DriveTrain - Gear and Bearing Simulation Software 글 편집 글 편집 (이전 에디터)
Gear Simulation is essential for analyzing gear performance, optimizing design, and ensuring reliability in various industries like automotive, robotics, and machinery.
Gear train simulation using RecurDyn/DriveTrain
RecurDyn/DriveTrain is a gear simulation software that enables users to model and simulate the components of a drivetrain consisting of gears, bearings, shaft, and other components (especially for gear simulation and bearing simulation). It consists of 3 toolkits: GearKS, BearingKS, and Shaft. Users can easily simulate and analyze drivetrain systems with specialized modelers that can easily create gears, bearings, and shafts, a specialized solver, and dedicated post-processing.
In particular, GearKS and BearingKS have been developed through the technical partnership with Gleason’s KISSsoft . This allows users to accurately capture not only transmission error for noise and vibration evaluation but also other results by using the RecurDyn's dynamic solver and KISSsoft's Gear Analytic Contact.
*KISSsoft provides specialized libraries for gear simulation and bearing simulation.
*RecurDyn/DriveTrain is a gear simulation software equipped with world-class dynamic solver and gear analytic contact.
RecurDyn/GearKS provides an intuitive Gear Modeler and built-in KISSsoft UI for gear simulation. It supports Spur, Helical, and Planetary Gear, enabling analyses with detailed gear geometries. This gear simulation toolkit predicts accurate Transmission Errors through theory-based contact specialized for gears.
