The Importance Of Choosing The Right Vibration Shaker System For Your Specific Application

Failure testing is an inherent part of the engineering and design process. Everything that we design is subject to a number of forces throughout its lifetime. Some of these forces will be constant, but light, while others will occur suddenly and have a high impact when they do. The most important factor in choosing vibration test systems is that it simulates as closely as possible the forces that will affect the final design. A vibration shaker system must be able to accurately mimic the stresses and forces that will assault the final project.

The purpose of using this test is to help determine how the continual forces that impact the final design will affect its functioning and longevity. It must be able to mimic those forces in terms of force, direction, and wave motion. There are several types of systems available that include both controlled and uncontrolled techniques.

Uncontrolled techniques include vibration shaker system forms that are found in nature such as waves, engines, sirens, and vibration due to vehicles on road services. Uncontrolled vibration test shaker systems are realistic in terms of mimicking the stresses that the device will be subjected to in its natural life span. However, this type makes it difficult to make projections as to the performance of the system in the future because the stresses will occur erratically and unpredictably. It is difficult to control the test conditions with a natural vibration shaker system.

A controlled test makes it easier to measure and predict how the system will perform over time. The structure and the surface of the structure are an important element in selecting the proper vibration shaker system to produce realistic results. Structures that are linear test result in modal estimates that are more reliable in terms of the amplitude of each impact by the vibration test shaker. Bolts or rivets can impact the modal variation of the vibration shaker system. A homogeneous structure will produce the most reliable results.

Large size vibration test systems are available when higher forces are expected on the structure. The vibration shaker system can also be found in very low impact ranges for testing small electronics or other tiny structures. The purpose of the vibration test system is to determine how the structure will function over time. The vibration shaker system will allow engineers to determine how it will perform both under normal test circumstances and under unusual stresses. There many considerations to making certain that the right vibration test system is chosen for the application. It must realistically mimic what will happen to the structure naturally, but it must also be able to produce results that are reliable and with as little variation as possible for maximum control conditions. Vibration shaker systems are used to test almost everything from very large structures to very tiny structures. Forces vary and must be anticipated so that the most realistic choice in vibration test equipment can be made. It must be stable over a number of frequencies and in a number of control conditions in order to accurately represent the forces that exist in nature.
