Abstract


Rotor chamber normally used for storing or leaks into the liquid, constitutes a fluid rotor system. Such as aero-engine rotor shaft section and the drum cavity, improper or malfunction due to design, fluid failure occurs. As long as the lumen of a small amount of fluid, it will significantly affect the vibration characteristics of the rotor system. In this paper, using the finite element method first rotor system dynamics were analyzed to establish a rigid rotor system hybrid virtual prototype model, and verified by experiments to correct the model. On this basis, the establishment of the oil has accumulated a virtual prototype model for the dynamic simulation, qualitative analysis of the product oil on the stability of the rotor system and plot the movement of oil, and experimental verification. Achieved the following results: (a) for an aircraft engine rotor system was simplified modeling and using ANSYS and MATLAB programming language, solving the simplified rotor system first four natural frequencies and mode shapes, as established below, the virtual prototype rotor system model analysis to prepare. (2) the use of simplified rotor system SOLIDWORKS build three-dimensional solid models imported into the multi-body dynamics software MSC.ADAMS and flexible shaft into the body, establish simplified rotor system virtual prototype model for dynamic simulation. Through experimental verification, the virtual prototype model for an effective amendment to make the virtual prototype model of the rotor system has a good simulation accuracy. (3) the product of the rotor system, the oil pan, filling into a small amount of oil, the oil formed a plot rotor system. Through experimental observation of the rotor system with integrated oil at low speed and a first critical speed close to the oil accumulated in the oil pan plot the distribution of the body cavity. (4) According to the experimentally observed distribution of the product oil, the oil reservoir rotor system can be simplified, to ensure the quality and density of the fluid under the same circumstances, let the fluid flow constant. Establishment of a rotor system with integrated oil virtual prototype model. Had accumulated oil Rotor System Dynamics simulation, the simulation results. And test bench results compared qualitatively analyzed the rotor chamber volume of oil on the rotor system effects and plot the movement of oil and be verified by experiments. Based on a simplified aero-engine rotor system model for the study of the rotor system integrated oil fault simulation studies to analyze the accumulated oil on the stability of the rotor system and plot the movement of oil. Verified by experiments proved that using multi-body dynamics MSC.ADAMS software fault on the rotor system oil reservoir simulation analysis of the feasibility of aero engine rotor system integrated oil phenomenon analysis provides a theoretical reference, has a positive practical significance and economic value .
