Load Application System Design Load System Concept Comparison: Cost Power Screw Gear Box System: ~$1,000 Chain Drive System: ~$600 Electrohydraulic (EHA) ~$2,500 Pneumatics ~$1,000 (Static) ~$2,000 (Dynamic) Piezoelectric >$20,000 Size Load Capability Load Accuracy Either option will take up a considerable amount of space. Gearbox consolidates the chain drive system into a box, but will still exceed space requirements of both the EHA and Piezo systems. User preset Static Loading Only, will fulfill PRP requirements for load magnitude. Load accuracy will depend directly on gear reduction through chain drive or gearbox, and operator ability. Once preset, load should be locked in and remain the same for test duration. EHA is a selfcontained hydraulic actuation unit, thus having a much smaller footprint than the power screw system. The units will require custom mounting blocks and spacers due to their length. Larger than piezos. Can statically load to PRP requirements. Some minor (slow) dynamic loading may be possible with proper control system. Load accuracy is marginal at best just in the nature of how the units are designed. They are meant for tilt displacement rather than for accurate load replication. Pneumatic cylinder occupies roughly the same space as EHA units and will require slightly larger brackets. Mounting is more ideal for load application. Will be able to statically load to PRP requirements. Load capability is in direct relation to available air pressure feed and piston size. Some dynamic ability if proportional regulators added. With a regulator, user input and regulator accuracy affect load accuracy. Once set, load will remain constant for test duration. Smallest footprint of all load actuation systems. Fast enough reaction time to replicate simulated ESH-1 compressor load profile. High load magnitude capabilities. Highest load accuracy of all load actuation systems in both static and dynamic load profiles. 11

Repeatability Controls/User Interface Availability Power System Power Screw Since this system only delivers static loading. Test repeatability will be in direct relation to load accuracy. (see above) Manual lever to turn the gear box or chain drive assembly to load preset. Could be automated with servo motor. McMaster Carr parts, high availability. Purely mechanical, no additional power system required (exception: servo motor). Electrohydraulic (EHA) Oil heating during testing could affect load accuracy and repeatability. Monitored and controlled through the PLC. Proper relief/check valve calibration will be critical. PLC (programmable logic controller.) Programming (coding) will be the challenge here. Usability will be simple inputs. Would also allow for a closed loop feedback system. Parker Hannifin. Parts and service readily available, though not simple McMaster Carr items. Power amplifier necessary for Servo motor (load based) power needs. Pneumatics Again based on user-input and regulator accuracy and repeatability. Regulator and actuator calibration will be critical. No electronic user interface. Manual mechanical control via knob on regulator and the pressure dial gage make up the entire control system and user interface. (Static case) Dynamic option would consist of a proportional regulator. Parker Hannifin. Parts and service readily available, Regulators available through McMaster Carr. Air feed line into room or standalone air compressor. Piezoelectric Highlight of the piezoelectric system is the ability to provide an accurate dynamic load profile at a high level of repeatability. PLC. More advanced coding than EHA option. Simple user inputs. Cutting edge technology, made to order systems contribute to high costs and long lead times. Power amplifier needed for powering piezos themselves as well as necessary control system. 12

Force (N) Force (lbs) P14453 RIT MSD I Detailed Design Review Decision Summary: This project called for the design and build of a dynamic similarity journal bearing test rig. With the available budget of $5,000 the dynamic aspect is not feasible. Electro-hydraulic actuators (EHAs) were considered for their compact size and self-contained design. They were later dismissed due to their lack of control, high power requirements, and high cost. Remaining static options were a mechanical system in the form of a gearbox or chain drive power screw systems, with the gear box or chain drive being implemented for gear reduction, and a pneumatic system. Chain drive was dismissed due to space requirements, leaving the gear box and pneumatic options. Pneumatics were chosen due to their simple analysis, control, and low cost. The cheapest and simplest dynamic option would be an upgraded version of the static pneumatic system, replacing the manual control air regulators with proportional regulator units. This would provide simple dynamic load profiles but minimal control. The more load system control desired, the higher the cost. This is evidenced by the ideal dynamic load system; piezoelectric actuators, providing high load capability and control in both static and dynamic load profiles. The piezoelectric load actuation system was dismissed due to system cost far exceeding the project budget.

Butt it up against the largest shaft diameter. f) While holding the support bearing in place, slide the test assembly onto the largest shaft OD, being mindful not to nick or ding the journal bearing. Be sure that the mounting point for the horizontal actuator is aligned properly. g) Slide the expansion support bearing [7] over the end of the shaft, butting it up against the largest OD and capturing the test housing between the two support bearings. h) Set the assembly on the table, with the support bearings on the support bearing risers and the slots in the bearings centered above the threaded holes in the risers. i) By hand, install the (4) 5/8-18 hex head cap [26] screws with (4) 5/8 washers [27] into the holes. j) Tighten the two bolts in the non-expansion bearing to 25 lb-ft, then 50 lb-ft, 75 lb-ft, and finally 100 lb-ft. 56

k) Ensuring that the expansion bearing is still aligned by carefully and slowly spinning the shaft. If the shaft spins freely, tighten both expansion bearing screws in the same manner used for the non-expansion bearings. l) Screw the high-load load cell [21] into the underside of the test assembly. m) Screw the low-load load cell [22] into the side of the test assembly. 7) Motor Installation: a) Set the vibration dampening mat [30] onto the table, aligning its holes with the motor mounting holes. b) Set the motor [1] on the dampening mat, aligning the mounting slots with the holes in the mat and table. c) By hand, install all (4) 5/16-18 hex head cap screws [28] with (4) 5/16 washers [29], ensuring that the motor is still free to move horizontally. d) Install the shaft coupling [3] onto both the motor and test shaft, ensuring that it is oriented such that the larger counter bore is aligned with the shaft and the smaller with the motor. e) Torque the motor mounting screws to 10 lb-ft. 8) Vertical Actuator Installation: a) Thread the vertical actuator coupling [49] onto the end of the vertical actuator [5] shaft. b) Fully compress the actuator. c) Align the vertical actuator mounting holes with the threaded holes in the risers on the underside of the table. d) By hand, thread in the (4) 9/16-12 socket head cap screws [52]. e) Torque each screw to 25 lb-ft. f) Torque each screw to 45 lb-ft. g) Torque each screw to 64 lb-ft. h) Carefully extend the vertical actuator and thread the coupling into the corresponding load cell. 9) Horizontal Actuator Installation: a) Set the horizontal actuator angle mount [48] on the table, aligning it with the threaded holes in the table. b) By hand, thread the (4) ¾-16 hex head cap screws [24] with (4) ¾ washers [25] into the holes. c) In turn, torque each screw to 100 lb-ft, be sure to tighten the bolts incrementally in a distributed pattern in order to ensure the load is evenly distributed. d) Thread the horizontal actuator coupling [50] onto the end of the horizontal actuator [6] shaft. e) Fully compress the actuator. 57
