A table assembly that includes a snubber coupled to both a table and a vibration isolator. The snubber limits relative movement between the table and vibration isolator so that the isolator can more quickly damp movement by the table. The snubber reduces the settling time of the table when subjected to shock and/or vibration loads. The snubber may include one or more rollers coupled to an elastomer.

Snubber for pneumatically isolated platforms

A vibration isolator for isolating a load from a floor. The vibration isolator may have an active isolator assembly that isolates the load in a first direction and a passive isolator assembly that isolates the member in a second direction or directions. The active isolator assembly may include a single actuator that is coaxially aligned with a sensor. The sensor and actuator can be connected to a controller which together provide active isolation of the load. The passive isolator assembly may include a pendulum that is coupled to a dashpot. Providing a system with just one actuator significantly reduces the cost of the vibration isolator with respect to isolators of the prior art.

Active isolation module

A vibration isolator that has an elastomer which couples a support plate to a piston. The elastomer can provide horizontal damping of a payload that is coupled to the support plate. The piston can move within a first housing inner chamber that is in fluid communication with a second housing inner chamber. The chambers are pressurized with air that can flow to dampen vertical movement of the piston. The vibration isolator of the present invention thus provides both vertical and horizontal damping without using any oils.

Pneumatic vibration isolator utilizing an elastomeric element for isolation and attenuation of horizontal vibration

A table that includes a damper attached to a first faceplate and a second faceplate. The damper can dampen flexural loads introduced to the table by either shock or vibration. The damper may include a damping layer that is attached to a first plate and a second plate. The first plate may be cantilevered from the first faceplate. The second plate may be cantilevered from the second faceplate.

Vibration damper for optical tables and other structures

A vibration isolator with a flange that extends from a piston. The piston may be coupled to a housing by a diaphragm. The diaphragm and flange define a balancing chamber that is in fluid communication with a leveling port. The flange is separated from the housing by a gap that provides fluid communication between the balance chamber and an inner chamber within which the piston moves relative to the housing. The piston is coupled to a support plate that is attached to a payload. The leveling port may be coupled to a leveling valve that varies the pressure within the balancing chamber and inner chamber to compensate for a disturbance applied to the isolator. The flange will provide a force that is opposite to the movement of the piston. The counteracting force minimizes oscillations in the isolator caused by releveling the support plate.

Method for providing high vertical damping to pneumatic isolators during large amplitude disturbances of isolated payload

Intermittent stabilization of a load table supported by pneumatic vibration isolators is provided by determining a load shift condition, increasing passage of gas to the pneumatic vibration isolators and imposing external or internal damping on the load table in response to that load shift condition. For internal damping, the pneumatic vibration isolator is provided with damping fluid in one of its pneumatic chambers and a damping fluid friction passage is provided between that damping fluid in that one pneumatic chamber and the other pneumatic chamber.

Stabilization systems for vibration isolators

A pneumatic vibration isolation system, wherein an operating piston is displaced by vibrations relative to a chamber containing compressed gas, and automatically centers that operating piston for each inflation of the chamber with compressed gas. The isolation system may have a contoured centering guide for that piston.
