摘要
本文介绍了旋翼/机身组合模型试验台“地面共振”分析方法,给出了装上不同旋翼模型时的“地面共振”分析结果。为了满足旋翼/机身组合模型试验台“地面共振”稳定性要求,根据试验台不同的工作环境,应对试验台进行相应的结构更改,以改变试验台的动特性,使之与旋翼模型相匹配。本文详细介绍了采用这一措施成功地解决×旋翼模型在试验台上运转时的动力稳定性问题。
In this paper, the analytical method about the
'ground resonance' is introduced. It is applicable
to test stand of the rotor/fuselage combined model
The conclusion is also presented in this paper when
different rotor models are mounted. In order to
meet the stability requirements about the 'ground
resonance' of the test stand, the change about the
structure in the stage should be made according to
the different working circumstances. Thus, we
can change the dynamic charastics of the testing
stage, so that it can match the rotor model By
this method, we can successfully solve the dynamic
stability problem × rotor model is riming on the
testing stage, and it is discussed in the paper.
