Introduction about Dual Axis Steering (DAS) System of BMW F1 car:-

The dual-axis steering system (DAS) of the BMW F1 car is a unique and innovative technology that was introduced during the 2020 F1 season. This system allows the driver to adjust the toe angle of the front wheels while driving, which can help to improve tire wear and increase straight-line speed.

The construction of the DAS system involves several key components. At the heart of the system is a steering column that has two separate modes of operation. In the first mode, the steering wheel functions like a traditional F1 steering wheel, controlling the angle of the front wheels through a conventional steering rack and pinion.

In the second mode, the driver can pull the steering wheel towards them, which activates the DAS system. This causes the steering column to move inwards, which in turn causes the tie rods on the front suspension to move, adjusting the toe angle of the front wheels. This can be used to increase or decrease the toe angle, depending on the needs of the driver and the track conditions.

The DAS system of the BMW F1 car is hydraulic, with a hydraulic cylinder mounted inside the chassis that is used to control the movement of the steering column. The system is controlled by a series of sensors and a control unit, which are integrated into the car's electronics system.

Overall, the construction of the DAS system of the BMW F1 car involves a unique and innovative design that allows the driver to adjust the toe angle of the front wheels while driving. This can help to improve tire wear and increase straight-line speed, providing a significant advantage on the track.

Advantage of Dual Axis Steering (DAS) System BMW F1 Car:-

The dual-axis steering (DAS) system of the BMW F1 car provides several advantages on the track:

1.    Improved tire wear: By allowing the driver to adjust the toe angle of the front wheels while driving, the DAS system can help to reduce tire wear, especially on high-speed tracks where the tires are subjected to high loads.

2.    Increased straight-line speed: By adjusting the toe angle of the front wheels during straights, the DAS system can reduce drag and increase top speed, providing a significant advantage on long straights.

3.    Better handling: By adjusting the toe angle of the front wheels during corners, the DAS system can improve handling and reduce understeer or oversteer, allowing the driver to take corners faster and more consistently.

Dis-advantage of Dual Axis Steering (DAS) System BMW F1 Car:-

There are some potential disadvantages associated with the dual-axis steering (DAS) system of the BMW F1 car, including:

1.    Complexity: The DAS system is a complex and sophisticated technology that requires a high level of expertise and maintenance. This can add to the cost and time required for the team to maintain and operate the system.

2.    Weight: The DAS system adds weight to the car, which can reduce acceleration and cornering performance, especially in tight corners where the car's weight distribution is critical.

3.    Regulatory uncertainty: The DAS system is a new technology that has raised questions about its compliance with FIA regulations. While the system was approved for use during the 2020 F1 season, there is still some uncertainty about whether it will be allowed in future seasons.

4.    Driver distraction: The use of the DAS system requires the driver to pull the steering wheel towards them while driving, which could potentially be a distraction and affect their concentration on the track.

5.    Overall, the potential disadvantages of the DAS system of the BMW F1 car are relatively minor compared to its potential advantages, but they should still be considered when evaluating the system's overall performance and value.
