| Objective To design and verify simulation method of step-down-stress accelerated life test(SDSALT), in order to provide theoretical support for other simulation and analysis. Methods According to the basic principle of SDSALT, simulation procedure of test data was analyzed by Monte-Carlo. The simulation error was obtained by comparing the simulation result and the known parameter. Results The error between the simulation result and the given parameter was 0.732% . Conclusion The simulation error was acceptable, which proved that this simulation method and its verification method were effective, ensuring the feasibility of simulation. |
