| Abstract: |
| 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. |
