1. What is Tyre Vertical Rate?

Tyre Vertical Rate is the spring rate controlled by the tyre compound, sidewall stiffness and operating pressure. It represents the vertical force acting on the tire per unit vertical displacement.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( K_t \) — Tyre Vertical Rate (N/m)
• \( K_w \) — Wheel Centre Rate (N/m)
• \( K_r \) — Ride Rate (N/m)

Explanation: This formula calculates the tyre vertical rate based on the relationship between wheel centre rate and ride rate in a vehicle suspension system.

3. Importance of Tyre Vertical Rate Calculation

Details: Accurate calculation of tyre vertical rate is crucial for vehicle suspension design, ride comfort analysis, and overall vehicle dynamics performance.

4. Using the Calculator

Tips: Enter Wheel Centre Rate and Ride Rate in N/m. Both values must be positive, and Wheel Centre Rate must be greater than Ride Rate for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What factors affect Tyre Vertical Rate?
A: Tyre compound stiffness, sidewall design, inflation pressure, and operating temperature all influence the tyre vertical rate.

Q2: How does Tyre Vertical Rate affect vehicle performance?
A: It affects ride comfort, handling characteristics, and the overall suspension system's response to road irregularities.

Q3: What are typical values for Tyre Vertical Rate?
A: Values vary significantly depending on tyre type and size, but typically range from 100-400 N/mm for passenger vehicles.

Q4: How is this different from overall suspension rate?
A: Tyre vertical rate is just one component of the overall suspension system, which also includes spring rates and damper characteristics.

Q5: Can this formula be used for all types of vehicles?
A: While the fundamental relationship holds, specific applications may require adjustments for different vehicle types and suspension configurations.
