由于受所处载体空间的限制，电子设备在不同载体中需要以不同方向进行安装。因此必须解决电子设备在不同方向安装时隔振系统的固有频率变化问题，才能保证设备的性能稳定。文中介绍了采用活动铰支承加轴向与径向弹性元件的典型结构来设计多向安装隔振器的方法。在隔振器力学模型分析的基础上，利用能量法推导出其固有频率的计算公式。通过对侧装安装方式典型实例的试验，验证其计算公式的正确性。另外，试验输入与输出的对比表明，该多向安装隔振器在三坐标方向实现了解耦设计，解决了多向安装隔振器的隔振缓冲难题。该多向安装隔振器的设计分析计算方法为类似隔振器的设计计算提供了理论指导。

Electronic equipment should be installed in different directions in different carriers because of the lim- ited installation space in these carriers. So there must be a way to control the change of the inherent frequency of the isolator in different directions to ensure the performance and stability of the equipment. This paper intro- duces a method of designing multi-directional installation vibration isolator with hinge and elastic elements in ax- ial and radial directions. Based on the analysis of the mechanical model of the isolator, the formula of its inher- ent frequency is deduced using energy method. This formula is verified by typical lateral test. In addition, com- paring the input and output of the test shows that vibration decoupling is realized in three coordinate directions for the isolator. This formula of inherent frequency will be an effective reference for other similar designs.
