Experimental study on erosion resistance evaluation of single-layer metal mesh screen

The erosion mass loss of the metal mesh during various working conditions was determined by the weight loss method and the erosion mathematical prediction scheme, in order to determine the erosion life and erosion failure times of the mesh mesh, based on the rotating erosion experiments under various working conditions. When the solid mass fraction and erosion Angle is 15°–45°, the erosion rate is proportional to the solid mass fraction and Angle of erosion.

Optically transparent and very thin structure against electromagnetic pulse (EMP) using metal mesh and saltwater for shielding windows

Abstract An electromagnetic pulse with high energy can destroy electronic equipment within seconds of a wide variety of thousands of kilometers. Typically, a metal plate embedded within a thick concrete wall is used against an EMP, but it is not suitable for an EMP shielding window because it requires not only high shielding tenacity but also optical clarity. For the EMP shielding window application, we recommend a very thin and optically transparent structure with high SE. The glass's proposed structure is made up of a saltwater layer sandwiched between two glass substrates and two metal mesh layers on the outside of the glass, with a total thickness of less than 1. 5 cm. Moreover, the OT of the building can be substantially enhanced with just one metal mesh film layer, while the SE is still high to satisfy the required SE for home applicants.

Simulation of the Dynamic Response to Sinusoidal Excitation of the Elastic Porous Metal Mesh Damper

The elastic porous metal mesh damper has received a lot of attention from researchers as a promising means of vibration isolation for rocket engine turbopumps, turbine engines, and other types of rotordynamic applications. However, the engineering of a metal mesh damper hinges heavily on the trial-and-error procedure for tuning manufacturing parameters, excluding it from widespread use in rotor-bearing applications. Quantistatic and dynamic mechanical experiments were carried out to help determine the primary factor that influences MMD's damping results and to show how MMDs' dynamic behavior changes with the manufacturing parameters. The mixed damping model demonstrates excellent predictive performance under various excitation conditions by incorporating mesh density and motion amplitude into the expression of variables such as stiffness coefficient, damping coefficient, and damping component factor.
