| Abstract: |
| The relevant theories of new ammunition and accelerated testing are introduced, and the current status of accelerated testing in new ammunition research at home and abroad is analyzed. The stages of the full life cycle of the new ammunition are divided, and the application of accelerated tests in different stages is outlined. Two types of accelerated life test and accelerated degradation test are distinguished, and the processing flow of accelerated test data is described. The life distribution model, acceleration model and parameter estimation are briefly summarized respectively, and the types of common models, general methods of hypothesis testing and parameter estimation are pointed out. Finally, the status of accelerated testing and the next research direction are pointed out. |
