Description
Summary:High reliability is required for the deployment of the transformable structures as this process is crucial for successful spacecraft mission. Computational evaluation of the reliability parameters for the deployment is of a great importance as it is not possible to fully reproduce the real conditions of outer space during ground-based tests. The presented approach to estimate the probability of failure-free deployment is based on the condition of exceeding the driving torque over the resisting moment at each of the angular positions of the structure. The approach was used to compute the reliability functions for deployment of a space reflector. The calculations were carried out based on kinematic and dynamic analysis of the structure.
