| 摘 要： | 本文对直升机桨叶在折叠和打开过程中的受力进行了分析,推导出了桨叶在桨叶折叠和打开过程中所需要提供的力矩的一般表达式,并在此基础上给出了活塞杆所需提供的拉力或推力的计算公式。最后,考虑到最终计算的复杂性以及后续研究,采集几个通用的计算参数后用VB编写了一个计算软件,适用于一般的桨叶折叠受力计算。

| Abstract: | This paper analyzes the force bearing of a blade during folding or opening,and obtains the formula of torque needed during folding or opening.Basing on these formulas,the computing formula of the pulling or thrusting force the piston rod born during folding or opening is given out.In the last,considering the complexity of computing with these formulas,a software written in VB programming language is offered and it is applicable to general blade folding. |
