1 Scope

This document specifies the technical requirements, inspection rules, marking, packaging, transportation and storage of the electric vibration table double-table parallel excitation vibration test system. The inspection method of the double-stage parallel-excitation vibration test system of the electrodynamic shaker is described. This document applies to the manufacture of a dual-stage parallel-excitation vibration test system for electric vibration tables (hereinafter referred to as the "dual-stage system"). The electric vibration test system consisting of multiple parallel-excited devices in the same direction shall be implemented for reference.
