摘要

传动系统是直升机关键核心部件,对其开展虚拟仿真分析与动力学特性研究,在其全寿命周期各个阶段均具重要作用。通过CATIA软件建立直升机传动系统三维实体模型,进行了典型工况下的载荷计算,在ADAMS环境下建立整个传动系统的虚拟样机模型。对模型进行了运动仿真分析,提取并分析了主要啮合齿轮对角速度、啮合力的时频域曲线,仿真结果与理论计算值相吻合。为直升机传动系统结构优化设计及疲劳预测寿命分析等提供模型和理论基础。

Abstract

The transmission system is the key components of the helicopter,the study and analysis of the dynamics characteristic and virtual simulation have an important function for the whole life cycle in every stage.The 3D model of the helicopter transmission system is established by CATIA software,the load under the typical working condition is calculated,and the virtual prototype model is built under ADAMS software. The kinematic simulation analysis of the model is carried out,the rotate velocity and the time and frequency domain curves of meshing force of the main meshing gear are extracted and analyzed,the simulation results are consistent with theoretical calculation results. The research work can provides the model and theoretical basis for structure optimize design and analysis of fatigue and forecasting life of the helicopter transmission system.
