Problems solved by technology
[0002] Fatigue life is a key indicator of automobile leaf springs. The original testing machine is mechanical and can only set the vibration stroke. If it breaks during the test, it cannot be automatically shut down, and it cannot be tested according to the specified load.
These problems affected the accuracy of the test results
And there are certain security risks
It is even impossible to set the test index, and it will automatically shut down after the test is completed

The invention discloses a steel plate spring fatigue testing system, which comprises a detecting and testing machine, and is characterized in that the detecting and testing machine is controlled through a PLC control system, and the PLC control system is electrically connected to a force measurement sensor, a pressure transmitter, an HMI (Human-Machine Interface), a counting parameter setting module and a force measurement parameter setting module; the counting parameter setting module and the force measurement parameter setting module are set through the HMI, the PLC control system is electrically connected to a real-time data display module, an alarm module and a switch control module and displays real-time parameters through the HMI. The steel plate spring fatigue testing system sets corresponding counting parameters and force measurement parameters through the HMI, and can achieve an effect of monitoring a force value in real time through comparing a pressure signal detected by theforce measurement sensor with a set value. In addition, the steel plate spring fatigue testing system can perform automatic counting and judges that a spring is broken when the force value tested inreal time is less than the preset value, and the PLC control system controls the alarm module to give out an alarm and shuts down automatically through the switch control module.
Description
Technical field [0001] The invention relates to the technical field of leaf spring test and detection, in particular to a leaf spring fatigue test system. Background technique [0002] Fatigue life is a key indicator of automobile leaf spring. The original testing machine is mechanical and can only set the vibration stroke. If there is a break during the test, it cannot be automatically shut down, and it cannot be tested under the specified load. These problems affected the accuracy of the test results. And there are certain safety risks. It is also impossible to set test indicators, and it will automatically shut down after the test is completed. Summary of the invention [0003] In view of the above shortcomings, the purpose of the present invention is to provide a leaf spring fatigue testing system. [0004] In order to achieve the above objective, the technical solution provided by the present invention is: [0005] A leaf spring fatigue testing system includes a testing testi...
