Rotating machinery testing includes numerous powerful features that combine to form a unique solution. Read more about these features below.
(H)EV Powertrain Testing
Vehicle manufacturers resort to vehicle hybridization (HEV) and electrification (EV) to achieve lower pollutant emission and fuel consumption targets. At the same time (H)EV should offer outstanding engine performance and vehicle comfort. Our testing solutions are employed for the engineering of (hybrid) electric powertrain with the purpose of gear whine reduction, powertrain integration, and PWM control strategy optimization. They also help understand CVT, ICE-engine, and electric motor interaction.
Combustion Engine Testing
Our internal combustion engine testing solutions simultaneously acquire all engine parameters required for efficient balancing of NVH and performance. The combined analysis of sound quality, torsional vibration, angle domain, combustion, and controller information saves time, increases data reliability, and maximizes insight even early in the development process.
Operational Data Collection
Delivering high-quality products requires to-the-point target setting, competitive benchmarking and physical prototype validation. With our Simcenter testing solutions, easily collect in-field and laboratory operational data for full vehicle and powertrain NVH development.
Signature Testing
Harmonic analysis is at the core of rotating machinery vibration and sound testing. Our state-of-the-art signature testing solutions include fixed sampling and synchronous order tracking to derive waterfall, order cuts, and engine maps from rpm and torque measurements in any operating condition. They make fully automated or highly interactive comparison of design variants easier than ever.
Torsional Vibration Testing
Torsional vibrations in power transmission systems induce noise and vibration disturbances that negatively impact comfort and may cause system failures. Our testing solutions help you visualize torsional vibrations, conduct high-precision rotational speed measurements on a wide range of angle and speed sensors, and analyze orders, narrowband waterfalls, and transmission errors.
