Abstract

According to the design requirement of the deployable mechanism for Langmuir probes, a modal analysis was conducted on the mechanism to further establish a three-dimensional deployable mechanism model of Langmuir probes. Using ANSYS for finite element analysis, the structural stability, stress and strain of the deployable mechanism for Langmuir probes which are at the locking state and subjected to sinusoidal vibration and effects of temperature-induced loads were analyzed. On this basis, the values and distribution states of stress and strain were calculated to verify service life and reliability of the deployable mechanism for Langmuir probes in the space environment.
