Boosting productivity in gearbox engineering using a revolutionary approach to multibody simulation

Modeling and parameterizing a gearbox in a multibody simulation environment is traditionally a tedious and error-prone manual process. Typically, it takes up to several days for model preparation and simulation of the nonlinear dynamics to obtain system-level loads.

This paper introduces the Simcenter 3D Motion Transmission Builder, a software tool to compose and simulate a multibody simulation model of the transmission, at any stage of the development, more accurately, and in approximately 1 hour. Illustrated by several industrially relevant results, it describes how to analyse transmissions at system-level and achieve better performance in terms of efficiency, noise and reliability.

Siemens PLM Software revisited the numerical approach to drivetrain simulation. The new solver architecture is designed to enable the user to perform dynamic multibody simulation according to three different levels of fidelity for gear contact. This flexibility allows the design engineer to select the appropriate accuracy in the model for the performance engineering predictions of interest. 

Download this white paper to understand how you can use Simcenter 3D Motion Transmission Builder to:

  • Capture detailed, yet computationally efficient non-linear system dynamics
  • Accurately predict system behaviour for NVH, transient, durability and other analyses
  • Increase productivity by choosing from a comprehensive set of contact methods
