Vibration Test Fixture Design

Vibration fixture design is crucial to the development of an accurate vibration testing program. Vibration test fixtures mount the product in place during testing, and must ensure that the test faithfully replicates real-world stress conditions.

Vibration test fixtures ensure proper specimen orientation and transmit energy to the specimen during testing. They must be designed with appropriate thickness and stiffness to correspond to anticipated test levels during design and must be validated at a range of vibrational frequencies to check for unwanted responses. Element’s vibration and shock test fixture design engineers can create purpose-built custom vibration fixtures for your products.

Whether the test specimen is simple or complex, the professionals conducting your test must have a well-rounded understanding of vibration test fixture design, including the properties of the fixture materials used, their resonant frequencies, and how they may impact the testing.

Basic Vibration Test Fixtures

Element's laboratories keep a set of standard vibration table fixtures that work for a wide range of product and equipment types. Some of these include:

• Interface plates
• Tie bars
• Bookends

Basic vibration test fixtures can be quickly and easily installed, making them a popular choice for most test programs. In most of our facilities, internal machining services can be used to make basic modifications that keep tight programs on schedule.

Custom Vibration Test Fixtures

When complex load points, mechanical loads or complex specimen design necessitates custom vibration test fixture design, our testing engineers and machinists work together to create custom test fixtures tailored to your product.
