直升机起落架的集成计算

直升机起落架常规计算包括停机状态计算及减缩质量计算、静态性能计算及主、尾起落架的着陆性能计算.要完成这些计算需要整机及起落架的诸多数据.在研制过程中,为了获得最优的设计,需要对起落架的各参数进行不断调整,对计算结果进行反复分析和比较,计算量较大,数据处理较为繁复耗时.详细阐述如何采用Excel和Matlab对起落架的常规计算进行集成.为完成一种直升机起落架的常规计算,采用该集成方法,编制了2000余行的M代码.在惠普Z800计算机平台下运行,耗时400余秒即可完成所有相关计算.输入输出的数据存储在同一Excel文件,文件中各项参数和计算结果数据可直接用于查阅、校对、分析,也可再编辑.

The Integrated Calculation of a Landing Gear in a Helicopter

The routine calculation of a landing gear in a helicopter includes the calculation of parking,the calculation of equivalent mass,the static performance calculation,the performance calculation of main & tail landing gear.To finish all the calculation,many data of the plane and landing gear is needed.During the research,to achieve the optimal design,many adjustment of the parameter occurs.The analyses and contrast of result has been done again and again.The quantity of the calculation is large,and the data processing costs lots of time.The paper described how to integrate the calculation of the routine landing gear by Excel and Matlab.To finish the routine calculation,programmed 2000 rows M code using the integrated method.Running the code on the HP Z800 computer plat costs about 400 seconds.The input and output data saved in a Excel file,and all kinds of data are available for reference,analysis and contrast,and can also be edited again.
