Noise and vibration are key concerns in defining vehicle characteristics that affect the quality of the ride and passenger experience. Even at lower intensity levels, noise and vibration can be a cause of operational and health hazards in some cases. Beyond being a nuisance, structural vibration is a well-known cause of issues and damage in electronics, structural joints, and contributes to fatigue damage.

Rotating parts, such as motors, turbines, propulsors, power generators, and other transmission parts are ubiquitous and are common sources of undesirable noise and vibrations. Schenck specializes in helping you minimize the risk of undesirable vibration and noise from the source. Test Devices by Schenck offers engineering consultation services to guide you through design development, planning production processes for balancing your high-speed rotating parts or troubleshooting existing issues.

As a Schenck company, Test Devices has access to the world’s premier balancing and testing equipment for rotational components. Leveraging our expertise in designing, balancing, and testing high-speed rotating parts, we can help you determine the most efficient approach to address your rotor balancing and testing needs, especially in a production environment. Some of the key focus areas of our consulting services are outlined below:

Analysis of Your Rotor

centrifuge rotorWe perform numerical model-based analysis to understand the effect of manufacturing variables, such as dimensional tolerances, to assess the resulting magnitude of unbalance in the rotor.

The analysis produces a probabilistic model of unbalance distribution that may result from a specified manufacturing process and the type of rotor. Based on the analysis results, we can evaluate the feasibility of correcting the predicted amount of unbalance, as well as make a recommendation on the optimal way to design the rotor to meet your balancing requirements.

Hiring us to perform this analysis early in the design and development stage of your rotating parts will save you from the headaches associated with balancing issues – especially in the production stage.

Balance Tooling Design

Designing a tooling for rotor balancing may appear a trivial task, but this is another underappreciated area of expertise that could result in a persistent in-production problem if you are ill prepared.

Designing a good balance tooling is not limited to making a piece of precision machined shaft. The designer must understand the interaction of the tooling with the balancing machine, the detail of the interface between the tooling and the rotor, the calibration process, and its repeatability (the effect of potential error in the assembly).

If you require a real engineering solution for your rotor balancing, we are here to serve your needs.

Troubleshooting & Process Optimization

balancing of a rotorIt is not uncommon to hear that some of our customers have been living with unnecessary suffering inflicted by balancing issues for many years. Oftentimes, rotor balancing work could devolve into an “established process” of which no one knows the engineering logic behind the procedures.

“The devil is in details”, especially when it comes to precision work like rotor balancing. Having our experts look at your balancing process could uncover and alleviate recurring issues and reduce production costs. Through analysis and expertise, our specialists could help you identify the root cause of your problems, and recommend a suitable solution for both your short-term and longer-term goals.

We strive to help you achieve:

  • Optimization of the balancing process
  • Integration into the client’s production operation
  • Production of high-quality products at a reduced cost

Testing and Validating the Result

Spin testing machineAs the industry leader in high-speed rotor testing, Test Devices can help you validate the rotor behavior in an economical and expeditious manner. Beyond checking the effect of rotor unbalance at the operating speed, spin testing allows our customers to study and understand the structural instability that may result from the centrifugal load and failure mechanism of the rotor.

We can perform various types of spin tests in our state-of-the-art test facility. Typical types of spin tests are listed below:

  • Proof / overspeed test
  • Burst test
  • Low cycle fatigue (LCF) test

All these tests can be performed in varying test environments (heated/cryogenic conditions). We offer cutting-edge and the most relevant set of data and measurement techniques to help you observe and evaluate the rotor of interest. The test data like this is a key ingredient for improving and refining the design and the performance of the high-speed rotors designed for high-performance machines.

Our experts are available to consult you on designing and planning of spin tests, project management, executing the test, and deduction and analysis of the data.
