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。
Conventional helicopter landing gear calculations include downtime calculation and reduction mass calculation, static performance calculation and landing gear landing gear calculation. To complete these calculations requires a lot of data and landing gear. In the development process, in order to obtain the optimal design, the parameters of the landing gear need to be constantly adjusted, and the calculation results are repeatedly analyzed and compared with a large amount of calculation, and the data processing is complicated and time-consuming. Describe in detail how to use Excel and Matlab to integrate the conventional calculation of landing gear. To complete a routine calculation of a helicopter landing gear, an M code of more than 2000 lines was prepared using this integration method. Running on a Hewlett-Packard Z800 computer platform, it takes more than 400 seconds to complete all the relevant calculations. Input and output data stored in the same Excel file, file parameters and calculation results can be used directly for inspection, proofreading, analysis, but also re-editing.
