Braking Systems: Controlling Speed and Safety
Rollercoaster braking systems are key to managing speed and keeping riders safe. There are different types of brakes used, each with its own role. Friction brakes slow trains down by making physical contact. They are dependable but need replacing over time.
Modern coasters often use magnetic brakes for a smoother stop. These brakes slow trains down with magnetic fields, cutting down on wear and tear. Eddy current brakes, a type of magnetic brake, use fins to control speed efficiently.
Trim brakes are vital for rollercoaster design too. They adjust the speed during the ride for a better experience. By controlling the coaster’s speed, trim brakes make the ride thrilling yet safe. For instance, the Stromag’s Spring-Applied Multi-Disc Brake NFF can apply up to 10,000 Nm of braking torque.
Braking technology has made rollercoasters safer and more exciting. The global hydraulics market was worth £37.4 billion in 2020. This shows how investing in better braking systems keeps the amusement park industry moving forward.
Launch Systems: Accelerating the Thrill
Roller coaster launch systems have changed the game, bringing new thrills. The hydraulic launch, seen in rides like Kingda Ka, uses pressurised fluid for a fast start. Formula Rossa at Ferrari World hits 149 mph in just 4.9 seconds, showing off this tech.
Linear induction motors are another way to speed up. They were first used in 1996 on Flight of Fear at Kings Island. These motors use electromagnetic fields for a smooth start. The linear synchronous motor, found in Superman: The Escape at Six Flags Magic Mountain, also hits over 100 mph.
Compressed air launches are the most powerful. Dodonpa at Fuji-Q Highland uses this method, reaching 106.9 mph in 1.8 seconds. Engineers use a formula to work out these speeds. It includes acceleration, initial and final velocities, and time.
