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

Automotive - licensed through CDH AG (Small Public Germany Co.) to: Ford, Chrysler, BMW, Saab, Mercedes-Benz, Opel, Ceat, Jaguar, Volvo, Peugeot, Honda, Nissan, Subaru, Daihatsu, Mazda, and others. New markets: Aerospace, other complex structures.
