Forced Longitudinal Oscillations of a Rod with a Mass at the Endrated mass is attached to the right end. The source of the oscillations is the harmonic force acting along the axis. The mathematical model consists of a hyperbolic partial differential equation and boundary conditions. The D‘Alembert‘s principle is used. Forced oscillations are undamped and harmoniCLOWN 发表于 2025-3-30 22:12:05

Modeling of the Adjustable DC Voltage Source for Industrial Greenhouse Lighting Systemsmparison with the standard AC power supply mode, the proposed DC power supply approach with a cyclic change in the polarity of the supply voltage allows to increase the light output by up to 20%. The purpose of the article is to develop a mathematical model of a regulated DC source necessary for con防御 发表于 2025-3-31 05:07:19

At the final stage of determining the frequencies of free oscillations, a numerical-graphical method is used, implemented in the environment of the Matlab computing complex. A concrete example of the solution is given. Conclusions are drawn.
