Abstract: The thermoelastic coupling vibration characteristics of the axially moving beam with frictional contact are investigated. The piecewise differential equation of motion for the axially moving beam ...

Abstract: Many processes are characterized by their oscillating or cyclic time behavior. This holds for rotating machines or alternating currents. The resulting signals are then periodic signals or contain periodic parts. It can be ...

Abstract: The major techniques for measuring jet noise have significant drawbacks, especially when including engine installation effects such as jet–flap interaction noise. Numerical methods including low order correlations and ...

Abstract: Central continuous heating is widely used in China. Due to the large heating area, the indoor temperatures of the buildings with the same heat source are quite different, which affects comfort and wastes energy. This paper ...

Abstract: Cable-network structures are an important part of mesh reflector antennas. The performance of antennas depends greatly on the surface accuracy and tension distribution. However, there are periodic temperature changes in ...
