2. Value Engineering in a Manufacturing Facility
Objective:
Design and build a safe compressor final internal assembly stand for the Olean Manufacturing Facility.
Key Needs:
Adjust to different sized compressors. [Length (35”-86”) and Diameter 21”-43”)]
Be able to support up to 30,000lbs for a week.
Support different sized Heads
Work bench to support assembly tools

3. Current Process Head Pipe Clamps to Support Head Top Half is Removed
During Final Assembly
Bundle
Cradles
Complete Bundle on Contract Tooling

4. Professional Engineer Certification
Need for PE Certification – Dresser-Rand must use outside source
Working with Dr. Hensel to find a PE
Bridging contract between PE and Dresser-Rand

5. Final Design Sub Systems: Compressor Stand Tool table
(refer to page 1)

6. Ergonomics
Picture illustrates work surface height relative to person 5’5” (5th percentile male) in stature.
Body part lengths provided by NIOSH anthropometric tables
(refer to page 27)

7. Compressor Stand System Design
Highlights:
Adjustable V and length using track system
Supports optimum height work level
Risks/Concerns:
Ergonomics of smallest compressor
Play in Pin Holes
Track stress while compressor loading or adjusting
Tool Table joints
(refer to pages 1-6)
                                                

8. Adjustability System:
Length Adjustment System:
Versa Mount guide block and rails
Mounted to stand crossbeams
3000lbs dynamic load per mount
Adjust length using boom crane
Diameter “V” Adjustment System:
Pinned V-hold
Low friction sleeve for ease of height adjustment
Adjust for different size compressors to accommodate work envelope

9. Analysis and Calculation
Key concerns from the concept Review:
Strength of Diagonal “V’s”
V-Hold weld Strength in Shear
Slop in the Pins
Tools for Analysis:
Hand Calculations
Computer Software (Pro-E and Pastram)
(refer to pages 7-15)

10. Meshed Model with Forces

12. Deflection and Stress

13. Tool Table System Design13
Highlights:
Adjustable height
Able to be moved to different locations
Lip on Table Surface
(refer to pages (16- 25)

14. Adjustability System:
Joints:
Steel on Steel or Bearings for tool table height adjustment
Pins:
Press Pin
Quick release and placement
Attachable for one integrated system
Detachment from the Compressor Stand:
1 bolt attachment
Mounting holes at center and ends of stand
