The Design of Smart Snap Ring Torque Measurement System
Abstract: The important working parameters of the rotary power machine are torque, but torque measurements have been made in an important part of the mechanical measurements. If accurate, reliable and easy to carry out the average or instantaneous torque, speed and mechanical power of the test, it is helpful to improve and improve its performance. Torque detection is a common method for measuring the performance of mechanical products, and it is also a kind of testing method which is often used in scientific research. Subject to uses high precision strain gauge sensor, data acquisition and analysis technology design a small range, convenient and easy to use intelligent card ring type torque detection device for torque detection apparatus, is a more advanced, and accuracy, and has important research value and application value. According to the functional requirements of the ring type torque sensor smart card, card ring type torque sensor working principle, design based on wireless digital transmission control circuit, analog sensor signal acquisition circuit, data acquisition and span adjustment circuit, man-machine interface circuit design is analyzed.
