Development of methods for analyzing and improving spindle units with hydrostatic supports as dynamic systems

Subject of investigation: spindle units with hydrostatic and other supports (hydrostatic and rolling supports). The theoretical results of the work include the development of a method of constructing and analyzing a generalized model of a closed dynamic system of the machine which accounts for the interaction of the elastic system of the machine and the working processes, and the development of a model of the spindle unit with different supports (hydrostatic supports and rolling supports) which provides for making a detailed analysis of the influence of the design parameters on the dynamic quality. Developed are methods of simulation modelling and identification of dynamic objects which include mechanical elements and elements of other types, as well as the respective software. The results of the work were used in the development of a spindle unit of a horizontal boring machine, model 2P637F4. The results of the investigation provide for a higher vibration resistance and efficiency of the machinesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
