Pendulum impact tester control system and control method thereof

Abstract

The invention discloses a pendulum impact tester control system. The pendulum impact tester control system comprises a tester, a controller and a frequency conversion driving device, wherein the frequency conversion driving device is connected with a driving motor and a speed detection device; the controller is connected to an industrial Ethernet switchboard; the industrial Ethernet switchboard is connected with a remote operation computer and a field operation panel respectively; the controller is connected with a position detection device; the invention further discloses a control method of the pendulum impact tester control system; the control method comprises the following steps of: (a) pre-setting an impact energy value; (b) automatically calculating a target lifting position value; (c) carrying out positioning control on a lifted pendulum; (d) carrying out speed control on the driving motor; (e) carrying out torque control on the driving motor; (f) carrying out current control on the frequency conversion driving device; and (g) outputting current to the driving motor. Only if one data is simply input through the field operation panel, a lifting mechanism can be fully automatically and accurately positioned and a whole process does not need manual intervention.

Description

Technical field [0001] The invention belongs to the field of automation technology, relates to a mechanical control system of an impact machine test platform, in particular to a pendulum impact test machine control system and a control method thereof. Background technique [0002] Horizontal impact testing machine is an instrument for testing the impact resistance of metal materials under dynamic load. It is widely used in metallurgy, machinery manufacturing and other units. It is also an indispensable testing instrument for scientific research units to conduct research on new materials. [0003] The working principle of the horizontal impact tester: The impact tester uses the potential energy of the pendulum to impact the sample with one drop. The pendulum is the impact mechanism of the impact machine. Its function is to strike the tested material and is an important part of the impact test platform. The pendulum is centered on the pendulum axis of the impact testing machine, an...
