Modal Analysis and Fault Diagnosis of Dynamic Machine Foundation under Ambient Excitation
This paper introduces the modal parameter identification method of a reinforced concrete block foundation under ambient excitation. On this basis, the dynamic characteristics of a stone cutting machine foundation are obtained by modal test under different operating conditions, and test results reveal that the main cause of abnormal vibration lies in lower dynamic stiffness of the whole structure. With the comparison of dynamic response between pre-reinforcement and post-reinforcement, reinforcement effects of high pressure grouting technique and pre-stressed bolt applied to restrain foundation vibration are verified effectively.
