Interface pressure distributions through structural modifications
Due to the friction forces acting at the rotor and pads interface, the pressure distribution at the interface is asymmetric in a disc brake system of normal floatingtype caliper design. The asymmetry and the high unevenness of the interface pressure distribution cause uneven wear and shorten li...

| description | Due to the friction forces acting at the rotor and pads
interface, the pressure distribution at the interface is
asymmetric in a disc brake system of normal floatingtype
caliper design. The asymmetry and the high
unevenness of the interface pressure distribution cause
uneven wear and shorten life of pads. It has been
speculated that these undesirable features promote disc
brake squeal.
This paper investigates the contact (interface) pressure
distributions at the rotor and piston-pad interface in
response to several ideas of simulated structural
(geometric or material) modifications. These
modifications are made on the pads and/or at the
interface between the piston and the back plate or at the
pad guide. A detailed finite element model is constructed
taking into account all significant contact interfaces
between disc brake components. Sliding frictional
contact is analyzed to obtain the interface pressure
distributions. A plausible modification is identified which
offers improved interface pressure distributions against
wear. This work may also help create a good design of
disc brakes for improved noise performance as well. |
