Product catalog summary
Introduction
This document provides technical guidance on selecting and applying isolators for vibration control in various mechanical systems. It emphasizes the importance of matching the natural frequency of the isolator with the disturbing frequency of the application to ensure effective vibration isolation.
Airstroke Actuators
Airstroke actuators are used as alternatives to pneumatic or hydraulic cylinders in industries such as automotive, textile, and material handling. They are valued for their versatility in actuation and isolation, and their ability to function in applications like protective boots and shock absorbers. Key advantages include lower cost, durability, and maintenance-free operation.
Airmount Isolators
Airmount isolators are designed to serve as vibration isolators for equipment like lasers, microscopes, and industrial machinery. They offer excellent isolation capabilities, constant efficiency, and noise reduction, contributing to extended equipment life.
Design and Specifications
Airsprings are constructed from cord-reinforced rubber and can handle loads up to 450 kN. They operate in temperatures from –37°C to 57°C, with special compounds available for extended ranges. Proper installation and safety measures, such as providing clearance and safety stops, are crucial to prevent damage.
Control Systems
Three basic control systems are used for air suspended isolation systems: Tank Valve System, Three Point Regulated System, and Three Point Leveled System. These systems offer features like individual inflation and automatic height control.
Installation and Safety
Proper clearance and safety stops are essential to prevent excessive movement and damage. Initial installation should not rely on Airmount isolators for lifting due to lateral instability at lower heights.
Performance Considerations
Resonance and amplification can occur when forced frequency matches the natural frequency, leading to exaggerated movement. Damping and auxiliary reservoirs can improve isolation effectiveness by lowering the natural frequency.
Specifications and Procedures
Airmount isolator systems require careful consideration of the center of gravity for stability. The lateral rate decreases as the isolator's height decreases, affecting stability. Selection procedures involve assessing load capacity, isolation effectiveness, and design height.
Airstroke Actuator Selection Procedure
Selection involves determining stroke capability, calculating forces, ensuring dimensional fit, and selecting appropriate end closures and air inlet sizes.
Advantages of Airmount Isolators
Airmount isolators provide unsurpassed isolation capability, accurate height control, and versatility in various applications.
Basics of Vibration Isolation
Effective vibration isolation requires managing disturbances from environmental or equipment sources, with the disturbing frequency being a key parameter for selecting an appropriate isolator.
Sample Problem
An example involving a fan and motor demonstrates the process of selecting appropriate isolators based on load capacity and isolation effectiveness, highlighting the superior performance of the #224 isolator.
Design Considerations
Design height and safety stops are crucial to prevent over-travel during disturbances. Consulting the Engineering Manual and Design Guide is advised for precise design requirements.

There are three basic ways of controlling an air sus-pended isolation system:1. Resonance is the condition where the forced frequency ofthe vibrating system is at the natural frequency of the sus- pension. When this happens, amplification of movement occurs. So, while a machine is building up to speed and slowing down, the amplitude of movement may be exag- gerated. The longer the machine takes to go through resonance (to build up to, or slow down from full operating speed), the larger the amplitude of movement.

VIBRATING SCREEN BIN HOPPER BLOWER AND MOTOR DELICATE ELECTRONIC EQUIPMENT WASHING MACHINE > R ISOLATORS Why use an Airmount isolator, rather than acoil spring or other type of isolator? UNSURPASSED ISOLATION CAPABILITY > Airmount isolators can provide the highest degree of iso-lation of any type vibration isolator. System natural frequencies as low as 1 Hertz are available. Lower sys- tem frequencies can be accomplished by the use of an additional reservoir. In order to achieve similar results from a conventional coil spring isolator, a real deflection of 230 mm would be required. CONSTANT ISOLATION...

A detailed discussion of vibration isolation is beyond thescope of this brochure, but the general theory and terms bear some explanation.In any vibration isolation application, there will be somesource of vibration, or disturbance, that generates concern. This disturbance may be coming from the environment. An example would be a coordinate measuring machine in a metal stamping plant whose floor vibrations make deli- cate measurement impossible. The disturbance may also be generated by a device that affects the surroundings. An example of this could be a vibrating screen or power unit in an office...
