直升机振动问题受到广泛的关注,振动问题关系到机组人员的舒适性及人机工效性。部件的振动问题往往与该部件的动力学特性具有较大的关联。本文以某直升机中央操纵台振动问题为例,通过仿真分析、试验验证等手段,对问题的机理进行分析,对安装结构进行动力学设计,提出改进措施,并通过试验、试飞验证,表明了改进措施的有效性。
The issue of helicopter vibration has received widespread attention. The issue of vibration has a bearing on the crew’s comfort and ergonomics. The vibration problems of the components often have a greater correlation with the dynamic characteristics of the components. Taking the vibration problem of a central control console of a helicopter as an example, this paper analyzes the mechanism of the problem by means of simulation analysis, experimental verification and so on. The dynamic design of the installation structure is proposed, and the improvement measures are put forward. The test and flight test demonstrate that the improvement The effectiveness of the measure.
