Large-scale amusement equipment The roller coaster, also known as the roller coaster, is an exciting entertainment tool, which is commonly found in amusement parks and theme parks. LaMarcus Adner Thompson was the first to register a patented technology related to roller coasters and has built dozens of roller coaster rides, so he is known as the 'Father of Gravity'.

A basic roller coaster structure includes climbing, sliding, and inversion. The design of the track is not necessarily a complete cycle, but it can also be designed so that the running mode of the car body on the track is to move back and forth. Most roller coasters have 2, 4, or 6 people per carriage, which are connected to each other with hooks, like a train.

How the roller coaster works:

The motion of the roller coaster contains many physical principles, which are intertwined by energy conservation, acceleration and force. At the beginning of the implementation, the small train of the roller coaster is pushed to the highest point by the thrust of a mechanical device. After the first descent, it was no longer powered by any device. In fact, from this moment on, the only 'engine' that drives it along the track will be gravitational heat energy, which is constituted by the continuous transformation process of converting gravitational heat energy into kinetic energy, and then converting kinetic energy into gravitational potential energy.

Power classification of roller coaster:

1. Chain lifter

A traditional lift is a long chain (or chains), like a bicycle chain, but much larger. It is installed under the track and extends up the lift. This chain is held in a loop with one gearing at the top and one at the bottom of the hill. The drive at the bottom of the hill is turned by a simple electric motor by turning the chain loop, making it move continuously towards the top of the hill like a long conveyor belt. The roller coaster uses a few chain lock springs and a strong hinge hook to hold the chain. When the train travels to the bottom of the hill, the lock springs can jam the links of the chain. Once the chain lock spring is hooked, the chain pulls the train towards the top of the mountain. At the highest point, the lock springs are released and the train starts to move down the hill.. the clack you hear from the chain is actually the sound of the anti-slip device that prevents the train from slipping back to the station if the motor fails cause an accident.

2. Catapult

In some newer roller coaster designs, the train is launched by means of a catapult launch. There are several ways to fire a catapult, but they do basically the same thing. Instead of dragging the train up the hill to accumulate potential energy, these systems allow the train to gain a lot of kinetic energy in a very short time at the start, allowing it to start running. Linear Induction Motor is one of the commonly used catapult systems. Linear induction motors use electromagnets to create a magnetic field above the track and below the train, and the two magnetic fields attract each other. Electric motors move the magnetic field above the track, pulling the train behind it along the track at extremely high speeds. The main advantages of such a system are its speed, efficiency, durability, accuracy and controllability, and the Hydralic Launching System appears in roller coasters produced by Intermin. This is a slider with a steel cable, driven by a flywheel driven by water pressure. When launching, the slider is stuck under the train, and the high-speed rotating flywheel quickly pulls the slider and rushes out together with the train. At the end of the launch section, the slider is decoupled from the train, and the train relies on the kinetic energy obtained to rush to a height of about 100 meters.

3. Friction Wheel

This roller coaster uses dozens of rotating wheels (Friction Wheel1) to propel the train up and down the elevated hill. The wheels are arranged in two adjacent rows along the track. They jam the bottom (or top) of the train in the middle, pushing the train forward. It is often used when climbing slopes are turning (because the chain cannot turn laterally on a horizontal plane) or to adjust the speed of the train to be equal to the speed of the chain before the chain lifter. And the Hulk roller coaster at Universal Orlando uses these wheels to accelerate the train out of the tunnel.
