A multi-class, three-axis high-dynamic precision rate table designed to simulate vibration and precise slow motion while maintaining high pointing accuracy. The system is frequently utilized as a Flight Motion Simulator (FMS) in Hardware-In-The-Loop (HWIL) simulation environments.
Inner roll, middle pitch, and outer yaw axes with continuous angular freedom.
Frequently utilized as a Flight Motion Simulator in Hardware-In-The-Loop environments.
Middle-axis acceleration reaches ±3,500°/s², while the outer axis reaches ±1,500°/s² and 1,274 N·m maximum torque.
Nonlinear multi-variable controller with user-friendly GUI integrated in a 36U console.
The FDA-332-HDD is intended for development, production, in-process testing, calibration, and final inspection of inertial components and instruments. The catalog specifically lists high-precision MEMS sensors at FOG performance level, medium and large INSs, IMUs and IRUs belonging to the FOGs class, as well as stabilized optical sights and star trackers.
The product is designed around three axes and three degrees of freedom. The middle-axis gimbal uses a U-shaped design to provide unobstructed optical access to the tabletop, while the middle and outer axes use stow locks to facilitate the safe loading and unloading of the UUT. Precision pre-loaded angular contact ball bearings permit load capacities of up to 25 kg. All systems are supplied with the necessary interconnecting cables and mating connectors for customer interface. Using T-Nut levelers, the rate table can be aligned in two directions.
The drive system combines direct-drive brushless torque motors, absolute optical encoders, precision pre-loaded angular contact ball bearings, a precision-machined tabletop, precision-bored bodies, and slip-ring assemblies.
Inner roll, middle pitch, and outer yaw provide three continuous degrees of freedom.
The catalog specifies direct-drive brushless torque motors as part of the high-reliability servo architecture.
Absolute optical encoders are directly mounted to the axes to provide high-precision positioning performance.
Slip rings with power rings and shielded signal rings provide electrical access to the UUT and support continuous-rotation simulation.
