| Abstract: | This paper introduces an improved method for thermo-modal test.By using vibration shaker tables to provide a driven-base excitation and laser vibrometer to make non-contact vibration measurement,the rudder had been developed thermo-modal test successfully.Variation characteristics of first bend and torsion frequency along with thermal load have been obtained.The technology has achieved good results and with great value. |
