Evaluate and balance key vehicle attributes, such as performance, fuel economy, drivability, comfort and reliability. A combination of generic and application-oriented models in Simcenter helps you design manual, robotized, automatic and continuously-variable transmissions as well as multiple hybrid and electric powertrain architectures. Simcenter helps you address the entire design cycle thanks to its scalable modeling options, from functional to high-fidelity models that can handle high-frequency behavior and nonlinear phenomena.
Whereas simulations are usually only in the time domain, linear analysis also helps you analyze the system in the frequency domain, and reduce the model for faster simulations or real-time applications. High-fidelity plant models built with Simcenter enable mechanical design and control design departments to test controls virtually, significantly reducing the required number of prototypes and tests.
Predict transmission systems performance and meet fuel economy, drivability & noise, vibration and harshness (NVH) objectives.
Rapidly model your driveline, engine and gearbox, including their components such as synchronizers, planetary geartrains, clutches and dual-mass flywheels. With Simcenter, you can easily model the entire transmission, including all actuators and controllers, and evaluate their interactions during the powertrain and driveline integration in the chassis. You can reproduce all physical phenomena in order to optimize your design, and in this way shorten the calibration phase.
Maximize driver comfort by delivering optimal shift transmission quality and engine torque delivery transients. Using Simcenter, you can study the entire physics and controls strategies of gear shifting for every kind of transmission architecture in order to avoid severe oscillations. By simulating tip-in, tip-out, takeoff, and engine stop-and-start scenarios, you can virtually evaluate vehicle drivability and balance it with fuel economy and performance.
Understand the root causes of noise and vibration generated by a combination of linear and nonlinear powertrain systems. Simcenter helps you address engineering challenges related to engine torque oscillations, gear rattle, driveline modes excitation, friction self-excitation, hydraulic dynamics and controls strategies. You can analyze phenomena such as booming, clunk, clutch judder or shuffle, and then optimize components, subsystems and overall system architecture.
Optimize gear shifting as well as hybrid strategies to reduce fuel consumption while still providing a consistent output power curve within the engine's best operating range and reduce mechanical losses. Advanced Simcenter models for loss estimation in gears and bearings allow you to identify the main sources of loss in your transmission at any operating point and to point out the components that have to be optimized.
