Embodiment
[0068] Under laboratory conditions, in order to generate a stable impact force and act for a certain period of time, the present invention chooses to use the gravitational potential energy of the falling weight to freely fall and collide to generate the impact force. Due to the short duration of the pulse force generated by the collision of rigid bodies, this test device uses the axial compression energy absorption method of metal thin-walled circular tubes for buffering. The specific energy absorption rate and stiffness of metal tubes are relatively large, and the size of the mechanism can be made small. Reduce the impact on the landing gear of the simulated experimental platform; in addition, the energy absorption process of metal pipes can be controlled more accurately, and it is easy to meet the requirements of force value and time.

The invention discloses an electric cylinder servo system with an impact test function and a control method thereof. The electric cylinder servo system includes a servo execution unit, upper computercontrol software and a lower computer servo controller. The control method includes the steps that the upper computer control software, the lower computer servo controller and a rotary encoder are connected firstly; then the upper computer control software receives a control parameter input by a user, a control instruction is analyzed and sent to the lower computer servo controller; the lower computer servo controller sends a control signal to the servo execution unit according to the control instruction; then the servo execution unit completes an impact test; and finally the rotary encoder collects the current angle of the electric cylinder servo system, the lower computer servo controller feeds a motion state back to the upper computer control software, and the motion state is displayedin the upper computer control software in real time. The inertial load, the static resistance load and the dynamic impact load in a specific form of the electric cylinder servo system can be simulated, a simulation environment and test means are provided for designers, and safety and reliability are achieved.
Description
technical field [0001] The invention belongs to the technical field of mechanical devices, in particular to an electric cylinder servo system with an impact test function and a control method. Background technique [0002] The electric cylinder servo system is a precision electromechanical integration product, which integrates the design of the servo motor and the lead screw, which greatly meets the system's precise control requirements for thrust, speed and position. As an electric actuator that provides linear motion and driving force, the main working principle of the electric cylinder is to convert the rotational motion of the motor into the linear motion of the push rod, and drive the load through the push rod to fully control the precise speed of the servo motor, Accurate revolution control and precise torque control are converted into precise speed control, precise position control and precise thrust control, and its acceleration is fast, positioning time is short, an...
