| titleOfInvention | A kind of ion thruster System in Small Sample Situation reliability estimation method based on performance degradation |
| abstract | A kind of ion thruster System in Small Sample Situation reliability estimation method based on performance degradation, includes the following steps：One：Design feature and critical failure pattern to ion thruster are analyzed, and the critical performance parameters for influencing its service life are chosen；Two：According to the deterioration laws of critical performance parameters y at any time, ion thruster System in Small Sample Situation Performance Degradation Model is established；Three：Determine ion thruster mean time to failure, MTTF t MTTF With Reliability Function R (t)；Four：To i-th ion thruster, it is recorded in time t ij When test performance degradation values y ij , i=1,2 ..., m, j=1,2 ..., n i , m is the ion thruster number of units of input experiment, n i For the total degree of i-th ion thruster performance test；Five：Estimate the unknown parameter in Performance Degradation Model；Six：System in Small Sample Situation reliability assessment is carried out to ion thruster using Reliability Function.The present invention develops and uses longitudinal information between different moments performance test data, and information content is made to be significantly increased.Analysis precision is improved, while identical in precision, then can save a large amount of samples. |
