SUMMARY

The discussion focuses on the analysis of compressive forces in a suspension system utilizing a bottle jack and a load cell. The user inquires whether the force measured by the load cell reflects the exact force applied by the bottle jack, considering the compression of the tyre. It is established that the forces will balance out under static load conditions, and the compression of the tyre behaves similarly to a spring, not diminishing the applied force.

PREREQUISITES
  • Understanding of load cells and their measurement capabilities
  • Basic knowledge of suspension systems and their components
  • Familiarity with static load principles in mechanical systems
  • Concept of force balance in mechanical systems
NEXT STEPS
  • Research the mathematical relationships governing force distribution in suspension systems
  • Explore the characteristics and applications of load cells in force measurement
  • Study the behavior of materials under compression, particularly rubber and tyre carcasses
  • Learn about static versus dynamic loading in mechanical engineering
USEFUL FOR

Mechanical engineers, automotive suspension designers, and anyone involved in the analysis and optimization of suspension systems.

I am doing some analysis on a suspension system. The suspension system is braced on a metal rig. Force is applied to it by manually pumping up a bottle jack. The ram of the jack pushes a compression plate onto the bottom of the tyre carcass.
In order to measure the vertical force input I have placed a load cell between the tyre carcass and the compression plate. Am I correct in thinking that the output from the load cell will not be the exact force I am applying with the bottle jack. Does the compression of the tyre use up some of the force exerted? Is there any mathematical relationship that can be applied to this scenario?
Any help would be greatly apreciated! :biggrin:

Nope, the forces will balance out as long as you're applying a static load.

Force will not be 'used up' by the compression of the tyre, - think of it as squashing a spring.
