Vibration tester is an equipment widely used in the automotive industry for conducting vibration testing on various parts and accessories of automobiles. Various automotive components and their accessories are continuously subjected to vibration testing using sophisticated vibration control techniques.

Various automotive components ranging from instrument panels to seats inside the car; and from air-bag sensors to fuel injection pumps in the engine compartment, are being tested to examine vibration patterns and levels.

Test Method

Automotive vibration testing involves utilizing sine-on-random and waveform-replication techniques to accurately reproduce the actual vibrations endured in the operating environment for various purposes like design verification as well as quality control.

Use of Vibration Tester

• They are mainly used to test various automotive components like batteries, lamps, instrument panels, seats, fuel injection pumps, etc. to ascertain vibration patterns and levels.
• These test help to establish that the various components and parts will not fail under normal road conditions.
• They also help to trace noise-making mechanisms that result in annoyances like squeaks and rattles.
• It is also used to identify characteristics of the natural frequencies of vibration of automobile mirror assembly.

Applications

Vibration testers are widely used for conducting vibration tests on various automobile parts & components. Some other areas where they are used are:

• Automotive Industry
• Environmental Stress Testing
• Aerospace
• Military/Defense
• Microelectronics
