摘要
对直升机以一定速度坠落时产生的冲击振动等动力学响应进行了仿真研究,基于能量原理和振动理论,理论推导得出了该型直升机主起落架缓冲器纵向振动微分方程计算公式,并在动力学仿真软件ADAMS基础上,进行了数字仿真机算。仿真结果表明,理论计算值和仿真算例吻合较好,所得结论对于起落架缓冲器设计具有工程意义。
The dynamic response of a helicopter to the impact of the surface of the earth with damp is analyzed using the energy principle and vibration theory. A formula concerning the vibration differential equation of the landing gear is obtained from theoretical analysis. Based on ADAMS mechanical simulation software, a gravity environment was established by computer and some simulation study had been carried out about the landing gear damper. The academic result has been verified using a numerical example, and the simulation result is in very good agreement with the calculated result. The conclusions drawn in this paper could be used for engineer.
