1. What is Side View Swing Arm Height?

Side View Swing Arm Height is the vertical distance from the wheel center to the upper pivot point of the swing arm in an independent suspension system. It plays a crucial role in determining the anti-lift characteristics of a vehicle's suspension.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ SVSAh = \frac{\%ALr}{(\%Br) \times \left(\frac{1}{SVSAl}\right) \div \left(\frac{h}{b}\right)} \]

Where:

\( SVSAh \) — Side View Swing Arm Height (m)
\( \%ALr \) — Percentage Anti Lift (%)
\( \%Br \) — Percentage Rear Braking (%)
\( SVSAl \) — Side View Swing Arm Length (m)
\( h \) — Height of CG above Road (m)
\( b \) — Wheelbase of Vehicle (m)

Explanation: This formula calculates the optimal swing arm height based on various suspension parameters to achieve the desired anti-lift percentage during braking.

3. Importance of SVSAh Calculation

Details: Accurate calculation of Side View Swing Arm Height is essential for proper suspension tuning, ensuring optimal vehicle stability, control, and braking performance in independent suspension systems.

4. Using the Calculator

Tips: Enter all values in the specified units. Percentage values should be entered as numbers (e.g., 60.88889 for 60.88889%). All input values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Why is Side View Swing Arm Height important in suspension design?
A: SVSAh directly affects the anti-lift characteristics during braking, influencing vehicle pitch control and overall stability.

Q2: How does Percentage Rear Braking affect the calculation?
A: Percentage Rear Braking determines the proportion of braking force applied to the rear wheels, which directly impacts the required swing arm height for optimal anti-lift performance.

Q3: What is the typical range for Side View Swing Arm Height?
A: SVSAh values vary depending on vehicle design, but typically range from 0.1 to 0.5 meters for most passenger vehicles.

Q4: How does Center of Gravity height affect the calculation?
A: Higher center of gravity increases the leverage effect during braking, requiring different swing arm height to achieve the same anti-lift percentage.

Q5: Can this calculator be used for both front and rear suspension?
A: This specific formula is designed for calculating swing arm height in relation to anti-lift characteristics, which is typically more relevant for rear suspension systems.
