Model experiment and damping identification for aeroelastic stability of helicopter rotor with elastomeric lag damper 带粘弹减摆器旋翼系统气弹稳定性试验与阻尼识别
Numerical simulations demonstrate that the multi body analytical model can analyze the aeroelastic stability of the tiltrotor aircraft in the helicopter mode 数值计算表明:建立的多体动力学模型能够快速分析直升机模式下倾转旋翼机复杂的旋翼机翼气弹耦合动力学特性。
By numerical simulation , the servo system in this paper greatly reduces the aeroelastic stability . the structural flitter added to the system can reduce the coupling effect of servo system and structure mode and increase the flutter velocity 通过数值模拟发现,伺服系统会降低原有气动弹性系统的稳定性,结构陷波器的引入可以减弱伺服系统和结构模态的耦合。
