Free Vibration Characteristics on a Split Torque Transmission
نویسنده
چکیده
The free vibration characteristics of a dual split torque transmission are studied in this work. A transversetorsional coupling dynamic model is developed using lumped parameter method. The natural frequencies and mode shapes are calculated by solving the eigenvalue problem of the differential equations of motion. The vibration modes of the system are classified into translational mode and rotational mode, and the characteristics of the two modes are described in details. The modal strain energy and kinetic energy are introduced to study the impact of mesh stiffness, component masses and moments of inertia. The influence of the concerned parameter on a certain mode can be effectively determined by inspection of the modal energy distribution. The effect of the torsional stiffness of the shaft connecting two stages is also studied. The results presented in this work can provide references for the design of dynamic performance of the split torque transmission.
