- Flat, disc-shaped design
- High pulsating and alternating loads
- Robust design
- Overload protection
Measuring task
Flight simulators with a total weight of approx. 12 tonnes must be securely mounted to the floor with their driven supports in the foundation. Their flexible movement in space creates pulsating loads in all three axes on the connecting elements to the foundation. The forces occurring must be measured in order to develop and monitor safe brackets and clear installation procedures.
Special requirements
The sometimes jerky movements of the drives - for example when simulating turbulence - result in high pulsating and alternating loads. Unavoidable transverse loads on screw connections must be absorbed for the measurement. Different materials to be connected, such as steel and concrete, also result in manufacturing tolerances that need to be compensated for.
Solution
A model 8438 ring load cell is integrated into the fasteners to measure the forces occurring in the clamping screws and not least in the dowel materials in the concrete. The ring load cell model 8438 is securely installed using surrounding mechanics such as a centring sleeve and sensor support. The ball socket/ball disc combination ensures even load distribution around the circumference of the load cell. To prevent mass grinding in the system, we recommend using an insulating disc in a suitable position.
