| Abstract: |
| Objective To shorten the development cycle, save the development costs and improve the test efficiency by replacing the conventional test method with the acceleration test method. Methods By analyzing the failure mode and effects of the propulsion motor, the motor winding and the power devices of the drive module were determined as the weakest parts. Considering the underwater application environment of the product, temperature stress acceleration was adopted. The acceleration factor was calculated by the mathematical models and experimental data on winding, power devices and temperature. Results The reliability acceleration test method was designed based on 173 hours of full power work to assess the MTBF 5000 hours of the propulsion motor. Conclusion The test method can provide a reference for the similar products’ reliability acceleration test to some extent. |
