空间冲击载荷下的滤波减速器动力学可靠性分析

In this paper, the dynamic reliability assessment for a filter reducer is performed by accounting for the shocking from the space environment. Gears are considered as the lumped mass and meanwhile the mesh between different gears are equivalent to a dynamic system consisted of springs and dampers during constructing the dynamic model. Newmark method is employed to resolve the differential equations, and then the additional acceleration could be obtained caused by the shocking to the filter reducer. The dynamic reliability analysis is conducted with simulation method.
