布置要求的基础上,铰点布置方案应以油缸受力最小为设计目标。

The mathematical model of lifting operation is established to reduce the maximum thrust of ferry platform. With this model, the paper studies the influence of lifting cylinder location parameter to maximum thrust with Matlab after analy- zing the thrust with virtual displacement principle. The pivot location parameter with minimum thrust is obtained through simulation analysis according to engineering requirement and structure parameters. The result shows that the pivot location has nonlinear corresponding relation with thrust, and the pivot layout should take cylinder＇ s minimum trust as the design goal on the basis of meeting the requirement of space layout.
