船用电子设备可靠性加速试验方法研究

Research on Accelerated Test Method for Marine Electronic Equipment

针对高可靠长寿命船用电子设备的可靠性指标验证需求,以GJB 899A-2009和《海军电子装备可靠性鉴定试验实施方法(2002)》中确定的舱内有温控的电子设备的试验剖面为基准剖面,确定了应力的加速模型和加速因子,结合产品制定了加速试验剖面,并形成了加速试验方法,为实现高可靠船用电子设备可靠性指标的快速验证提供了有效的方法。

Aiming at the reliability index verification requirements of high-reliability and longlife marine electronic equipment,and taking the test profile of electronic equipment with temperature control in the cabin determined in GJB 899 A-2009 and"The Reliability Evaluation Test Implementation Method for Naval Electronic Equipment(2002)"as the baseline profie,the acceleration model and acceleration factor of the stress are determined,and the acceleration test profile is formulated in combination with the product,and the acceleration test method is developed,which provides an effective method for the rapid verification of the reliability index of high-reliability marine electronic equipment.
