Simulating the acoustic field excited by pulse sound sources holds significant practical value in computational ocean acoustics. Two primary methods exist for modeling underwater propagation time domain: Fourier synthesis technique based on frequency decomposition and time-domain model (TD-UAPM). TD-UAPMs solve wave equation domain without requiring decomposition, providing a more intuitive explanation of physical process energy over time. However, time-stepping numerical can accumulate...
Considering the characteristics of multilayered ultra-thin sheet stainless steel, by chosen proper equipments and stored energy welding technology, optimizing parameters are got from condenser discharge spot experiments. The in capacitor group is controlled required during current size dynamic resistance welding. So those control ways can better solve hard problem choosing parameter. joint strength steel ensured reasonable quality assessment methods. processed spot-welded joints good appearance.
For the enormous potential of beam pumping unit’s energy saving, frequency energy-saving control system smart unit with function self-learning has been developed on basis advanced technology and methods both in domestic abroad. The application converter not only solved impact problem at startup, but also improved power factor significantly. solution to shortage oil wells, is sample parameters Motor continuously under conditions relatively original normal working. working liquid level as...
Considering the characteristic of welding process for all-aluminum radiator and meeting needs Chinese production site, low-cost automatic equipment aluminum head has been designed, this paper focuses on its electrical controls. The microkernel main control board is C8051F020. Based subsystems entire piece established, which include LCD，automatic welding, manual operation , parameters setting ,etc. Through trial runs machine, it indicates that design controls rational, full-featured, works...
There has been very little calculation of the composition underwater wet welding plasma. The article collects and analyzes arc spectral information by setting up an experiment platform. Based on results diagnosis study bubble composition, particles considered in were determined. On this basis, Analysis equilibrium equation plasma, law mass action, five basic are selected, other represented these particles, substituted into conservation equations, number density each particle is calculated...
