Analysis of Amusement Ride Manufacturing Technology

Modern amusement ride manufacturing is a combination of precision machining, advanced material science, and intelligent control technology. From the thrilling tracks of roller coasters to the ornate decorations of carousel rides, each part relies on systematic processing techniques. This article will analyze core processes like cutting, welding, surface treatment, and inspection to reveal the technical logic behind amusement ride manufacturing.

Precision Cutting Technology: Millimeter-Level Art

Laser cutting and CNC cutting are two different processing techniques. While both are used for precise material cutting, they differ significantly in principles, equipment, applications, and characteristics.

Laser Cutting Technology for Amusement Rides

Laser Cutting

Uses a high-energy laser beam to melt, vaporize, or burn material. Auxiliary gas (like nitrogen or oxygen) blows away molten material to complete the cut. It is a thermal process known for high precision and quality.

CNC Machining for Precision Parts

CNC Cutting

A broad term for computer-controlled cutting methods, including plasma, flame, and water jet cutting. It can be thermal (plasma, flame) or cold (water jet) processing.

Comparison Between the Two Technologies

Laser cutting is a type of CNC cutting that offers high precision and quality. In contrast, CNC cutting covers various techniques and equipment. The best choice depends on material, thickness, precision needs, and budget.

Intelligent Welding Technology: Molecular-Level Fusion of Metals

1.MIG Welding (Metal Inert Gas Welding)

MIG welding uses a continuously fed metal electrode to form a weld pool under the protection of argon or mixed gases. The pulse function precisely controls the heat input to achieve efficient and stable metal connections.

MIG Welding Process Used in Amusement Rides
Technical Advantages

  • Welding Speed: 1.2-1.8m/min
  • Penetration Control: Adjustable range of 0.5-15mm
  • Applicable Materials: Carbon steel, stainless steel, aluminum alloy
Typical Applications:

  • Roller Coaster Track Welding: Uses ER70S-6 welding wire to ensure the roller coaster’s track connection strength
  • Rotating Platform Welding: Uses Ar+2%O₂ mixed gas protection to improve welding quality

2.Robotic Welding Systems

Robotic welding system uses automated robotic arms for precise welding, ensuring efficient and stable weld quality through control systems and sensors.

  • Swing Ride Welding: Improves welding precision to ensure safety

Composite Material Process: The Revolution of Lightweight

The "3 Mat 2 Cloth" technique is a composite material manufacturing process primarily used for producing high-performance fiberglass (FRP, Fiber Reinforced Plastic) or other composite products. By alternately layering multiple materials, this process enhances the strength, durability, and other performance characteristics of the product.

3 Mat 2 Cloth Technique for High-performance Fiberglass

Specific Process:

  • 3 Mat: Three layers of chopped strand mat (CSM) provide uniform strength and thickness
  • 2 Cloth: Two layers of woven roving offer higher strength and toughness

Process Steps:

Lay down a layer of chopped strand mat on the mold, then apply resin (such as unsaturated polyester resin).
Next, lay down a layer of woven roving and apply resin.
Repeat the above steps, alternating the "3 Mat 2 Cloth" sequence until the desired thickness and performance are achieved.
Finally, complete the product through curing and demolding.

Advantages:

  • High Strength: Multiple layers of materials combine to offer high mechanical strength and impact resistance
  • Lightweight: Fiberglass products are lighter than metals, ideal for applications requiring weight reduction
  • Corrosion Resistance: Fiberglass offers excellent corrosion resistance, suitable for harsh environments like chemical and marine industries
  • Flexible Design: Layer numbers and material combinations can be adjusted to meet different performance needs

Surface Treatment Technology: Invisible Protective Layer

Shot blasting is a surface treatment process that uses abrasive materials (such as steel shot, steel grit, glass beads) propelled at high speeds to clean the surface of workpieces by removing rust, oxide layers, old coatings, or other contaminants.

Shot Blasting Treatment for Amusement Rides

Working Principle

  • Shot Blasting Equipment: The shot blasting machine accelerates the abrasive materials through high-speed rotating impellers, projecting them onto the workpiece surface.
  • Abrasive Impact: The abrasives hit the workpiece surface at high speeds, removing rust, oxide layers, and other contaminants while creating a certain surface roughness.
  • Abrasive Recovery and Separation: Used abrasives are collected and separated by the recovery system for reuse.

Technical Advantages

  • Efficient Rust Removal: Quickly removes rust and contaminants from the surface.
  • Surface Roughness Control: Improves coating adhesion and enhances fatigue resistance.
  • Environmentally Friendly: Reusable abrasives reduce waste.

Specific Applications:

  • Pendulum Ride Steel Structure Rust Removal: Ensures cleanliness and coating adhesion on structural surfaces.
  • Rust Removal for Rotating Equipment Parts: Enhances fatigue resistance and extends the lifespan of parts.
  • Maintenance of Large Amusement Ride: Regular rust removal ensures safety and reliability of the equipment.

Non-Destructive Testing System: The Guardian of Quality

Magnetic Particle Testing (MT or MPI) is a non-destructive testing (NDT) method used to detect surface or near-surface defects in ferromagnetic materials (such as steel, iron, nickel, cobalt, and their alloys). It uses a magnetic field and magnetic particles to reveal cracks, pores, inclusions, and other defects in the material.

Magnetic Particle Inspection

Basic Principle:

  • Magnetization: Apply a magnetic field to the workpiece, creating magnetic lines of force inside it. If there are surface or near-surface defects, the magnetic lines will distort at the defect, forming a leakage field.
  • Apply Magnetic Particles: Spray magnetic particles (dry powder or suspension) onto the surface of the workpiece. The particles will be attracted to the leakage field, accumulating at the defect and forming visible magnetic indications.
  • Observation and Analysis: Observe the magnetic indications with the naked eye or auxiliary tools (such as UV lamps) to determine the location, shape, and size of the defects.

Technical Advantages:

  • Detects microcracks as small as 0.1mm
  • Testing speed of 3-5 minutes per part
  • Does not require complex equipment
  • Can be performed on-site

Typical Application Cases:

  • Full inspection of pirate ship ride track welds
  • Screening for surface fatigue cracks on the main shaft of large pendulum rides
  • Monthly inspection of critical welds on swing tower steel structures
  • Crack inspection around bolt holes on high-altitude equipment

Conclusion

Modern amusement ride manufacturing integrates various advanced technologies to ensure precise machining and strict quality control of each component. These technologies not only make the rides visually appealing and high-performing but also enable long-term stable operation, providing a safe and thrilling entertainment experience. In the future, these technologies will continue to evolve and improve, bringing more innovation and enhancements to the design and manufacturing of amusement rides.
