4. Understanding Key Suspension Geometry Parameters

Before diving into software, it’s crucial to understand the key parameters that define suspension geometry. These parameters influence handling, stability, and overall performance.

4.1. Camber

Camber refers to the angle of the wheel relative to the vertical axis, as viewed from the front or rear of the vehicle. Positive camber means the top of the wheel is tilted outwards, while negative camber means it’s tilted inwards.

• Effect on Handling:
  • Negative camber improves grip during cornering by keeping the tire flatter on the road.
  • Excessive negative camber can reduce straight-line grip and increase tire wear.
• Typical Values:
  • Street Cars: 0 to -1 degree
  • Race Cars: -2 to -5 degrees

4.2. Caster

Caster is the angle of the steering axis relative to the vertical axis, as viewed from the side of the vehicle. Positive caster means the steering axis is tilted rearwards, while negative caster means it’s tilted forwards.

• Effect on Handling:
  • Positive caster improves straight-line stability and steering feel.
  • It also increases camber gain during steering, enhancing grip in corners.
• Typical Values:
  • Street Cars: +2 to +5 degrees
  • Race Cars: +5 to +10 degrees

4.3. Toe

Toe refers to the angle of the wheels relative to the longitudinal axis of the vehicle, as viewed from above. Toe-in means the front of the wheels are pointing inwards, while toe-out means they are pointing outwards.

• Effect on Handling:
  • Toe-in improves straight-line stability but can reduce turn-in response.
  • Toe-out improves turn-in response but can make the car feel nervous at high speeds.
• Typical Values:
  • Street Cars: 0 to +0.2 degrees (toe-in)
  • Race Cars: -0.2 to +0.2 degrees (toe-in or toe-out)

4.4. Roll Center

The roll center is the point around which the vehicle rolls during cornering. It’s determined by the suspension geometry and affects the amount of body roll and weight transfer.

• Effect on Handling:
  • A higher roll center generally reduces body roll but can increase jacking forces.
  • A lower roll center generally increases body roll but can improve grip.
• Optimization:
  • Roll center height is often adjusted to balance body roll and grip.

4.5. Instantaneous Center (IC)

The instantaneous center is the point about which the suspension arm rotates at a given instant. It’s used to determine the roll center and analyze suspension kinematics.

• Effect on Handling:
  • The location of the IC influences the suspension’s response to bumps and cornering forces.
  • Understanding IC migration is crucial for optimizing suspension performance.

4.6. Anti-Squat and Anti-Dive

Anti-squat and anti-dive refer to the suspension’s resistance to squatting under acceleration and diving under braking. They are influenced by the suspension geometry and affect weight transfer and traction.

• Effect on Handling:
  • High anti-squat can improve traction during acceleration but can also cause wheel hop.
  • High anti-dive can reduce front-end dive under braking but can also make the car feel unstable.
• Optimization:
  • Anti-squat and anti-dive are often adjusted to balance traction and stability.

5. How to Use Race Car Suspension Geometry Software

Using race car suspension geometry software effectively requires a systematic approach. Here’s a step-by-step guide:

1. Define Your Goals: Determine what you want to achieve with your suspension setup. Are you looking for improved cornering grip, better straight-line stability, or a more comfortable ride?

3. Create a Model: Input the data into the software to create a virtual model of your suspension system.
4. Simulate and Analyze: Run simulations to analyze the suspension’s behavior under various conditions, such as cornering, braking, and acceleration.
5. Adjust Parameters: Experiment with different suspension parameters, such as camber, caster, and toe, to see how they affect performance.
6. Validate Results: Compare the simulation results with real-world testing to validate the accuracy of the model.
7. Iterate and Refine: Continuously iterate and refine your suspension setup based on the simulation results and real-world testing.

6. Tips for Optimizing Your Suspension Setup

Optimizing your suspension setup is a complex process that requires a deep understanding of vehicle dynamics. Here are some tips to help you get started:

• Start with a Baseline: Begin with a known good suspension setup and make small changes one at a time.

• Seek Expert Advice: Consult with experienced race car engineers or suspension specialists for guidance.

7. Advanced Suspension Concepts

Once you have a solid understanding of the basics, you can explore more advanced suspension concepts:

• Roll Steer: Roll steer refers to the change in toe angle as the suspension rolls. It can be used to fine-tune the handling balance of the car.
• Bump Steer: Bump steer refers to the change in toe angle as the suspension moves up and down. It can cause instability and should be minimized.
• Heave Springs: Heave springs are used to control the vertical movement of the car’s body. They can improve stability and reduce body roll.
• Third Springs: Third springs are used to control the pitch and roll of the car’s body independently. They can provide a significant performance advantage.
• Inertia Dampers: Inertia dampers are used to control the high-frequency vibrations of the suspension. They can improve ride quality and handling.
