Baogang Cold Plate Leveler Main Drive System Torsional Vibration And Strength Analysis Model

Straightening in the cold, hot-rolled, plate rolling process, etc. has become a necessary process, straightening machine is to achieve optimum flatness of steel plates one of the key equipment. Production process in the actual straightening, ensuring the quality of steel. Baosteel Heavy Plate Mill 9 5m heavy plate cold roll straightening machine, SMS from Germany in 2003 the company introduced one of the most modern equipment in 2005 to start debugging, trial production. In equipment commissioning, pre-production stage there have been some problems, especially straightening machine main drive shaft universal joint overload damage, the problem is the same urgent problem. First, the physical model is simplified as no deformation of the rigid rotor and the inertia of the elastic element without the establishment of the main drive system torsional vibration of the mechanical model, by solving the dynamic equation eigenvalue problem, access to the system's natural frequency and vibration mode and its moment of inertia. Found that torsional vibration of rolling mill main drive and the main vibration mode natural frequency distribution is reasonable, the basic design criteria to meet the optimum power. Secondly, based on the established model of torsional vibration, the use of Matlab software to study the dynamic response of the system to obtain the torque of each shaft segment amplification factor (TAF).Finally, the use of Ansys software, spline and coupling the three dimensional finite element method. At rated torque, find the maximum stress location to check the strength, after the straightening process parameters for the setting of high-strength sheet metal straightening ability to identify and rational use and maintenance of equipment provide a theoretical basis and make full technical reserves.
