Ultra-low frequency vertical vibration isolator .

For the applications in precision measurement such as absolute gravimeter, we have designed and built an ultra-low frequency vertical vibration isolator based on LaCoste spring linkage. In the system, an arm with test mass is suspended by a mechanical extension spring, and one end of the arm is connected to the frame with flexible pivots. The displacement of the arm is detected by an optical ...

Active low frequency vertical vibration isolation .

We have constructed a system that isolates a key element of our experimental setup from vertical motions of the ground and the surrounding apparatus. This system combines the passive isolation of mechanical springs and an optical table floating on compressed air with an active system that measures the acceleration of the mass to be isolated and feeds back to a solenoid actuator to cancel this ...

Vibration Isolation Rails — Vibration isolation rails are sometimes employed in much the same capacity as the vibration isolation base, usually on smaller arrangement 9, 10 or 4 fans. They add stiffness to the mounting platform of the fan, and height saving brackets may be used if height needs to be kept to a minimum (see Figure 3). 3.

A method for vibration isolation of a vertical axis ...

4/27/2012 · This paper discusses a method for vibration isolation of a vertical axis automatic washing machine with a hydraulic balancer. First, a way to isolate vibration through a small amplitude of the suspension rod's axial force is proposed, and a base circle of a cone along which the lower joint of a suspension rod moves is discussed. Based on the circle, a geometric constraint involving the slant ...

Limiting Vibration Issues in Vertical Turbine .

Structural vibration can be a problem with most machines, particularly with vertical turbine pumps. These pumps are commonly suspended from the discharge elbow with the motor mounted above, making them difficult to stiffen and damp. With low stiffness and damping, natural vibration frequencies in the machine operating range are inevitable, as well as reliability issues from excessive vibration.
