Single-Axis Linear Motion Calibration System with Control Software

The U.S.

Food and Drug Administration requires one (1) complete, turnkey single-axis (one degree-of-freedom) linear motion calibration system, commonly described as a shake table, with control software, for laboratory calibration, verification, and validation testing of inertial measurement devices.

The system shall be fully assembled, factory-tested, and factory-calibrated prior to shipment, requiring only unpacking, cable connection, and software installation by the end user.

The Government seeks sources able to provide a system meeting, at minimum, the following salient performance characteristics.

These are stated in approximate terms for market research; the full minimum specification will accompany any resulting solicitation. • Programmable single-axis linear motion under closed-loop position control with real-time feedback, capable of arbitrary user-defined waveforms including multi-frequency superposition of at least three simultaneous components.

Pre-programmed, fixed-routine-only calibrators are not sought. • A motion envelope on the order of 0.1 to 10 Hz in frequency, sub-millimeter to approximately twenty millimeters in displacement, and up to approximately one g in acceleration, with demonstrated small-amplitude positioning accuracy at the sub-millimeter level. • An integrated position sensor and an integrated reference accelerometer, each factory calibrated with NIST-traceable certificates. • Safety features including a hard-wired emergency stop, motion limits, over-current protection, and fault detection with automatic safe shutdown. • Benchtop form factor suitable for standard laboratory power (110 to 120V, or universal input) without special power conditioning or floor reinforcement. • Control software operable in a standalone configuration with no required internet, cloud, or subscription, a programmable interface compatible with MATLAB, Python, or an equivalent industry-standard environment, and non-proprietary data import and export. • Software and electronic content conforming to Section 508 accessibility standards, supported by a Voluntary Product Accessibility Template or equivalent.
