The Thermal Stress Analysis of Langmuir Probe and its Heat Dissipation System Based on the Finite Element Method
Keyword(s):
In this paper, temperature field and stress field have been simulated on a Langmuir Probe and its dissipation system in certain diagnostic equipment under intense radiation in use of Abaqus. The results show that there are strongest thermal stresses on the ceramic barrels inside the system, which would be extremely easy to get broken. The reasons to have such dreadful stresses are discussed in the paper. And improving suggestions to avoid extra stresses are put forward for the structure design of Langmuir Probe and its heat dissipation system due to the simulation results.
