Experimental Modal Analysis of Vehicle Body in White

摘要：

　　In order to know the vibration characteristics of the vehicle body in white, the experimental modal analysis was performed by using LMS modal equipment.The basic principle of experimental modal analysis was introduced.Then, the first ten order modes were obtained within 100 Hz.The front several main modes were analyzed.The test results fully show that the car body in white has excellent first order torsional, bending and overall vibrational characteristics.
