Suspension Calculator is an assorted collection of vehicle dynamics mathematical models that enable calculation of static and dynamic properties of a vehicle, thereby furnishing data that is required for the development of a vehicle’s suspension system.

The application offers accurate and efficient analysis tools for scrutinizing vehicle characteristics of race cars, passenger vehicles and light-duty trucks. Furthermore, the application incorporates calculators that facilitate mathematical iterations for designing spring and damper based on user targets and system variables.

The mathematical models integrated into the application are listed below:

ANALYSIS OF VEHICLE CHARACTERISTICS

1. CoG Location
Horizontal location of CoG
Vertical location of CoG
Location of CoG of sprung mass

2. Load Transfer
Longitudinal load transfer
Later load transfer
Wheel loads due to kerb strike
Wheel loads due to aerodynamic forces
Wheel loads due to banking
Wheel loads due to gradient

3. Ride & Roll Behaviour
Ride rate of a vehicle in quarter car model
Roll stiffness of a vehicle
Roll gradient of a vehicle
• Anti-roll bar requirements of a vehicle

4. Pitching Behaviour
Pitch & Bounce frequencies of a vehicle
• Anti-dive characteristics of a vehicle
• Anti-squat characteristics of a vehicle
