Futek Application 314: Hinge Testing

Application Summary

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.

Products in Use

FUTEK’s TFF400 Reaction Torque sensor paired with Instrumentation (USB220, IAA Amplifier). For more in-depth analysis of hinge performance, a TRS605 Rotary Torque Sensor with a built-in encoder paired with a USB520 can be used. View Product Details

 How it Works

1. The TFF400 torque sensor is mounted in line with the motor driving the automated cycling system.
2. Although the TFF400 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 TFF400 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 TFF400 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 TFF400 paired with a USB220 can output the results of testing to a PC for data capture and analysis.
7. Additionally, a TRS605 paired with USB520 will allow for the logging of rotary angle data, enabling a study of torque versus hinge angle.

Futek Application - Trackpad / Touchpad Test Stand

Application Summary

A system is defined by its weakest link. Even something as small as the feel of a trackpad is scrutinised to make sure it delivers optimal performance to the end user. In this application, FUTEK’s LSB200 is fixed onto a testing actuator to record tactile feedback, run cycle test and quantify the force required to stimulate touchpad response.

Products in Use

Miniature S-Beam Jr. (LSB200) paired with Instrumentation (USB220).

How it Works

1. Trackpads / Touchpads are a common feature of desktop computers and laptops.
2. FUTEK’s LSB200 is fixed onto a testing actuator to quantify the force required to stimulate touchpad / trackpad response.
3. During R&D, a test stand can be set up to record the force of pressing and dragging motion of a finger in relation of the position on trackpad.
4. During quality checking processes, the gantry setup can be automated to inspect each trackpad to make sure the tactile feedbacks of a trackpad are within tolerance.
5. These force measures can be streamed to a computer for control and analysis utilising FUTEK's USB Solutions.
