Reliability of New High Tech Roller Coasters By: Topher Schott DSES-6070 HV5 Statistical Methods for Reliability Engineering Spring 2008 Professor Ernesto Gutierrez-Miravete

What could go wrong in a roller coaster? Launch Track Urethane Wheels SensorsMagnets Brake Runs Lift Hill Train Track Inversion Launch Track

Reliability of Launch Tracks Hydraulic Linear Induction Motor “[Many new coasters] rarely open during its first season” “Many of these rides ran reliably once the kinks were worked out…”

Methodologies for Project Event Tree Fault Tree Monte Carlo Simulation FMECA Assumptions: Wind/Weight/Precipitation Distribution Momentum> ft lb per second Momentum negatively proportional to Wind/Precip Goal; Least “Maximum Speed” required?

Results The greater the maximum speed capabilities, the better availability of the coaster!

Conclusion How do you make these go faster? What is a failure to the end customer? Complete FMECA used to prevent catastrophe
