刚性安装座
一种支撑叠堆并使其与支撑结构隔离的装置，它采用具有高刚度的构件（通常是调谐构件），而不像使用柔性构件（如 O 形圈）的设计。由于刚性安装座在载荷下的挠度很小，因此用于叠堆承受高载荷且需要精确对中的场合。
刚性安装座包括：
Elmore 安装座
极式安装座

Rigid mount
An assembly that supports the stack and isolates it from the supporting structure by using members (often tuned) that have high stiffness (unlike designs that use compliant members -- e.g., O-rings). Because a rigid mount assembly has very little deflection under load, it is used where the stack is subjected to high loads and where precise alignment is required.
Rigid mounts include:
Elmore mount
Polar mount
