Abstract: A magneticmechanical oscillation device is constructed and its relevant physical parameters affecting the vibration of the spring plate and the dynamic process of vibration are systematically studied. The experiments find that the stiffness coefficient, natural frequency, magnetic force, and magnet mass are the key factors affecting the vibration. The existing simple harmonic vibration equation is revised by incorporating resistance, magnetic force, and other interaction forces, transforming it into the combined vibration equation for the spring plate. Numerical solutions are performed on the combined vibration equation and the results are consistent with the experimental results.

Key words: magneticmechanical oscillator, vibration equation, damped vibration
