Synchronization of a Dual-Mass Vibrating System with Two Exciters

الملخص EN

From the perspective of theoretical derivation, numerical simulation, and engineering application, the vibratory synchronization characteristics of a dual-mass vibrating system driven by two exciters, were studied.

The differential motion equations of the total system were calculated using Lagrange’s equations, and the responses of the vibrating system in the steady state were derived by Laplace transform.

The synchronization criterion between two exciters was deduced by using the averaging method.

Based on the Hamilton principle, the stability criterion of the vibrating system in synchronous states is given.

According to the theoretical results, the coupling characteristics between two exciters such as synchronization and stability were analyzed numerically.

Some analyses of the numerical simulation of the system were carried out, which fully support the theoretical results.

The rotational speed of two exciters, their phase difference, responses, and difference of responses of two rigid bodies were studied quantitatively in the subresonant state and super-resonant state of the system.

This paper presents a practical example of vibratory synchronization of a dual-mass system driven by two exciters in engineering.
