Acceptance meeting
As a key parameter of high-precision mechanical power, accurate measurement of large torque is crucial in advanced manufacturing fields such as defense, shipbuilding, and automobiles. In order to cope with the ever-increasing demand for high-torque accurate traceability and high-accuracy and high-quality measurement in China, researchers of the research team have integrated the spirit of great country craftsmen into the pursuit of technical details and have successfully developed independent intellectual property rights over the past four years. High accuracy and high quality parameter measuring device.
According to Wang Jian, a researcher at the Institute of Mechanics and Acoustics at China Institute of Metrology, the subject is one of the tasks of the project “Development and Application of Torque and Velocity Measuring Instruments for High-end Power Devices†for the development of major scientific instruments and equipment in the country. The device developed by this project has a high degree of instrumentation and high reproducibility. The full-load repeatability is 0.15 g, the sensitivity is 1.27 g, and the measurement uncertainty is 3.6 g (k = 2). It has entered the world's advanced ranks. It is praised as "the exquisite design and technological innovation of China's large-scale standard measuring devices."
2000 kg high accuracy large mass parameter measuring device
At the same time, the research group independently designed and developed the “National Special Scientific Information System for the Development of Scientific Instruments and Equipment†for the first time, realizing real-time management of projects and tasks in terms of financial implementation, technical data, research and development progress, and research results, and for each task. Provides an information exchange platform in different places to ensure the efficient and standardized management of the project.
(Original title: Development of a national project for the development of a major scientific instrument and equipment "High-accuracy, high-quality parameter measuring device" subject acceptance)
[China Instrument Network Instrument R&D] A few days ago, China National Institute of Metrology (hereinafter referred to as "China Institute of Metrology") took on the task of the National Major Scientific Instrument and Equipment Development Project II: "Development of High Accuracy and High Quality Parameter Measurement Device" acceptance. The project succeeded in developing a measuring device with a maximum measuring range of 2000 kg with high accuracy and high quality. The parameters such as repeatability and sensitivity far exceed the internationally existing commercial measurement device technical target, and China's large-scale measurement calibration measurement capability (CMC) is achieved. Raise to second in the world.
