Case Study

Large Displacement Range

Large Displacement Type J260/SA7M

J-series

J-series accommodates high-velocity and large-displacement testing.

Long-duration shock tests require high velocity and large displacement.
J-series is a high-functionality system that offers usability and durability with features that accommodate high-velocity and large-displacement testing.

IMV-SmartTM technology

■Expanded maximum test range
・Maximum velocity of sine force: 94 in/s ・Maximum velocity of shock force: 181 in/s ・Maximum displacement: 4.0 inp-p
■Patented upper (armature) support system PS Guide
Parallel Slope Guide is standard
■All models can be directly paired with a climatic test chamber

  • *1 Random force ratings are specified in accordance with ISO5344 conditions. Please contact IMV or your local distributor with specific test requirements.
  • *2 Power supply: 3-phase 220/480 V, 60 Hz. A transformer is required for other supply voltages.
  • *3 Breaker capacity for 480 V
  • *4 Above 2000 Hz, the force rolls-of f at a rate of -12 dB/oct.
  • *5 Specification above applies to 60 Hz. Dimensions change for 50 Hz.
  • *6 Export license is required for exporting a shaker system of over 11,240 lbf sine force.
  • *7 For high-velocity option
  • * For random vibration tests, please set the test definition of the peak value of acceleration waveform to operate at less than the maximum acceleration of shock.
  • * Frequency range values vary according to the sensor and vibration controller.
  • * Mass and dimensions may change for CE-marked systems.
