Cyclic Endurance Testing of Automobile Parts  Endurance Evaluation of Automobile Parts by Frequency Sweep and Resonance Frequency Tracking Test
 JF Series Force Simulators / Compact Hydraulic Actuators  Frequency sweep and resonance frequency tracking tests can be performed using Servo Controllers 4830.

 Lightweight
 The actuator (20 kN ±100 mm) weighs only 25 kg (40 % less than previous Shimadzu models), which means
 less influence of the actuator deadweight on the specimen when a dynamic load is applied.   Endurance testing based on resonance frequency
 Compact                                                                can be performed after detection.
 The actuator is compact and takes up less space when installed on the specimen.

 The precision of endurance and dynamic strength
 evaluation can be dramatically improved from raw materials
 to actual products.
 It can also be connected to control various Shimadzu
 fatigue/endurance testing machines as well as those made
 by other manufacturers.
