Cyclic Endurance Testing of Automobile Parts Endurance Evaluation of Automobile Parts by Frequency Sweep and Resonance Frequency Tracking Test

Shimadzu JF Series Force Simulators / Compact Hydraulic Actuators Frequency sweep and resonance frequency tracking tests can be performed using Servo Controllers 4830.
This series can evaluate the endurance of automobile parts and other Dynamic characteristics Frequency can be changed in stages so that dynamic Resonance frequency detection Resonance frequency is detected in just several
products by actually applying a cyclic load. characteristics at each frequency can be measured. seconds by random waves.The resonance frequency

Actuator Size and Weight
Model Stroke ±25mm ±50mm ±100mm ±150mm Lightweight Endurance testing based on resonance frequency
can be performed after detection.
Weight * 1 15kg 17kg 20kg 26kg
JF5kN The actuator (20 kN ±100 mm) weighs only 25 kg (40 % less than previous Shimadzu
Overall Length * 2 440mm 565mm 815mm 1065mm models), which means less influence of the actuator deadweight on the specimen when a Resonance 1 Resonance 2

The actuator is compact and takes up less space when installed on the specimen.
Weight * 1 36kg 40kg 47kg 54kg Easy Operation testing can also be performed.
JF30kN
Overall Length * 2 590mm 715mm 965mm 1215mm It is compact and lightweight, which makes it easy to carry and install. One-touch couplers
are used so connections to the hydraulic system are easy to perform.
*1 The weight includes the load cell and servo valve. Diverse Testing System
*2 The overall length is the dimension at the central position, with the load cell attached. A portable hydraulic unit, Servo Controller 4830, and test jigs can be combined on the
actuator to configure the required system. Other resonance frequencies can be selected by dragging with the mouse.
Fixed acceleration
Acceleration and strain amplitude can be set directly. Control is performed so that the
