An Integrated Measurement to Road Vibration Simulation System

Vibration tests are commonly used to design or qualify products such as electronics, auto parts, and consumer goods, and ensure they can withstand transportation and normal use or occasional vibration shocks. Many vibration tests specify random, sine, or classic shock vibration profiles. These produce vibrations from mathematically parameterized models and result in very predictive and consistent results. However it can be argued that the vibrations observed in the real world are not like any of these. For example many products will survive low level random vibrations for a long period of time, but if the test is started with a shock that moves the parts out of the designed location, then the same random vibrations can cause damage in a short time. For this reason, many manufacturers prefer to use simulated real world vibrations in a laboratory environment to test their products. This is most commonly used in the auto industry.
