液壓脈動(dòng)引起液壓管路和壁板振動(dòng)的振動(dòng)響應(yīng)分析
[Abstract]:As the main power source of modern aircraft internal mechanism, hydraulic system plays an important role. The hydraulic pipe is often damaged by vibration, which causes the damage of the pipe structure and the parts connected with it, the light one causes the rupture and leakage, and the heavy one causes the mechanical destruction and death. According to statistics, the proportion of fatigue failure caused by vibration and shock iso-dynamic load is more than 40%. The dynamic failure of fluid-solid coupling components such as pipelines and pipe connectors has become the main cause of aircraft failure, so it is the most important thing to solve the vibration problem of hydraulic pipes in the design of aircraft. In this paper, finite element simulation software-ANSYS / Workbench is used to study the vibration characteristics of pipe wall structure. Firstly, the fluid-solid coupling theory is introduced, and the application of finite element simulation software ANSYS/Workbench in modal analysis and transient analysis is also introduced. Secondly, this paper uses CATIA to model the pipe wall structure, and explains the model data transfer between CATIA and ANSYS, and carries on the finite element preprocessing to the imported model in ANSYS. Then, the modal analysis of the whole structure is carried out by using the MODAL module of ANSYS, and the optimization of the structure is put forward. The improved model is simulated by finite element method, and the rationality of the improvement measures is analyzed. Finally, the Transient structure module of ANSYS is connected with CFX to simulate the vibration response of pipe wall structure at any point under the impact of hydraulic sinusoidal pulse in pipeline.
