Title:
METHOD OF MEASURING EXCITATION FORCE OF VIBRATION GENERATING BODY
Document Type and Number:
Japanese Patent JP3649098
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To accurately measure excitation force even when an oscillator and a sensor are not attached onto a measured portion.
SOLUTION: A vibration generating body 1 is held while surrounded with a measuring jig 8, vibration is applied to the body 1 from a prescribed direction with known excitation force through the jig 8, physical quantities as to the vibration are measured in plural positions on the jig symmetrical on a measured point in the body 1, a transfer function of a vibration system including the jig 8 is found based on a measured result therein and the known excitation force, the body 1 is operated and physical quantities as to the vibration are measured in the plural positions, and the excitation force by the body 1 is found based on a measured result therein and the transfer function.
