Structural analysis of an electrodynamic shaker for spacecraft environment test

Vibration testing constitutes an essential methodology for simulating launch-induced dynamic environments to validate the mechanical reliability of spacecraft systems, with electrodynamic vibration test systems serving as the critical infrastructure for such experimental protocols. The structural dynamic characteristics of these shakers directly govern the fidelity of vibration environment replication. This investigation focuses on an electrodynamic vibration test system, employing a computational modeling framework to conduct a comprehensive structural dynamics characterization. Analytical results demonstrate the prototype’s compliance with stringent operational specifications for aerospace vibration testing. The developed methodological framework provides significant referential value for system design optimization and parametric design refinement in electrodynamic vibration equipment engineering.
