摘要

防止滑橇式直升机地面共振机体需用阻尼分析是一个重要的设计问题。首先开展了直升机在滑橇起落架上的振动特性仿真分析与试验验证研究,从而确定了采用仿真方法计算机体当量质量和当量刚度是可行的。其次采用地面共振平面动力模型进行地面共振分析,提出以满足地面共振稳定性设计要求为约束目标的机体需用阻尼优化设计方法。最后,以某型滑橇直升机为例,研究了机体重量、旋翼减摆器参数变化对机体需用阻尼的影响,结果表明滑橇直升机在大重量、高温情况下机体纵向平动模态需用阻尼最大。

Abstract

Aanlysis of airframe damping required to preven ground resonance of skid helicopter is a important design issue. First,the simulation analysis and test verification study of helicopter vibration characteristics on the skid landing gear were carried out. The simulation methon is used to determine the equivalent mass and equivalent stiffness of skid helicopter airframe. Then use the ground resonance plane dynamic model for ground resonance analysis. Taking satisfying the design requirements of ground resonance stability damping as the constring goal, carrying out the optimization design analysis of the damping required. Finally, taking a certain type of helicopter as an example,the influence of the weight of the airframe and the parametes of the rotor admper on the required damping of the airframe is studied. The results show that the longitudinal translation mode of the skid helicopter needs the maximum damping under the condition weight and high temperature.
