Term: Raptor: Single-axis, vertical shaker
Definition: University of Texas at Austin earthquake engineering mobile shaker equipment. 1982 International Paystar model Y-1100 vertical shaker. This type of shaker is called a compression-wave (P-wave) shaker in the geophysical exploration community. The maximum vertical force output is about 120 kN. Raptor is ideal for situations where the force output of a smaller shaker is not sufficient for the desired testing application and the 3-mode shaking capabilities and/or higher force output of T-Rex are not required. Can be used in conjunction with other mobile shaker equipment to create customized testing configurations.
