Vibration Testing at JTL America

Vibration testing is a method of testing to ensure that products meet durability, performance, and most importantly, safety standards. Real world conditions cause vibration. The three areas of vibration are structure born, fluid born, and air born. Within these three areas’ we use the source, path, and receiver model. First, we look for the source of the vibration. Next, we study the path of the vibration. This is how the vibration travels through the structure. And finally the receiver. The receiver is the person using the product. This type of testing has many applications. Common applications include quality/durability testing for: automotive vehicles and parts, manufacturing plants, aerospace, material engineering departments, research/development, and more.

The engineers at JTL America offer cutting edge vibration testing services as well as a variety of other industrial testing solutions to ensure your product meets all necessary quality and safety standards for your industry. We possess the equipment, experience, certifications, and expertise to adequately test products against realistic environmental conditions as well as various vibration frequencies.

Testing Capabilities

The vibration test systems offered by JTL America can be performed with a combination of conditions. For example, our vibration test systems can be paired with temperature and humidity testing for combined vibration and environmental testing. These test systems can also be employed while the product is in use. Below is a list of our major vibration test capabilities.

Random vibration testing involves exposing a product to all frequencies at the same time. This type of vibration test is the most common, as it’s generally considered the closest replication to a real-world environment.

Sine vibration testing applies only one specific frequency at a time. This type of vibration test is used to isolate and understand a product’s response to one variable.

Sine sweep testing sweeps through both low and high frequencies. In other words, this tests the endurance of an object against frequencies of varying intensity.

Sine-on-random vibration testing is a “mixed mode” of testing. This means, the test is used to emulate the vibration environment of structures where there’s broadband and cyclic/narrowband energy.

Testing objects against shock pulses is different from testing them against vibrations. To put this in perspective, shock testing involves measuring an object’s ability to withstand short and intense bursts of force and/or temperature changes as opposed to consistent vibration frequencies. This type of test is commonly employed on objects that undergo significant amounts of handling & transportation. During transportation two common shock responses are pothole, and collision shock impacts.

Temperature shock testing measures an object’s durability against significant temperature changes. On the other hand, mechanical shock testing involves applying high levels of force to test the object’s physical durability and functionality after exposure to the test(s).

Testing a product against environmental conditions such as temperature is necessary to assess what type of conditions the product can withstand. For example, when certain devices are exposed to rapid and/or extreme temperature changes, the device may experience thermal shock. In other words, components of the object may expand/contract and cause complications. The test chambers used at JTL America accurately simulate any necessary condition that a device may encounter.

The combination of vibration and environmental testing provides a broader range of conditions to measure an object’s reliability. This is often necessary in order to accurately simulate realistic conditions the object may encounter. The testing facilities at JTL America possess the equipment, experience, and expertise to adequately test products against environmental conditions as well as various vibration frequencies.

The vibration testing fixture is a critical component to the test. Our engineers are experts in the evaluation of testing fixtures.

Resonance search, track and dwell testing (RSTD testing) is an important test related to the durability/fatigue testing of a product.

Vibration fixture design and build has always been challenging for test engineers. The fixture must be robust enough to hold the sample, and not deteriorate under normal testing conditions. Fixture must also be light enough to avoid excessive weight. In the design phase FEA analysis can help with the prediction of resonance prior to building the fixture. JTL America’s experts can help with vibration fixture design.
