Avoid clutch judder early in automatic transmission design
Clutch judder is caused by the gripping and slipping of the clutch components during lockup and is responsible for a poor driving experience. Learn how to avoid clutch judder in your automatic transmission design in four process steps.
In downsized engines, the torque converter clutch mechanism of an automatic gearbox locks up as early as possible. This mechanism delivers higher torques at lower engine speeds. A judder may occur, which causes drivers' discomfort.
The Simcenter engineers have developed a method to help predict the occurrence of the judder phenomenon early in the development process of a new automatic transmission. This white paper describes the four steps to deliver a judder-free driving experience.

Relying on years of engineering experience, the Simcenter engineers have developed a four-step process to optimize the design of an automatic transmission.
Download the white paper now and gain a better understanding of this 4-step process. Learn how to apply the Simcenter best practices to your own automatic transmission design process.
Optimizing the NVH performance of an automatic gearbox early on saves engineers a great deal of time and effort. However, NVH issues may still arise at a later stage, when the transmission gets integrated into the full vehicle. Manufacturers needs solutions to shift the workload from the prototype testing phase to the system simulation stage and reduce the risk of late NVH troubleshooting.
The model-based development (MBD) approach pushes the boundaries of vehicle NVH performance optimization, from the driver’s input to the target’s evaluation, from the concept to the full vehicle verification. This approach helps solve not only clutch judder issues but also, booming noise, rattle, tip-in/tip-out or engine start-stop vibrations, electric motor torque ripple, and many other NVH and acoustics problems. MBD empowers automotive OEMs and suppliers to better evaluate multiple vehicles’ architectures and variants while reducing development time and costs.
Watch the on-demand webinar to understand how a model-based development approach pushes the boundaries of evaluating NVH performance.
Not affected by any judder phenomenon but still curious about innovative engineering solutions? Simcenter is the right companion for engineers eager to optimize the NVH and acoustics performance of conventional powertrains.
