Blade Flutter

Blade is one of the main parts of aircraft engine. Its dynamic characteristics will produce important influence on the work efficiency and the operation reliability of the turbine engine. The paper used the theory of finite element to do modal simulation analysis on the dynamic characteristic of blade flutter, aiming at the phenomenon of serious blade vibration in the process of turbine engine running. Firstly, the paper generated a three-dimensional model by using the software UG. Then the three-dimensional model was leaded into the finite element analysis software ANSYS. Simulation analysis of the model was carried out by using the Workbench module of ANSYS software. Finally, we got the former six order natural frequencies and vibration modes of the blade. In addition, we got the blade's vibration characteristics. The results of the simulation could provide numerical basis for the blades optimization design and vibration safety inspection.

And Function

The structure of nonwovens gives special functions, and the establishment of the structure model has important reference significance for the realization of functions. In this work, the two-dimensional configuration of polyester fibers in a spunlaced nonwoven fabric was extracted, and the configurational feature points of 2500 fibers were obtained. Combined with the generative adversarial nets algorithm, the generation model of the two-dimensional configuration of fibers was proposed after learning the configuration feature of 2500 fibers. Based on the assumption that the fibers are randomly distributed in the nonwoven fabric, we established a three-dimensional model of the spunlaced nonwoven fabric on the fiber scale using ABAQUS software. In addition, the water diffusion experiment and simulation were carried out to visualize the diffusion process of a water droplet in the nonwoven fabric, verifying the accuracy of the model. This method provides a novel idea for the modeling of textile structure on the fiber scale, which can be regarded as a model basis for the subsequent simulation analysis and function research.

As the key component of mechanical picking device of marigold flower, the structure, size, strength and motion of comb are closely related to the reliability and the rate of picking. In this paper, a mechanical comb for marigold based on bionic finger is designed, and the parameters of structure, row, spacing and outside diameter are designed respectively. Then, the three-dimensional model is established with ANSYS/LS-dyna platform, and the design strength of the comb-type picking mechanism is checked. The results show that the maximum deformation of the comb with 2.3802mm occurs near the top of the tooth during the picking process, which is small and meets the design strength requirements. Finally, the picking process of the comb-type picking mechanism is simulated and the result shows that when the operating speed v is set to 3.0km/h and w is set to 30r/min, the picking effect is good. The above research provides a theoretical reference for the mechanical picking of marigold.
