Non-probabilistic Analysis Of Mechanism Reliability On Satellite Antenna Deployment Mechanism

The first part of the paper deals with the theory on kinematical reliability of mechanism. To the object of representative kinematical structure and mechanism, research the invalidate mode of kinematical structure and mechanism caused by many kinds of invalidate factor. Then sum up the reliability analysis method of mechanism kinematical precision and dynamical precision, build up correlate math function and mode. Afterward analyze their reliability by using non- probabilistic method, get their non- probabilistic reliability target function. Design correspond program and apply to math example successful. The second part of the paper discussed the model on reliability and the analyzing method of satellite antenna deployment mechanism. The FTA is applied to the model. Then have reliability analyzed and engineering computed to key component of mechanism by non- probabilistic method. By analyzing the bottom event, the system non- probabilistic reliability index is predicted. On the basis of working condition of components, the relevant reliability of components is allocated to with the help of reliability allocation program. At last, make a summary of non-probabilistic method used in satellite antenna deployment mechanism reliability analysis.
