Single load-disk main shaft loading method for testing performance parameters of numerical control system

The invention discloses a single load-disk main shaft loading method for testing performance parameters of a numerical control system. The method adopts a design principle that: a homogeneous disk of certain quality and size is loaded on a motor main shaft of the numerical control system, and G codes are written into the numerical control system, so the loading condition of the numerical control system under the operation condition can be realized conveniently and simply; and for the motor main shaft of the numerical control system, loading of a motor in a constant torque section and a constant power section is realized, and testing of the performance parameters of the numerical control system is finished. By adoption of the method, the loading condition of the numerical control system under the operation condition can be realized conveniently and simply.
