A shaker is a device used in vibration testing to excite the structure, either for endurance testing or modal testing. Sample layout of a modal testing system References
A controller is configured to activate the actuators in and around the point of contact. The actuators at the point of contact induces waveforms to produce vibration. However, since there are multiple actuators around the point of contact, the vibration can propagate to other locations, thus limiting the localization effect. This is why a ...
Bustec is a company that designs and manufactures instrumentation for high-performance data acquisition and instrument control.The company's products serve applications that include engine testing, automotive and missile testing, wind tunnel data acquisition and control, acoustics, vibration applications, aircraft component testing and more.
The Rumble Pak (Japanese: 振動パック, Hepburn: Shindō Pakku) is a removable device from Nintendo that provides force feedback while playing video games. Games that support the Rumble Pak cause it to vibrate in select situations, such as when firing a weapon or receiving damage, to immerse the player in the game.
The controller was bundled with all new systems from launch, until the introduction of the 80 GB (CECHKxx, CECHLxx & CECHMxx) model, which substituted the Sixaxis with the new DualShock 3 which added a vibration feature while retaining the design, features and functionality of the Sixaxis. The Sixaxis controller was later phased out and ...
A shaker is a device that excites the object or structure according to its amplified input signal. Several input signals are available for modal testing, but the sine sweep and random frequency vibration profiles are by far the most commonly used signals. Small objects or structures can be attached directly to the shaker table. With some types ...

Implementation economy is one primary advantage of ambient vibration tests as only the (output) vibration of the structure needs to be measured. This is particularly attractive for civil engineering structures (e.g., buildings, bridges) where it can be expensive or disruptive to carry out free vibration or forced vibration tests (with known input).
