Technical Reference

This information is provided to assist design engineers faced with the challenge of protecting equipment against the damaging effects of shock and vibration.

In today's world increasingly sophisticated equipment and harsh environmental conditions mean that engineers are continually faced with the need to improve shock and vibration isolation. Electronic equipment is often considered for use in environments that are far from compatible with their original design specifications. Even if the equipment survives initial vibration testing the life expectancy and reliability will be considerably reduced unless suitable protection is provided.

Equipment installed in military vehicles, ships and aircraft is subject to severe shock conditions. Merely strengthening the equipment to withstand these conditions often means an unnecessary increase in weight, size and cost. The use of carefully selected isolators is nearly always more effective in protecting the installation.

The following information describes theory and methods that may be applied to any vibration or shock protection problem enabling engineers to hold meaningful discussions in the early stages of a design concept where it is critical to quickly establish basic parameters to asses the correct type of mounting system needed.

Should the problem be beyond the capability of a standard catalog product, we have the engineering expertise and facilities to design a special engineered solution that meets the customer's needs.
