The LVD-AT10 Electrodynamic Vibration Test System (ISO 17025 CNAS Certified) offers a comprehensive solution for mechanical environmental testing with a selectable force range from 1 kN to 60 kN. This system is engineered for precision testing applications across aviation, aerospace, maritime, rail transit, and new energy sectors, featuring a wide frequency range, operational efficiency, and simplified maintenance protocols.
Vibration represents oscillatory motion about an equilibrium position, characterized by time-dependent physical parameters including displacement, velocity, and acceleration. Classification methodologies include causal analysis (free vibration, forced vibration, self-excited vibration), waveform characteristics (sinusoidal vibration, random vibration), and degrees of freedom (single-degree-of-freedom vibration, multi-degree-of-freedom vibration).
The Electrodynamic Vibration Test System operates on electromagnetic induction principles, converting electrical energy to mechanical energy through transducer technology. The fundamental operating principle derives from Ampere’s law: a current-carrying conductor within a magnetic field experiences electromagnetic force proportional to current magnitude, effective conductor length within the magnetic field, and magnetic flux density. Force directionality follows the left-hand rule. When subjected to resistance within a constant magnetic field, the moving coil experiences variable forces that generate controlled vibration.
The system’s moving coil winding operates within a high magnetic flux density gap. Vibration signals originate from signal generators or vibration controllers, undergo amplification through power amplifiers, and transmit to the moving coil winding to produce specified vibration profiles…
