Methodology for the development of a digital model of a mechatronic motor-spindle system for the study of its vibration resistance

Abstract

Development of digital models. A digital model represents the geometric, physical, and dynamic properties of an object. Digital models can be performed using computational experiments, developing methods for expanding technological capabilities, organizing support and implementing solutions for the comprehensive diagnostics of the technical state of the machine system and process indicators.The article discusses the methodology for creating a digital model using an example of a motor spindle of a mechatronic machine with CNC and the study of dynamic processes in a motor spindle. The basis of the digital dynamic model was the model of the mechanical part of the spindle implemented in SolidWorks CAD, which was then exported using the SolidWorksLink model translator into the SimMechanics modeling environment of the MatLab system. The adequacy of the obtained model to a real object is proved. Models of perturbing influences arising from the operation of machine equipment have been created. Tests were performed on the motor-spindle model, the influence of manufacturing errors of the motor-spindle elements on the positioning accuracy of the spindle assembly, depending on its dynamic characteristics, was estimated.
