摘　　要：为了更加便捷地开展航天器各项大型试验和测试工作,研制了一种电子负载模拟器;电子负载模拟器能够模拟航天器电气系统的压力传感器、电磁阀、自锁阀、温度传感器、火工品等负载的电压和电流信号特性,并完成负载电压的采集和负载通电时间的统计,同时将所有功能模块集成到一个标准机箱中,所有电气信号接口通过若干接插件汇总对外进行连接,各功能模块通过上位机软件进行通信和控制;电子负载模拟器参与了某型号航天器的模飞测试工作,测试数据准确无误且性能稳定,既验证了上游驱动电路的电气匹配特性,又节省了梳理负载电缆和插拔接插件的繁琐性,同时也降低了人员频繁插拔接插件的出错概率。In order to test the aerocraft conveniently develop various large-scale experiments and texts os spacecraft,An electronic load simulator is developed.Aerocraft sensor voltage signals of pressure sensor,electromagnetic valve,selt locking valve,temperature sensor,initiating explosive devices can be simulated.The voltage and current signal of valve and detonator can also be simulated.The correlative voltage signal and time signal can be gathered.All function modules are integrated into one standard device.All external interface of the electric signal is collected in some plugs.Each module communicates and controls throught the upper computer software The electronic load simulator is used in testing the aerocraft.The test data is accurate and stable.The electric matching characteristic of driving circuit is validated.The complex process of connecting numerous cables and plugs is simplied.At the same time,the probability of the false connecting is reduced greatly.
