Follow this simple three-step procedure to select the proper Labworks vibration system for your application. 1. Determine the payload weight Add the weight of the test article to any adaptor or fixture that may be required to fasten it to the shakers armature head. Additional holes cannot be drilled in the armature head, therefore an adaptor may be required and its weight must be included in the payload weight. Be sure to include the weight of any other components that will move with the test vibration such as cables, connectors, hold down bolts, etc. 2. Determine the required vibration acceleration Convert your vibration specification data into acceleration units of g’s peak for sine testing or g’s rms for random testing. Remember: 1 g = 32.2 ft/sec2 = 9.8 m/sec2. Determine the maximum displacement and acceleration that will be required for the desired testing. If either of these is not known, it can be determined by referring to the engineering information section of this catalog. 3. Select a Labworks system using either the Sine or Random Vibration Capabilities charts below Plot the point that corresponds to your payload weight and required acceleration. Your testing can be done with any system whose capability line passes to the right and above your plotted requirements point. Refer to the System Components/Specifications table below to insure that the system you have selected has adequate peak-to-peak displacement and frequency range capability. Refer to the engineering section of this site for additional detailed information. Have a question or need some help? Fill out the Selection Form or call us and talk to a vibration engineer for special applications or just to insure your selection. |
