Space Mountain at Euro Disney: A 120 million dollar wire rope test machine
Round Table The Application of Endurance Prediction for Wire Rope – Reading
The service conditions of the ropes from the Space Mountain rope-drive at Euro Disney are discussed. These ropes are discarded after about 3 months and 120,000 catapult operations, a figure which was predicted in the design phase using modern wire rope endurance prediction methods. Every rope section is subjected to the same conditions every 36 seconds, the mode of operation never changes. Some rope sections are only subjected to tension-tension fatigue, others to tension-tension and bending fatigue. Daily visual rope inspections and magnetic rope testing at regular intervals, as well as destructive rope tests after discard, provide an enormous amount of "real life" data which has been compared with the theoretical predictions. The paper also presents a method of determining the most favourable length of rope to slip and cut and discuss the results of this procedure.
