| Title: | SimulateIT - Drive Dynamics Analysis |
| Author(s): | FORMÁNEK, Ivo |
| Text: | This contribution presents applications and abilities of SimulateIT - Drive Dynamics Analysis Program (called briefly as DDA tool). The tool is a new ABB software product for optimization of dynamic performance of electromechanical drives. DDA tool can help a skilled user to answer questions as follows: E.g. “Are we utilizing the drive system or the drive systems optimally? Where can be reasons of excessive vibrations or impacts causing wear and tear or unplanned stoppages? What can bring about mechanical breakdowns of the drive system? How should we plane a revamp to increase the drive performance without any negative impact on its reliability?” Answering questions like those above is always difficult. Any assistance in answering them is therefore very needed and very welcome. The first part of the contribution describes how to create and how to provide necessary information to fill in the input document DDA Input Data Sheet that is necessary for the DDA analysis. The basic idea is to find a model of the mechanical drive system from drawings and/or other available mechanical data. It is sometimes difficult to find all relevant data in drawings, but for these cases it is relatively easy to measure dimensions and calculate the values. However the correctness of the data provided should be verified by measurements in any case because the quality of the analysis is strictly dependent on the quality of the input data. The second part of the contribution is about practical demonstration of DDA abilities. There is a simulation model of a rolling mill stand electromechanical drive. The mechanical part of the model has 3 degrees-of-freedom, i.e. 3 rotating masses. A 6-puls DC converter powers the DC motor. Even though DDA tool is a brand-new engineering software, it seems to be a good and a very promising tool for simulation and pre-commissioning of electromechanical drive systems. It is one way of many how ABB tries to help its customers in meeting their goals and requirements as close as possible |
