PROBLEM TO BE SOLVED: To provide a disc brake vibration estimation device which can accurately estimate the vibration of a disc brake in an in-plane direction.SOLUTION: A disc brake vibration estimation device 1 has an in-plane spring value calculation part 31 which calculates an in-plane spring value for deciding an in-plane directional excitation force which is generated in the in-plane direction of a disc rotor 104, and a vibration estimation part 32 which estimates the vibration of a disc brake 100 in the in-plane direction on the basis of the in-plane spring value. The in-plane spring value calculation part 31 calculates an actual in-plane spring value on condition that a value obtained by dividing the moment which is generated at a node constituting a contact face at which pad models 102', 103' contact with a disc rotor model 104' by an entire of the contact face is balanced with the actual moment of an entire of pads which is measured in a state that the pads 102, 103 contact with the rotating disc rotor 104. |
