- Description
- 8. The purpose of this amendment is to clarify the specifications (in bold) due to questions received from potential offerors and extend the response date as follows: (vi) Description of requirements: SPECIFICATIONS: The Contractor shall provide a system to calibrate optical sensors and accelerometers that are imbedded in various test bodies. The Contractor shall ensure the system employs a 3-stage assembly to manipulate the horizontal position and the orientation (roll and yaw) of these transducers with respect to either a horizontally-projected collimated solar-equivalent light source or the earths gravitational field. The 3-stage assembly shall include (a) a motorized rotation stage in a vertical configuration (roll) to which a test body is attached, (b) a motorized rotation stage in a horizontal configuration (yaw) attached to an optical table, (c) a manual linear stage mounted between the roll stage and the yaw stage to manipulate the horizontal position of the roll stage and the test body with respect to the center of the yaw stage, and (d) appropriate brackets, couplings, and mounting fixtures. The Contractor shall ensure that the orientation of the transducers (optical sensors and accelerometers) embedded in a test body are manipulated by driving the roll and or yaw rotation stages. The Contractor shall attach one end of the test body (the base) to a table on the front face of the roll rotation stage, using fixtures which the Government will provide as Government Furnished Property (GFP). Thus, the test body shall extend horizontally from the front face of the roll stage and the front face of the roll stage is the upper surface in a horizontal configuration. The Contractor shall ensure that the system meets all of the following salient characteristics: A. ROLL STAGE: The Contractor shall ensure that the roll stage controls the roll orientation of (a) optical sensors with respect to the collimated light source, and (b) accelerometers with respect to the earths gravitational field. The Government will set the height of the light housing so that the height of the center of the roll stage is at the vertical center of the collimated light path. The Contractor shall ensure that the roll stage includes a second table on the rear face with provisions for mounting a wireless data acquisition system and transmitter, battery pack(s), and counter weight(s). The estimated weight of these items are 5 10 pounds in a balanced load mounted to the rear table top (mounting holes and small aperture hole are required). The Contractor shall ensure that the rear table is attached to, and moves with, the front table. The Contractor shall ensure that the roll stage includes an aperture for wires to carry power and signals between sensors on the test body and the power and data acquisition components on the rear table. The Contractor shall mount the roll stage on the top of the linear stage using a bracket that provides clearance between the largest diameter test body and the linear stage. The Contractor shall ensure that the Roll Rotation Stage also meets the following Salient Characteristics: Motor Type: Direct drive; no gears in the drive mechanism. Travel: 360 degree continuous (with removable limits and hardstop). The Contractor shall ensure the user has the capability to define the limits (1 revolution, 2 revolutions, etc). Resolution: better than 0.001 degrees Accuracy: better than 0.01 degrees Repeatability: better than 0.001 degrees Rate: 0 to e60 rpm Mounting Faceplate fixtures must bolt to 8 in. diameter plate with bolt pattern. Encoder: Continuous travel Other: Must be upgradable to low noise slip rings (approx 24 lines). No electrical connection to the table top is required. B. YAW STAGE: The Contractor shall ensure that the yaw rotation stage controls the yaw orientation of the optical sensors with respect to the light source. The Contractor shall position the center of the yaw stage beneath the horizontal center of the collimated light path. The Contractor shall mount the bottom of the yaw stage on a plate that is fastened to the top of the Government owned optical table. The Contractor shall ensure that the Yaw Rotation Stage also meets the following salient characteristics: Motor Type: Direct drive; no gears in the drive mechanism. Travel: 90 degrees (with removable limits and hardstop) Resolution: 0.001 degrees Accuracy: 0.01 degrees Repeatability: 0.001 degrees Rate: 0 to e6 rpm Encoder: Continuous travel C. LINEAR STAGE: The Contractor shall ensure that the linear stage (a) positions the optical sensors on the test body approximately above the center of the yaw rotation stage to minimize changes in distance between the light source and the sensors during roll and yaw manipulations, and (b) keeps the center of gravity of the test body and roll stage assembly as close as possible to the center of the yaw stage. The Contractor shall orient the linear stage to allow manipulation of the horizontal position of the roll stage and the test body. The Contractor shall adjust the position of the roll stage on the linear stage according to the distance between the optical sensors and the front face of the roll stage. The Contractor shall mount the bottom of the linear stage to the table on the top of the yaw rotation stage. The Contractor shall ensure that the Linear Translation Stage also meets the following salient characteristics: Motor Type: Manual Travel: 0 - 20 inches. Resolution: 0.25 inch/rev or smaller on hand crank The Contractor shall ensure that the assembly is able to support the following Test Body: Maximum diameter: 6 inches Maximum weight: 30 lbs Minimum distance from the center of the imbedded sensors to the front face of the roll rotation stage: 3 inches including the mounting fixture. Maximum distance from the center of the imbedded sensors to the front face of the roll rotation stage: 20 inches including the mounting fixture. Worst case load on the roll stage: A10 lb mounting fixture with cog 2 inches from the table surface plus a 30 lb test body with cog 15 inches from the table surface. The Contractor shall ensure that the system is capable of leveling the roll axis to +/- 1.0 degree from the optical table. CONTROLLER: The Contractor shall provide a PC-based controller that is programmable by LabView as well as a complete set of LabView Vis and any software that is necessary in order to render the system fully operational. The Contractor shall ensure that the motion controller is capable of linear and circular interpolation, kinematics, fast position capture, inertia damping, and end point modification. The Contractor shall ensure that controller provides position synchronized output for triggering of data collection, is capable of at least 2 axis of coordinated motion, is expandable to a higher axis count in the future, and is rack mountable. The Contractor shall ensure the user has access to the real-time encoder positions. AMPLIFIER: The Contractor shall provide Digital Linear Amplifiers with no switching noise and zero dead band. The Contractor shall ensure the amplifiers have 20 kilohertz (kHz) position, velocity, and current loop sampling. SYSTEM CERTIFICATION: The Contractor shall test and calibrate the system to the required specifications prior to delivery and shall provide a certificate of compliance. The Contractor shall test and integrate the system at the Contractors facility. The Contractor shall ensure that the set up includes controller parameter creation and system performance evaluation.
