Designing Suspension Top Mount: Calculate Forces

In summary, the speaker is currently designing a new car suspension top mount for a university project and is using CAD for the design. They are struggling to find information on how to calculate the forces the mount will need to withstand, specifically the maximum lateral and longitudinal forces. They also mention that the weight of the car is 1060kg and the maximum loading is 1650kg. Another speaker adds that the vertical force should not exceed the weight of the entire car on one wheel.

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!
 

1. What is a suspension top mount?

A suspension top mount is a component of a vehicle's suspension system that connects the shock absorber to the vehicle's body or frame. It helps to absorb the impact of bumps and uneven road surfaces, providing a smoother and more comfortable ride.

2. How do you calculate the forces on a suspension top mount?

The forces on a suspension top mount can be calculated by using the equation F = ma, where F is the force, m is the mass of the vehicle, and a is the acceleration caused by the impact. Other factors such as shock absorber stiffness and damping can also affect the forces on the top mount.

3. What are the key design considerations for a suspension top mount?

The key design considerations for a suspension top mount include load capacity, durability, and ease of installation. The top mount should be able to handle the weight of the vehicle and any additional loads, withstand regular impacts from road conditions, and be designed for easy replacement or repair.

4. How does the design of a suspension top mount impact a vehicle's handling?

The design of a suspension top mount can impact a vehicle's handling by affecting the stiffness and damping of the suspension system. A well-designed top mount can provide better handling and stability, while a poorly designed one can lead to a bumpy and uncomfortable ride.

5. Are there any safety considerations when designing a suspension top mount?

Yes, safety should always be a top priority when designing a suspension top mount. The top mount must be able to withstand the forces and impacts of regular driving without failing. It should also be designed to minimize the risk of any potential hazards or failures that could affect the vehicle's stability and safety.
