Embodiment Construction
[0023] The present invention provides a high-speed motorized spindle modeling method based on a bonding graph. In order to make the present invention more obvious and understandable, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] The temperature field of the thermal error system of the high-speed electric spindle of the present invention mainly includes the bearing part, the stator part and the rotor part. The positional relationship between all bond graph models is connected with standard bond graph components, thereby constructing a complete bond graph model of the temperature field of the high-speed electric spindle thermal error system, and further establishing a high-speed electric spindle thermal error mathematical model, according to the model Carry out system simulation and analysis to obtain the size of the thermal error of the high-speed electric spindle. The main steps are as fol...
