TORSIONAL VIBRATION ANALYSIS OF MARINE ENGINES

In addition to the automotive and commercial vehicle sectors, the reduction of greenhouse gases is also under discussion in maritime transport. The demand for low-emission marine engines through optimized drive trains is becoming louder. In addition to optimizing fuel consumption, development engineers are also focusing on the durability of powertrains. Torsional vibrations in the powertrain lead to increased wear and tear and pollutant emissions. In order to reduce these, high demands are placed on precise measurement and analysis technology.

Torsional vibration investigations of marine engines place very special demands on measurement technology. High reliability and robustness, e.g. for mobile use at sea, are necessary to be able to carry out reliable measurements under the most difficult conditions.

TIMING AND AUXILIARY DRIVE

The optimization of timing and auxiliary drives  requires reliable vibration measurements and analyses of the individual components of the belt or chain drive. With our measuring system, we guarantee precise, reliable and fast analysis results of slip analysis, tension tuning as well as resonance and stress analysis.

TRANSMISSION

In the development of marine engines, noise reduction in the transmission is an important development goal. Rattle and rattling noises occur predominantly in synchronized transmissions under torsional vibrations or when excited by gear teeth. We provide you with a powerful, high-resolution measuring system and engineering know-how with which you can check gear units for noise and perform vibration analyses.

VALVE TRAIN

Valve train systems control charge changes and are therefore a key factor in achieving emission and consumption targets. The components of the valve train system are exposed to high loads due to mechanical forces and temperatures. To avoid this, you must measure them precisely and adjust them optimally. We provide you with market-leading measurement technology for this purpose. Important analyses are stroke, speed and acceleration, opening and closing behaviour and a resonance and stress analysis.

CLUTCH, TORSION DAMPER AND FLYWHEEL

For the design, tuning, optimization and monitoring of couplings, torsion dampers and flywheels you use the mobile, compact ROTEC systems.
