Abstract
In an embodiment, and by way of example only, a vibration isolator is used for coupling between a payload and a base and includes a rod, a magnetic damper, a first spring, and a second spring. The magnetic damper includes a movable section and stationary section. The movable section comprises a conductive material and has an opening through which the rod extends. The stationary section includes a magnet disposed around and spaced apart from the movable section and is coupled to the base. The first spring couples the movable section to the rod. The second spring is coupled to the rod and stationary section. In another embodiment, the vibration isolator also includes a voice coil actuation system.
Claims20
A vibration isolator for coupling between a payload and base, the vibration isolator comprising:
- a rod;
- a magnetic damper including a movable section and stationary section, the movable section comprises a conductive material and has an opening through which the rod extends, and the stationary section including a magnet disposed around and spaced apart from the movable section and coupled to the base;
- a first spring coupling the movable section to the rod;
- and
- a second spring coupled to the rod and stationary section.
A vibration isolator for coupling between a payload and base, the vibration isolator comprising:
- a rod;
- a voice coil actuation system including a movable section and stationary section, the movable section coupled to the rod and including a winding configured to receive current therethrough, and the stationary section spaced apart from and disposed around the movable section, wherein when current flows through the winding, a force is created between the movable section and the stationary section;
- a magnetic damper including a movable section and stationary section, the movable section comprises a conductive material and has an opening through which the rod extends, and the stationary section including a magnet disposed around and spaced apart from the movable section and coupled to the base and to the voice coil actuation system stationary section;
- a first spring coupling the movable section of the voice coil actuator system to the movable section of the magnetic damper;
- and
- a second spring coupling the rod to the base.
An isolation system comprising:
- a payload;
- a base proximate the payload;
- and
- a vibration isolator for coupling between a payload and base, wherein the vibration isolator comprises:
- a rod;
- a magnetic damper including a movable section and stationary section, the movable section comprises a conductive material and has an opening through which the rod extends, and the stationary section including a magnet disposed around and spaced apart from the movable section and coupled to the base;
- a first spring coupling the movable section to the rod;
- and
- a second spring coupled to the rod and stationary section.
