Vibration
Analysis Software
Description
Analyze vibration of cars: Noise levels for comfort, quality
Simulation models needed; physical prototypes not practical
Detailed (huge) model needed Historically, Cray supercomputers
were required: Expensive Slow job turnaround Limited benefit
from analysis.
New numerical algorithm: Divide and conquer
Thousands of substructures Automated multilevel substructuring
(AMLS) Reduction via small substructure problems Fits into
industry standard software
Benefits
- Jobs run faster
- Cheaper computers can be used
- Lots of cheaper computers
- Analyst sees quick turnaround
- Broader frequency range, more analysis
- Better design (quieter cars)
- Lower cost, better product
Features
- Standard code
sleeps while AMLS does? heavy lifting? and returns results
- Use of AMLS is transparent to user
- AMLS requires much less disk space
& I/O
- Uses multiple processors efficiently
- Results are very accurate
Market Potential/Applications
