摘　　要：目的提高卫星热真空试验的热电偶实施效率,提升实施结果和试验结果的一致性。方法基于逆向思维的方法,将正常流程中后实施的星上工作转移至星下提前实施,即首先完成热电偶的分区和路径规划工作,再在星下完成热电偶的模板制作和焊连电连接器工作,最后在星上完成热电偶的粘贴工作。结果实现了星上工作星下化,星下工作辅线化,辅线工作单元化,并在卫星热真空试验中成功应用。结论工艺方法合理可行,操作方便,主线工作效率提升267%,现场实施一致性提高,并降低了热电偶引线损伤的可能性。Objective To improve the implementation efficiency of thermocouple for satellite thermal vacuum test,and improve the consistency of implementation result and test result.Methods The on-satellite tasks in normal process weretransferredto off-satellite operation star in advance based on reverse thinking.Firstly,partition and path planning of the thermocouple was completed.Secondly,template of thermocouple were made and welded to the electric connectors.Finally,the thermocouple was pasted onto the satellite.Results Off-satellite operation for the on-satellite tasks,subordinate line operation for the off-satellite tasks,and unit operation for the subordinate line were achieved and were successfully applied in the thermal vacuum test of satellite.Conclusion The technique is reasonable,feasible and easy to operate.In this way,the efficiency of the principle line is increased by 267%,thus improving the consistency of on-site implementation and reducing the possibility of damaging the lead of thermocouple.
