Fault analysis and diagnosis for dyspneaing vibration of launching tower's pendulum system

The fault diagnosis for the overbalanced movement (dyspneaing vibration) phenomena of launching tower's pendulum system is researched. Firstly, an equivalent dynamic model is developed. Quasi-static method is used in the dynamic analysis of the model. The dynamic characteristic is researched based on the dynamic equation coming out of the dynamic analysis. Considering the dynamic characteristic, the test data is used for research and verification of the fault reason of the dyspneaing vibration. Finally, the resolution is given.
