Designing Suspension Top Mount: Calculate Forces

Click For Summary
SUMMARY

The discussion focuses on designing an upgraded car suspension top mount for a university project, specifically for a front suspension McPherson strut. Key parameters include a car weight of 1060 kg and a maximum loading capacity of 1650 kg. The maximum lateral and longitudinal forces are determined by the tire's maximum friction force in any direction. It is emphasized that exceeding the car's weight on a single wheel during weight transfer can lead to significant issues.

PREREQUISITES
  • Understanding of McPherson strut suspension systems
  • Familiarity with CAD software for design
  • Knowledge of vehicle dynamics and weight transfer
  • Basic principles of force calculation in mechanical engineering
NEXT STEPS
  • Research the calculation of lateral and longitudinal forces in vehicle dynamics
  • Explore CAD software capabilities for simulating suspension components
  • Learn about tire friction coefficients and their impact on vehicle performance
  • Investigate weight transfer effects during acceleration and braking
USEFUL FOR

This discussion is beneficial for automotive engineering students, suspension system designers, and mechanical engineers focused on vehicle dynamics and performance optimization.

I am currently designing a upgraded car suspension top mount for my university project. I am designing it in CAD and need to test it against the forces it will need to withstand however i can find no information to calculate such forces. It would be the front suspension mcfersion strut

Any assistance would be greatly appreciated

weight of car 1060kg
max loading 1650kg

Maximum lateral & longitudinal forces: It corresponds to the tire maximum friction force (In any direction)

As for the vertical force, if you get more than the entire weight of the car on one wheel (with the weight transfer), you are probably in big trouble!
