Motion Simulators

Motion simulators are used to calibrate rotation rate, acceleration and position sensors. Thanks to the highly accurate, uniform rotational motion of the axes, they can be used for the calibration of gyroscopes, acceleration sensors and inertial measurement units (IMU).

Sensor units which have been calibrated using Acuitas motion simulators can be found in different applications across a range of sectors.

surveying boreholes
self-driving cars
consumer electronics (mobile phones, VR glasses, etc.)
navigation of all types of vehicle (undersea, land and air vehicles, etc.)

Series overview

Thanks to its modular design, Acuitas is able to offer a wide spectrum of different motion simulators, from single-axis rate tables with a flat table top up to 3-axis motion simulators with customer-specific test piece holders and temperature chamber.

All components and the design have been created to ensure maximum mechanical rigidity and accuracy.

The unique Acuitas feature of integrating both the control system and electronics into the device itself permits reduced start-up times and simple handling.

Acuitas drives:

rate of rotation of 0.0001 to 10,000 deg/s
position accuracy of up to <=± arcsec RSS or <=± 3 arcsec PP
orthogonality up to <=±3 arcsec PP
bandwidth up to 100 Hz

wobble up to <=± 1 arcsec RSS or <=± 3 arcsec PP
payload weight up to 100 kg
temperature range from -60°C to 125°C

Single-axis series

Motion simulators with one single axis of rotation are typically used for single-axis sensor units (acceleration and rate of rotation sensors, etc.). They are available in different sizes and designs.

Other environmental influences can be simulated by combining the device with a freestanding temperature or climate chamber.

Two-axis series

Designed for applications in which simultaneous motion in two different axes is simulated. The axial orthogonality is a key dimension when specifying multiple-axis systems.

For multiple-axis motion simulators, temperature chambers mounted on the axis of rotation are used.

Three-axis series

Three-axis motion simulators are designed for applications in which simultaneous motion in three different axes need to be simulated. Axial orthogonality is a key feature.

These systems can also be used in conjunction with temperature chambers.
