Understanding the Basics of Tube Exoskeletons for Cars

A tube exoskeleton, also known as a space frame or tubular frame, is a lightweight and highly rigid structural system used in the construction of cars, especially racing cars and high-performance vehicles. It consists of a network of interconnected steel or aluminum tubes that form the main structural framework of the vehicle.

Tube exoskeletons offer several advantages compared to traditional monocoque or unibody designs. They provide exceptional strength and stiffness while minimizing weight, making them ideal for applications where weight reduction and structural integrity are paramount. Their modular design allows for easy customization and repair, and they can be easily modified to accommodate different vehicle configurations and powertrain layouts.

Tube exoskeletons are commonly constructed using precision-welded or seamless tubing, which is arranged in a triangulated structure to maximize strength and load distribution. The tubes are carefully placed to resist bending and torsion, creating a highly durable and responsive framework. The resulting structure is lightweight yet capable of withstanding significant forces, making it suitable for high-performance driving and racing applications.

Materials Used in Tube Exoskeletons

Steel Strong and durable, but heavier than aluminum
Aluminum Lightweight and strong, but more expensive than steel
Titanium Extremely strong and lightweight, but very expensive

Designing the Tube Exoskeleton Frame

The tube exoskeleton frame is a critical component of a tube exoskeleton for a car, providing both structural support and protection to the vehicle. To design a tube exoskeleton frame that meets the specific requirements of a particular vehicle, a number of factors must be considered, including:

Material Selection

The choice of material for the tube exoskeleton frame will depend on the intended use of the vehicle. For vehicles that will be used in high-speed or off-road applications, a strong and lightweight material such as titanium or carbon fiber may be the best choice. For vehicles that will be used in more everyday applications, a less expensive material such as steel or aluminum may be sufficient.

Tube Diameter and Thickness

The diameter and thickness of the tubes used to construct the exoskeleton frame will also affect the strength and weight of the structure. Larger diameter tubes will be stronger, but will also be heavier. Thicker tubes will also be stronger, but will also be more expensive to produce.

Tube Layout

The layout of the tubes in the exoskeleton frame will be determined by the specific geometry of the vehicle. The tubes should be arranged in a way that provides maximum strength and protection, while also minimizing the weight of the structure. The tubes should also be spaced evenly to prevent any one tube from carrying too much load.

Factor Considerations
Material Selection Intended use, strength, weight
Tube Diameter and Thickness Strength, weight, cost
Tube Layout Vehicle geometry, strength, protection, weight

Fabricating the Tube Exoskeleton Components

The first step in fabricating the tube exoskeleton components is to cut the tubes to the desired length. This can be done using a pipe cutter or a hacksaw.

Once the tubes are cut to length, they need to be bent into the desired shape. This can be done using a tube bender or a vice and a hammer. It is important to be careful when bending the tubes, as they can easily be damaged if they are bent too far.

After the tubes have been bent into the desired shape, they need to be welded together. This can be done using a TIG welder or a MIG welder. It is important to use a strong weld, as the exoskeleton will need to be able to withstand a lot of force.

Once the tubes have been welded together, the exoskeleton is complete. It can now be attached to the car.

Assembling the Exoskeleton

Once the exoskeleton components have been fabricated, they need to be assembled. This can be done by welding the components together or by bolting them together. It is important to ensure that the exoskeleton is assembled correctly, as it will need to be able to withstand a lot of force.

Once the exoskeleton is assembled, it can be attached to the car. This can be done by welding the exoskeleton to the car’s frame or by bolting it to the car’s body.

Welding Bolting
More permanent More easily disassembled
Requires specialized equipment Can be done with basic tools
Stronger Weaker

Welding and Assembly of the Tube Structure

Once the tubes have been cut and bent to the desired shape, they need to be welded together to form a rigid structure. This is a critical step, as the strength and durability of the exoskeleton will depend on the quality of the welds. It is important to use a high-quality welding machine and follow the manufacturer’s instructions carefully. The welding process should be done in a well-ventilated area, and protective gear should be worn to avoid exposure to fumes.

Tube Preparation

Before welding, the tubes need to be prepared by cleaning the ends to remove any dirt or debris. This can be done with a wire brush or a grinding wheel. The ends of the tubes should also be chamfered, which means that they should be beveled at a 45-degree angle. This will help to create a stronger weld.

Welding Techniques

There are a variety of welding techniques that can be used to weld steel tubes. The most common method is TIG (Tungsten Inert Gas) welding, which uses a tungsten electrode to create an arc between the electrode and the metal. Other methods include MIG (Metal Inert Gas) welding and stick welding.

Welding Sequence

The order in which the tubes are welded together is important. It is best to start by welding the main structural members of the exoskeleton, such as the frame and the supports. Once these are in place, the smaller tubes can be welded into place.

Post-Weld Inspection

Once the welding is complete, it is important to inspect the welds for any defects. This can be done with a visual inspection, or with a non-destructive testing method such as ultrasonic testing or radiography.
