摘　　要：针对大型产品性能试验的多技术状态、小样本特点,提出了基于环境因子仿真的性能可靠性评估方法。运用仿真技术获得了环境因子的仿真结果;利用环境因子将多技术状态下的试验数据折算为产品设计状态下的性能试验数据,基于折算后的性能试验数据得到了产品性能可靠性估计。最后,通过一个仿真实例说明了折算模型具有稳健性。In view of the situation of small-sample in multi-technical states in the performance trial of equipment system, an evaluating method of performance reliability by simulation was proposed Technique of simulation was recommended to verify the distribution of performance parameters and then the environment factors were acquired, which was used to convert data in technical state A to B under which the performance test was launched. Finally, an example of applying the method was provided and the stability of the conversion model proposed was confirmed.
