Modeling Hydraulic Brake Behavior

Click For Summary
SUMMARY

The discussion focuses on modeling the behavior of hydraulic brakes, specifically the relationship between the deformation of a steel leaf and the resulting friction force that generates braking torque. Key factors include the coefficient of friction between the materials in contact, the radius of the rotating disk, and the pressure applied to the leaf. The user seeks to establish a model that links these variables to accurately calculate braking torque and understand the activation mechanism of the brake system.

PREREQUISITES
  • Understanding of friction coefficients in material science
  • Knowledge of torque calculations in mechanical systems
  • Familiarity with hydraulic systems and their components
  • Basic principles of rotational dynamics
NEXT STEPS
  • Research methods for calculating the coefficient of friction between different materials
  • Study torque calculation formulas and their applications in braking systems
  • Explore the mechanics of hydraulic brake systems and their activation processes
  • Investigate the effects of rotational speed on braking performance
USEFUL FOR

Mechanical engineers, automotive engineers, and anyone involved in the design and analysis of braking systems will benefit from this discussion.

Relation between deformed foil and friction force
Summary: Relation between deformed foil and friction force

Good morning everyone,
i have a small leaf or steel that is bent from one side by a Pressure of many bars.
in front of the leaf there's a rotating disk, separated by the leaf by a small gap.
this leaf, as it deforms, wins the gaps and touches the disk, causing a breaking torque.

I wish to have a first step model in order to study this system. I don't know how to link the pressure with the torque i get.
i have drawn up a scheme as an attachment

You need to find the coefficient of friction between the two materials that are touching and the radius of the rotating disk to calculate the braking torque. How is the brake activated and how hard is it being pressed against the disk? Is it metal against metal? Are you bending that tab toward the disk? Are you looking for application force or braking torque, or both? How fast is the disk rotating?
