GB/T 44401-2024 "Three-Axis Co-Vibration Electrodynamic Vibration Test Systems" applies to the manufacturing of such systems, specifying basic parameters, technical requirements, inspection rules, and other relevant content. The system consists of three electrodynamic vibration generators, power amplifiers, controllers, and other components, enabling synchronous vibration along three orthogonal axes. It clearly defines requirements such as an operating ambient temperature range of 5°C to 35°C and the absence of electromagnetic interference. The standard also specifies error limits for indicators such as frequency and acceleration in sinusoidal and random vibrations, and mandates the use of equipment such as dynamic signal analyzers for inspection, ensuring the accuracy of product reliability testing under complex working conditions.
