Roller Coaster Wheel Assembly
Today's modern roller coasters, both wooden and steel, have the same basic design of wheel assembly. Each wheel assembly has three wheels: underfriction, or up-stop, wheels; tractor, or running, wheels; and side friction wheels. All of these help the train move safely and smoothly. All modern roller coasters have up-stop wheels that hug the bottom of the rail. As their name implies, they prevent the train from coming up off the track. Side friction wheels hug the sides of the rail, either the outside or inside, depending on the track manufacturer. These wheels help the train stay in the center of the two rails to keep the train from derailing. The last wheel set are called tractor wheels, or running wheels. Tractor wheels have a simple but important purpose. These wheels bear the weight of the train on the track, keeping the train running on the track. Tractor wheels may lift off the track when the vertical g-force is zero 0 (zero) is a number representing an empty quan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Underfriction
On a roller coaster train In rail transport, a train (from Old French , from Latin , "to pull, to draw") is a series of connected vehicles that run along a railway track and transport people or freight. Trains are typically pulled or pushed by locomotives (often ..., the underfriction, up-lift, or up-stop wheels are a device to keep the train from jumping off the track under intense movement. The design was patented in 1919 by John A. Miller. References Roller coaster technology {{tech-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
G-force
The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g (not gram in mass measurement) equal to the conventional value of gravitational acceleration on Earth, ''g'', of about . Since g-forces indirectly produce weight, any g-force can be described as a "weight per unit mass" (see the synonym specific weight). When the g-force is produced by the surface of one object being pushed by the surface of another object, the reaction force to this push produces an equal and opposite weight for every unit of each object's mass. The types of forces involved are transmitted through objects by interior mechanical stresses. Gravitational acceleration (except certain electromagnetic force influences) is the cause of an object's acceleration in relation to free fall. The g-force experienced by an object is due to the vector sum of all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weightlessness
Weightlessness is the complete or near-complete absence of the sensation of weight. It is also termed zero gravity, zero G-force, or zero-G. Weight is a measurement of the force on an object at rest in a relatively strong gravitational field (such as on the surface of the Earth). These weight-sensations originate from contact with supporting floors, seats, beds, scales, and the like. A sensation of weight is also produced, even when the gravitational field is zero, when contact forces act upon and overcome a body's inertia by mechanical, non-gravitational forces- such as in a centrifuge, a rotating space station, or within an accelerating vehicle. When the gravitational field is non-uniform, a body in free fall experiences tidal effects and is not stress-free. Near a black hole, such tidal effects can be very strong. In the case of the Earth, the effects are minor, especially on objects of relatively small dimensions (such as the human body or a spacecraft) and the overa ...

Bolliger & Mabillard
Bolliger & Mabillard, officially Bolliger & Mabillard Consulting Engineers, Inc. and often abbreviated B&M, is a roller coaster design consultancy based in Monthey, Switzerland. The company was founded in 1988 by Walter Bolliger and Claude Mabillard, both of whom had worked for Giovanola. B&M has pioneered several new ride technologies, most notably the inverted roller coaster and the box-section track. In 2016, the company completed its 100th roller coaster. B&M produces nine types of coaster models: Stand-Up Coaster, Inverted Coaster, Floorless Coaster, Flying Coaster, Hyper Coaster, Dive Coaster, Sitting Coaster, Wing Coaster and Family Coaster. Though B&M has not used the term, the company has also manufactured three giga coasters. History Roots Walter Bolliger and Claude Mabillard started working for Giovanola, a manufacturing company who supplied rides to Intamin, in the 1970s. During their time at Giovanola, they helped design the company's first stand-up roller c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arrow Dynamics
Arrow Dynamics was an American manufacturing and engineering company that specialized in designing and building amusement park rides, especially roller coasters. Based in Clearfield, Utah, the company was the successor to Arrow Development (1946–1981) and Arrow Huss (1981–1986), which were responsible for several influential advancements in the amusement and theme park industries. Among the most significant was tubular steel track, which provided a smoother ride than the railroad style rails commonly used prior to the 1960s on wooden roller coasters. The Matterhorn Bobsleds at Disneyland, built in 1959, was Arrow's first roller coaster project. In 1975, Arrow Development introduced the first corkscrew style track Corkscrew, at Knott's Berry Farm that sent riders through a series of corkscrews. Arrow created several other "firsts" over the years, introducing the first suspended roller coaster in almost a century, The Bat, in 1981, and the world's first "hypercoaster", Magnu ...
