In recent years, with the rapid development of high-speed EMU, high-speed rail has become the mode of transportation chosen by most people in our country.
The running speed of high-speed rail is up to 350Km/h, and catastrophic accidents will occur if accidents such as shaft cutting and wheel collapse occur. Therefore, it is very necessary to regularly test the wheelset in the process of operation to ensure driving safety, and non-destructive testing is an important means to find potential hazards such as fatigue cracks in the wheelset maintenance.
The maintenance department of high-speed railway will regularly test the wheelset according to the running mileage of high-speed EMUs, and adopt ultrasonic automatic detection equipment to test the wheelset without disassembling the brake disc. Before automatic detection, the equipment needs to be calibrated and debuted. Therefore, the quality of the calibration test block directly affects the detection performance of the automatic detection equipment, affecting the operation safety of high-speed rail, relying on the artisan spirit and enterprise philosophy of "blessing safety, Ruixiang loyalty", Ruixiang people have won the recognition of the railway system experts with the attitude of doing a good job of each individual injury and doing a good job of each piece of test block.
The high-speed rail wheel set calibration test block produced by the company is not only widely used in various high-speed rail maintenance workshops in China, but also serves the German high-speed rail maintenance across the ocean.
