Jackson, CSZ Testing Services - July 2. A key element of the new product development cycle for companies in the automotive, military, medical device, and electronics industries is shock and mechanical vibration testing. For unbiased collection of data about how a prototype will ultimately perform in its future application, as well as to determine lifespan and point of failure, it is crucial to select the third- party testing service provider whose expertise, equipment, and testing procedures are best suited to meet your needs. Here are six questions to ask when evaluating and comparing potential shock and mechanical vibration testing providers. It’s important to also consider the environment in which the tested product will ultimately be used. Detailing the anticipated types of stresses will help your testing laboratory determine the types of mechanical vibration and shock testing methodologies to employ in simulating actual use, as well as any extremes. Measurement Of Vibration Pdf ReaderOften overlooked—but critically important to yield the most accurate data—is the need to use the actual fixturing that will ultimately be employed to secure the prototype during testing. Always provide the testing laboratory with any supporting or integral components that will be associated with the item. If those pieces are not available, be sure that the testing facility has the means to reproduce those fixturing items as closely as possible to the relevant specifications so they can best replicate the application. Variables include the specification standard(s) your prototype is being tested to, the number of samples being tested (either simultaneously or in sequence), and the number of setups required. If your testing company operates more than one laboratory, your wait time may be reduced. Another way to save time is to invest in a face- to- face meeting to discuss your testing needs and parameters, if possible. Although it is extremely helpful for your testing provider to receive a written document detailing your requirements, a sit down discussion can often result in both time and cost savings. The most common vibration and mechanical shock testing capabilities include random, sinusoidal, mixed mode, transportation, packaging, and gunfire.

CSI 9420 Wireless Vibration Transmitter. A measurement of 20g indicates a serious problem in the bearing, even though overall vibration levels might not. Inquire about your facility’s vibration testing capabilities—including force output, axes, displacement, velocity, acceleration (sinusoidal and random), and frequency range—to ensure that they can generate the simulation that will produce the most relevant results to your needs. Although certain facilities, including ours, can induce mechanical shocks up to 1. Gs and random vibration up to 4. Gs, the equipment itself may have some limitations, such as the maximum weight of the item to be tested. Inquire about your service provider’s testing chamber capabilities. Further, depending on your testing lab’s abilities, additional parameters can be applied in conjunction with your mechanical shock and vibration testing specifications. A properly- equipped facility can add extreme temperatures (either gradually or rapidly to simulate thermal shock), force, humidity, corrosion, and salt spray conditions to your testing process as required by the test specifications.
