DATES TO BE ANNOUNCED
This course is designed to cover all aspects of bushing design and engineering for both automotive and commercial applications. It’s a the perfect introduction for a new engineer to learn basics of rubber bushings as well as seasoned professionals to pick up some new tips.
The course includes an actual natural rubber production recipe, with many photos and examples of inner metals and outer metals along with detailed drawings presented. A large portion of the class focuses on fatigue testing past and present with discussion of rainflow data, block cycle testing and actual Wohler J curves derived by the author. Class participants will also explore:
- Dual durometer and hydraulic bushings with an actual take apart bushing shown.
- Static rate calculations with results compared against FEA and real-world testing.
- Static and dynamic tests, vehicle natural frequency, NVH and road data.
A section on drawings showing different bushing constructions concludes the class.
This course can be applied to the following certificate:
Elastomer Technology Certificate
