Abstract:
Dynamic test and modal analysis on site for machine-foundation-subgrade interaction system were carried out. On this basis, its dynamic parameters were identified, and its working performance was evaluated. Through field research and synthesis analysis of testing data, vibration characteristics of interaction system were obtained, main causes of vibration fault were discussed. To take it further, authors concluded the diagnosis results and purposefully suggested some practical and feasible counter measures for reinforcement and rehabilitation. The analysis method can provide reference for dynamic parameter identification and fault diagnosis of machine-foundation-subgrade interaction system.
