Thank you for your interest in our product catalogue.
For more than 60 years, Geislinger has been a solid partner for the development and the optimization of drivetrain systems. Our in-house software solutions and test beds enable us to have a virtual simulation of the drivetrain behavior and therefore perform a realistic testing of our products. With our Geislinger monitoring system, an on-site testing of the torsional vibration situation of your drivetrain is possible. This enables a visualization of the positive impact of our products on the dynamic behavior of your powertrain.
Engine & Powertrain Development
Our in-house programmed TVC software and longtime simulation- and drivetrain modelling experience in different fields enable us to gather viable data for creating accurate torsional vibration analysis of your application to mitigate the operational risks.
By comparing the continuously collected data to a digital twin, Geislinger is able to optimize the operational conditions of each system at an early stage to help customers maintain a safe operation with the lowest cost of ownership. This includes a wide range of applications like complex marine applications including ice class projects and alternative powertrains like hybrid propulsion, wind drivetrains, rail and other off-highway applications and high-performance racing car drivelines. Due to our vast experience and engineering know-how, Geislinger is the perfect development partner for engine OEMs, system designers and engineering consultants.
Testbed Appplications
Testbed applications for engine manufactures and research facilities must often run through different test modes at different engine speeds and loads.
This often influences the dynamic drivetrain behavior of the whole system and leads to unexpected and harmful driveline loads. Tailor-made Geislinger products like the Geislinger torsional elastic couplings and the Geislinger torsional vibration dampers significantly reduce the dynamic drivetrain behavior in your test bed system and keep it running smoothly. Geislinger protects the driveline components and offers reliable product solutions with consistent performance over the products’ lifetime. Some application examples are single cylinder engine test beds, dynamic test beds, waterbrakes, performance and endurance test cell configurations as well as acoustic test beds.
Measurement & Monitoring
The early detection of abnormal operating conditions is the decisive factor for a secure and reliable operation of your powertrain system.
To keep downtimes to a minimum and to ensure high profitability, the Geislinger Monitoring System continuously monitors and measures torsional vibrations to recognize functional deviations. By comparing the continuously collected data to a digital twin, Geislinger is able to optimize the operational conditions of each system at an early stage to help customers maintain a safe operation with the lowest cost of ownership. The highly advanced sensors and algorithms of the Geislinger Monitoring System measure torsional and axial vibrations, oil pressure, oil temperature, they detect misfiring and are used for power monitoring. Our newly developed Geislinger Analytics Platform is the door-opener for the use of big data and data science to improve operational safety and reliability even further.
Acoustic Solutions
The variety of operating modes for conventional, hybrid and electric systems cause complex torsional vibration situations and high acoustic requirements and therefore require innovative coupling solutions.
Due to our holistic system approach, Geislinger can provide innovative powertrain solutions. Modern couplings for ships and especially for mega yachts must fulfill various tasks. Located between the gearbox and the propeller shaft, they must minimize the transfer of structure-borne noise while transmitting high torque levels. To minimize the transfer of structure-borne noise in ships from the engines into the ship structure, ship cabins and the environment, the secondary path from the engine via the gearbox and the propeller shaft have become more and more important. In such drivetrains, the lightweight Geislinger SILENCO® acoustic coupling does not only handle the misalignment, but they can also be used to minimize structure-borne noise. Due to the material impedances and damping factors, lightweight couplings made from composite material and elastomer layers are an efficient and lightweight option with electric insulation properties to minimize the noise transfer. For the development of acoustic couplings that meet your specific application requirements and to confirm the predicted transmission loss, Geislinger has built an innovative acoustic test lab with state-of-the-art acoustic test beds.
