英文摘要：

The torque sensor is one of the core components used by intelligent bicycles. A Lab VIEW-based automatic testing system for torque sensors is introduced in this article. Motor, magnetic powder brake, temperature humidity chamber and other lower computer equipment which controlled by Lab VIEW realize the dynamic testing of temperature and voltage. On the basis of curve fitting, a PAM（performance assessment model） is put forward to reflect durability and thermo-sensitiveness of the torque sensor. The model can simulate and predict performance curves of the torque sensors under different temperature and time duration. It has been verified by experiments that the prediction model has high prediction accuracy and prediction stability, its test error is less than ±2%. The system provides a solution for automatic test of the torque sensor and helps to reduce the test cost and further optimize the design of the torque sensor.
