Title:
VIBRATION MODE CALCULATION METHOD AND VIBRATION MODE CALCULATION DEVICE
Document Type and Number:
Japanese Patent JP2012088834
Kind Code:
A
Abstract:

To provide a vibration mode calculation method and a vibration mode calculation device capable of efficiently and accurately generating distribution of frequencies of natural vibration of tires and degree of vibration modes.

In a vibration mode calculation method, coordinates of a mode vector at each node of a tire model calculated in a Cartesian coordinate system is converted into coordinates in a local coordinate system, and analyzing the converted mode vector calculates distribution of a frequency included in vibration of the converted mode vector and degree of a vibration mode.
