Kiểm tra độ bền của bản lề dùng cảm biến Momen xoắn (Hinge Fatigue Testing)

Torque hinges, friction hinges, and position hinges are all synonyms for a type of hinge that allows two parts to rotate about one another when a load is applied. The hinge then returns to its original position when that load is removed due to its high torsional stiffness. Because of this property, they are used in everything, from cabinetry and car glove boxes to laptops and monitor stands. This wide range of uses requires that these hinges survive and very often exceed the lifetime of the product. To ensure this, fatigue and cycle testing must be performed to verify the hinge lifespan when integrated into the product.

How it Works
  1. The DH-15 torque sensor is mounted in line with the motor driving the automated cycling system.
  2. Although the DH-15 is a reaction torque sensor, if the overall rotation is less than 360 degrees, you avoid the risk of the cable winding around the sensor.
  3. The DH-15 is then mounted to the hub of a wheel. The rotation of the wheel will allow the hinge that is to be tested to open and close.
  4. The DH-15 will then record the amount of torque needed to open and close the hinge.
  5. If the motor is set in brake mode, the torque sensor will be able to measure the torque spring resistance and torsional stiffness.
  6. A DH-15 paired with a LCV-USB3 can output the results of testing to a PC for data capture and analysis.
