Vibration Isolation via Decoupling & Other Design Factors
No longer is vibration-absorbing materials the best way to reduce vibrations. Instead, tests have shown that a PROPERLY designed custom-molded steering wheel grip ISOLATES the driver from the source of vibration and DECOUPLES him/her from the source. Accelerometers glued onto test subjects' fingernails proved this new mode of vibration attenuation is FAR superior since transmitted vibration is what matters.
He talks about thinking in 4D: x, y, z, and TIME. The time factor involves both the cross-linking time involved when molding thermoplastics, as well as the highly iterative evolutionary aspect of the design process itself as drivers sort their steering wheel grips over a period of weeks, or even months.
Training time is also necessary to get the drivers to be compliant with the technology and start using it properly. This is important since we are all creatures of habit, and old habits must be be broken to reap maximum benefits.
The last time factor involves respecting both the team's and driver's schedules and learning how to ask the right questions in a minimum amount of time to get the information needed to design the grips to perfection.
