Dynamic Spin Rigs (DSR) include patented technology that Test Devices has been pioneering since 2004. A DSR is a spin test system that can excite blades under centrifugal loading. Our resource breaks down everything you need to know about Dynamic Spin Rig (DSR) as well as key ingredients for successful dynamic spin testing.
As the race for improved electric drives for electric vehicles, drones, and hybrid drive/ propulsion systems accelerates, the need to design rotors that exhibit the structural integrity, proper balance, and durability to tolerate high-performance applications is becoming crucial to the advancement of eDrive technologies.
Avoid taking unnecessary risks when balancing your rotating components. This everything-you-need-to-know guide walks through what you need to know about balancing your parts.
Test Devices’ patented Crack Detection System is a Real Time Rotor Health Monitoring System for Low Cycle Fatigue (LCF) testing.
The development of jet engines and other high-speed machinery requires extensive testing to establish the integrity and useful life of high-speed rotating components. A fundamental evaluation technique for turbine engine rotors is to empirically test and validate the number of cycles the rotors can withstand, either to a predetermined number or all the way to failure. This type of test is typically referred to as a low-cycle fatigue (LCF) test.
There are two types of stress happening to a turbine blade: an alternating, or vibration, stress and a centrifugal static stress. As blades rotate, they experience natural resonant frequencies at different rpms. While vibrating, the blade is also under a centrifugal load as if it is being pulled from root to tip. For a complete stress test, all stresses should be tested for simultaneously.
An ever more rapidly accelerating trend toward pursuing more efficient gas turbines pushes the engines to hotter and more arduous operating conditions. This trend drives the need for new materials, coatings and associated modeling and testing techniques required to evaluate new component design in high temperature environments and complex stress conditions.
