本文件根据试验要求，为多轴环境试验的振动产生设备的选择提供了指导。 本文所述的多轴环境试验设备是指具有一个以上自由度受控振动的振动试验系统，包括线性振动和角振动。在本文件中，假设每个所需自由度有一个或多个励磁机。 该指南涵盖了以下方面的选择: —？励磁机的数量、类型和型号， —？连接器的数量、类型和型号， —？系统配置，以及 —？一些组件。

This document gives guidance for the selection of vibration generating equipment for multi-axial environmental testing, depending on the test requirements. Multi-axial environmental test equipment dealt with in this document refers to a vibration test system having controlled vibration of more than one degree of freedom, including linear vibration and angular vibration. In this document, one or more exciter per desired degree of freedom is supposed. The guidance covers such aspects of selection as —？number, type and models of exciters, —？number, type and models of connectors, —？system configuration, and —？some components.
