1. What is the Height of Centre of Gravity Calculation?

The Height of Centre of Gravity from Road Surface calculation determines the vertical distance from the road surface to the vehicle's center of gravity using percentage anti-dive characteristics and suspension geometry parameters.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ h = \frac{(\%Bf) \times (SVSAh/SVSAl) \times b}{\%ADf} \]

Where:

\( h \) — Height of CG above Road (m)
\( \%Bf \) — Percentage Front Braking (%)
\( SVSAh \) — Side View Swing Arm Height (m)
\( SVSAl \) — Side View Swing Arm Length (m)
\( b \) — Wheelbase of Vehicle (m)
\( \%ADf \) — Percentage Anti Dive Front (%)

Explanation: This formula calculates the center of gravity height based on the vehicle's suspension geometry and braking characteristics.

3. Importance of CG Height Calculation

Details: Accurate CG height calculation is crucial for vehicle stability analysis, suspension design, and predicting vehicle behavior during braking and cornering maneuvers.

4. Using the Calculator

Tips: Enter all values in appropriate units. Percentage values should be entered as numbers (e.g., 60 for 60%). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is CG height important in vehicle dynamics?
A: CG height affects vehicle stability, roll characteristics, weight transfer during acceleration/braking, and overall handling performance.

Q2: What is percentage anti-dive?
A: Percentage anti-dive describes how much the suspension resists diving during braking. Higher values indicate more resistance to nose dive.

Q3: How does swing arm geometry affect CG calculation?
A: The swing arm geometry (height and length) determines the instant center location, which influences how forces are transmitted through the suspension.

Q4: What are typical CG height values for different vehicles?
A: Sports cars typically have lower CG heights (0.4-0.5m), sedans (0.5-0.6m), SUVs (0.6-0.8m), and trucks can have even higher CG heights.

Q5: Can this calculation be used for all suspension types?
A: This specific formula is designed for independent suspension systems with swing arm geometry. Different formulas may be needed for other suspension types.
