Car Body Roll Test
What is Car Body Roll?
Car body roll is a measure of how much a car’s body leans to the side when it turns. It is caused by centrifugal force, which is the outward force that acts on an object moving in a circular path.
Body roll can be a problem because it can make the car feel unstable and can lead to loss of control. It can also be uncomfortable for passengers.
How is Car Body Roll Measured?
Body roll is measured in degrees. The higher the number, the more the car leans to the side.
There are two main ways to measure body roll:
- Static body roll: This is measured by parking the car on a flat surface and then turning the steering wheel to full lock. The angle of the car’s body is then measured.
- Dynamic body roll: This is measured by driving the car around a corner at a certain speed. The angle of the car’s body is then measured as it goes through the corner.
Factors that Affect Car Body Roll
There are a number of factors that can affect car body roll, including:
- Suspension: The suspension system is responsible for absorbing bumps and keeping the car’s tires on the ground. A stiffer suspension will reduce body roll, while a softer suspension will increase it.
- Weight distribution: The weight distribution of a car can also affect body roll. A car with a more balanced weight distribution will have less body roll than a car with a more uneven weight distribution.
- Tire size and type: The size and type of tires can also affect body roll. Wider tires will provide more grip, which will reduce body roll. Tires with a stiffer sidewall will also reduce body roll.
How to Reduce Car Body Roll
There are a number of ways to reduce car body roll, including:
- Upgrade the suspension: Installing a stiffer suspension system will reduce body roll. However, it is important to note that a stiffer suspension can also make the ride more uncomfortable.
- Improve the weight distribution: Adding weight to the rear of the car can help to improve weight distribution and reduce body roll. This can be done by adding a rear spoiler or by installing a heavier rear axle.
- Install wider tires: Wider tires will provide more grip, which will reduce body roll. However, it is important to note that wider tires can also be more expensive.
- Use tires with a stiffer sidewall: Tires with a stiffer sidewall will reduce body roll. However, it is important to note that stiffer sidewalls can also make the ride more uncomfortable.
Conclusion
Car body roll is a measure of how much a car’s body leans to the side when it turns. It can be caused by a number of factors, including suspension, weight distribution, and tire size and type. There are a number of ways to reduce body roll, including upgrading the suspension, improving the weight distribution, installing wider tires, and using tires with a stiffer sidewall.
