Title:
DISK BRAKE VIBRATION ESTIMATION METHOD AND DISK BRAKE VIBRATION ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/084363
Kind Code:
A1
Abstract:
A disk brake vibration estimation method for estimating vibration at the time of contact between a disk rotor of a disk brake that generates braking force and a pad by bringing the pad into contact with the rotating disk rotor comprises: acquiring input physical quantities that are physical quantities relating to the disk rotor and the pad (step ST1); estimating the vibration of the disk brake on the basis of the acquired input physical quantities, load variations between the disk rotor and the pad and between the pad and a fluid pressure receiving part, a friction variation between the disk rotor and the pad, and in-plane direction vibratory force generated in the circumferential direction of the disk rotor (step ST2); and displaying the result of the estimation (step ST3). The vibration of the disk brake in an in-plane direction can be estimated.
