Servohydraulic Dynamic and Fatigue Test Systems

General Purpose Hydraulic Fatigue

Servohydraulic Dynamic and Fatigue Test Systems are the workhorse of any laboratory.  They can perform a wide variety of low and high cycle fatigue, crack propagation, fracture toughness and other dynamic tests. Each system can be readily configured with appropriate sized servo valve, manifold and hydraulic power unit to suit the particular application.

Product Details

All systems are equipped with the advanced features of the Controller, Console Software and Grande’s unique fatigue-rated  load cells. 2 Dynamic Testing Software provides the backbone for running many dynamic tests. Other application specific software modules, such as Grande’s Fracture Mechanics Suite, allows other standardized tests to be run.These dynamic systems, when combined with GRANDE Software and appropriate accessories, are ideal for running a variety of static tensile, compression, flexure, peel, tear and friction tests.
