3 Terms and definitions
The terms and definitions defined in GB/T 2298 and the following apply to this document.
3.1
A test system consisting of at least three electric vibration generators capable of performing vibrations in three orthogonal axis directions simultaneously.
4 Composition of the triaxial vibration system
The triaxial vibration system consists of the following components.
a) Electric vibration generator;
b) power amplifier;
c) vibration controller;
d) Three-axis co-oscillation mechanical coupling device;
Note. A three-axis co-oscillation mechanical coupling device is a device that can synthesize unidirectional excitation in three orthogonal axis directions into three-axis simultaneous vibration.
e) Other auxiliary devices.
The schematic diagram of the triaxial vibration system is shown in Figure 1.
