What Are The Differences in The Application of Aluminum Alloy Trusses in Different Types of Extreme Sports Events?

Functional Purposes

• Aerial Extreme Sports Events

• Wingsuit Flying: Aluminum alloy trusses are mainly used to construct the take-off platforms and safety protection facilities in the landing areas. The take-off platform needs to provide athletes with a stable departure position, and it must have sufficient strength and levelness to ensure that athletes can take off in the correct posture. The safety protection facilities in the landing area should be able to withstand a certain impact force to prevent athletes from deviating from the landing area and getting injured.

• Bungee Jumping: Aluminum alloy trusses are used to build tall jumping platforms. The jumping platform not only has to bear the weight of the athletes but also resist external forces such as wind loads. At the same time, it must have good structural stability to ensure the safety of athletes during the jumping and rebounding processes.

• Terrestrial Extreme Sports Events

• Skateboarding and BMX: In these events, aluminum alloy trusses are used to construct various obstacle facilities, jump platforms, and enclosure structures of the venue. The obstacle facilities and jump platforms need to have different slopes, curvatures, and heights to meet the needs of athletes to perform various difficult stunts. The enclosure structures should be able to prevent athletes and equipment from flying out of the venue, ensuring the safety of surrounding people and facilities.

• Mountain Biking: It is mainly used to build bridges, jump platforms, ramps on the track, as well as the audience stands. The track facilities need to be able to withstand the impact force when bicycles and athletes pass at high speed, and different lengths, slopes, and curvatures should be designed according to different terrains and competition requirements. The audience stands need to have good stability and sufficient load-bearing capacity to provide a safe and comfortable viewing environment for the audience.

• Parkour: It can be used to build various obstacles, platforms, and support structures of different heights and shapes, forming a complex and changeable parkour route. These facilities need to be convenient for athletes to climb, jump, and perform flips, and they have high requirements for the flexibility and variability of the structure.

• Aquatic Extreme Sports Events

• Surfing and Water Skiing: Aluminum alloy trusses can be used to build water platforms, start and finish line identification frames, etc. The water platforms need to have good waterproof and anti-corrosion properties, and they should be able to remain stable in a wet and fluctuating water surface environment, providing athletes with a place to get on and off the water and rest. The start and finish line identification frames need to be eye-catching and firm, and they should be able to withstand the impact of water flow and waves.

• Jet Skiing: It can be used to construct buoy brackets of the track, audience stands, etc. The buoy brackets need to have sufficient buoyancy and stability, and they should be able to maintain their positions accurately under the interference of water flow and the movement of boats. The audience stands need to consider factors such as waterproofing, anti-slip, and corrosion resistance to ensure the safety and viewing experience of the audience.

Design Requirements

• Load-Bearing Capacity

• Aerial Extreme Sports: Since athletes generate a large impact force when jumping off or leaping out from a high place, such as in bungee jumping and wingsuit flying, aluminum alloy trusses need to have extremely high load-bearing capacity and impact resistance. Usually, precise mechanical calculations and designs are required according to factors such as the athletes' weight and take-off height.

• Terrestrial Extreme Sports: Different terrestrial extreme sports have different requirements for load-bearing capacity. The obstacle facilities and jump platforms in skateboarding, BMX, and other events need to be able to withstand the dynamic loads generated by athletes and equipment during high-speed movement and stunt performance. The track facilities for mountain biking need to consider the weight of bicycles and athletes and the impact force during high-speed driving. Although the weight of a single athlete in parkour events is relatively small, the comprehensive load when multiple athletes use the facilities simultaneously needs to be considered.

• Aquatic Extreme Sports: In addition to bearing the weight of athletes and related equipment, it is also necessary to consider the buoyancy of water, the impact force of water flow, and the force of wind and waves. For example, water platforms and audience stands need to have sufficient buoyancy and stability to ensure safety.

• Structural Stability

• Aerial Extreme Sports: The structural stability of the take-off platform and jumping platform is of vital importance. Any slight shaking or deformation may affect the safety and performance of athletes. Usually, more robust connection methods and support structures are required, such as adding diagonal braces and strengthening node connections.

• Terrestrial Extreme Sports: The venue facilities need to remain stable under the repeated impacts and frictions of athletes. For the jump platforms and obstacle facilities in skateboarding, BMX, and other events, they need to ensure that they will not tilt or collapse under the action of forces in different directions. The bridges and jump platforms on the mountain biking track need to be able to withstand the vibrations and impact forces when vehicles pass. Parkour facilities need to remain stable during the rapid movement and action changes of athletes.

• Aquatic Extreme Sports: Due to the influence of water buoyancy, water flow, and wind waves, the requirements for the structural stability of aquatic facilities are even higher. Special foundation designs and fixing methods, such as driven foundations and anchor systems, need to be adopted to prevent the facilities from shifting or tilting.

Material Characteristics

• Aerial Extreme Sports: Usually, aluminum alloy trusses with higher strength and stiffness are required to ensure safety and stability in high-altitude environments. Higher-strength aluminum alloy materials, such as 6061-T6 or 7075-T6, may be selected, and the surface treatment of the materials also has higher requirements to improve corrosion resistance and weather resistance.

• Terrestrial Extreme Sports: In addition to strength and stability, the wear resistance and fatigue resistance of the materials also need to be considered, because there will be frequent contacts and frictions between athletes and equipment and the facilities. At the same time, according to different venue environments, such as indoor or outdoor, wet or dry, etc., appropriate surface treatment methods should be selected to extend the service life.

• Aquatic Extreme Sports: The requirements for the corrosion resistance of materials are extremely high. Generally, aluminum alloy materials with good seawater corrosion resistance are selected, and special anti-corrosion treatments, such as anodizing and coating anti-corrosion coatings, are carried out to prevent the materials from rusting and being damaged in a wet and corrosive environment.
