Building and managing a theme park is clearly focused on visitor safety. MoreVision are often called to assess the strength, fatigue strength and safety of new attractions.
The Hong Kong Disneyland Railroad Vehicles
The Hong Kong Disneyland Railroad vehicles carry guests between attractions on the resort and requires extensive analysis to satisfy the local regulatory bodies. The train comprises a loco, tender vehicle and coaches. Each vehicle has its own bogie and wheelsets and all items of equipment required assessment. Finite element analysis and calculations considered the static strength and the fatigue strength of the railroad vehicles. Analysis covered many combinations of vertical loads (tare to crush), longitudinal loads (braking, vehicle recovery) and transverse loads (curving, wind and slope). MoreVision worked closely with the vehicle manufacturers transferring data via the internet. MoreVision gave further support by assisting in the client design scrutiny process.
Static strength and fatigue strength analysis was required for the Main Street Vintage Vehicles in Disneyland's new Hong Kong Resort. These included a paddy wagon and a double deck omnibus vehicle.
MoreVision have done a great deal of railway bodyshell analysis but analysis for the Theme Park industry is actually more like crane design than railway design. MoreVision prepared calculations for TUV approval using German DIN standards. MoreVision were also required to take the calculations through the client scrutiny process.
The picture above shows Disneyland's 'Catastrophe Canyon' ride. A burning petroleum tanker about to falls onto a crowd of onlookers... a job for Superman? No MoreVision! We undertook a loading analysis and a stress and fatigue assessment of the wagon kingpin joint to ensure spectator safety.
Remember when Indiana Jones escaped a band of marauding natives by swimming to his bi-plane floating of a river. Disney wanted to recreate the feel of the film and bought a identical plane for use in their 'Indiana Jones and the Eye of the Temple' attraction. These planes have a take off speed of 30 miles per hour so the problem given to MoreVision was to stop the plane from taking off in strong winds. We undertook some aerodynamics calculations and designed an anchorage system for the plane.
