Continuous-casting crystallizer vibration simulation test unit and non-sine vibration control method thereof

The invention provides a continuous-casting crystallizer vibration simulation test unit and a non-sine vibration control method of the continuous-casting crystallizer vibration simulation test unit, and belongs to the technical field of ferrous metallurgy continuous-casting crystallizer simulation application. The continuous-casting crystallizer vibration simulation test unit comprises a main control computer, a controller, a motor driver, a stepping motor, an eccentric wheel, a connecting rod and a vibrating plate used for simulating a continuous-casting crystallizer copper plate. The non-sine vibration control method of the continuous-casting crystallizer vibration simulation test unit comprises the following steps: vibration speeds of the vibrating plate at all moments in the non-sine vibration process are set; the set vibration speeds of the vibrating plate at all the moments are converted into vertical velocity components of the eccentric wheel at all the moments, so that rotation speeds of the eccentric wheel at all the moments are obtained; rotation speeds of the stepping motor at all the moments are obtained, and the controller controls the stepping motor to rotate at the rotation speeds at all the moments through the motor driver; the stepping motor drives the eccentric wheel to rotate in real time and then drives the vibrating plate to conduct non-sine vibration. According to the continuous-casting crystallizer vibration simulation test unit and the non-sine vibration control method of the continuous-casting crystallizer vibration simulation test unit, a mechanical drive mode is adopted for realizing non-sine vibration, a piecewise function method is adopted for establishing a velocity curve, and therefore vibration technological parameters are easy to acquire.
