Problems solved by technology
The robot arm loading control system can realize small-scale static load application, but the robot arm loading control system generally uses multiple sets of servo motors and corresponding servo control systems to realize static load control, and its cost is relatively high, and it is very expensive. Difficult to achieve multi-channel coordinated static loading
At present, in the field of automobile manufacturing and the production of small household appliances, there are a large number of static test requirements, and the magnitude of the static load is not large, generally within 0-2000N, the test magnitude is not suitable for the use of hydraulic loading systems, and the test cost The loading system on the robotic arm is too expensive

The invention discloses a closed-loop control system of an aerodynamic force load, and aims at providing a load applying scheme for low-magnitude static force test. The system comprises a touch screen, an integrated controller, an output control module and a feedback control module. A control parameter is input in the control screen, the force load feedback control module is triggered to collect a load signal, the integrated controller compares the load signal with a target parameter and then controls the output control module to adjust the output load, and thus, finally the output load is consistent with the object load after repeated iteration. According to the system of the invention, high-precision force load control is realized, and the test cost is reduced greatly.
Description
technical field [0001] The invention belongs to the technical field of static tests, and in particular relates to an aerodynamic load closed-loop control system. Background technique [0002] Static loading test is a means to assess whether structural components meet the strength design requirements. Most structural components need static test assessment in their research and development stage, from aviation, aerospace, shipbuilding to automobile, rail transit industry to small For household appliance manufacturers, almost all products need to undergo structural strength assessment. The main purpose of structural strength assessment is to verify whether the product will undergo structural damage under its normal working environment. The relatively mature static loading systems currently on the market include hydraulic control systems and robotic arm loading control systems. [0003] The hydraulic control system mainly realizes high-level static load tests, and its system c...
