Abstract:The experimental modal analysis of the selected self-propelled gun was completed with operational modal analysis experimental technique;the modal frequencies distribution and modal modes were obtained;the analyzed result by the proposed method was compared with that by the traditional one.The compared result shows that obtained result by the proposed method is in agreement with that by the traditional method.
Keywords:mechanics  self-propelled gun  operational modal  experiment  environment excitation
