As automotive manufacturers strive to improve fuel-efficiency of their products, all components and sub-systems that go into a vehicle are under closer examination in order to minimize energy losses. In transmissions in particular, a great deal of effort is being put into assessing exactly how much power is lost, and what can be done to reduce those losses and improve overall efficiency.
Maplesoft has developed a MapleSim library of components, transmission sub-assemblies, and complete powertrain examples that show the use of these components in driveline applications. Built with guidance from several transmission manufacturers, this MapleSim library allows you to mix the best of physical models and empirical data to maximize model fidelity, optimize your designs, and improve overall vehicle fuel-efficiency.
Highlights:
- Covers all aspects of the powertrain, from the engine to the differential, wheels, and road loads
- Includes transmission configuration examples such as manual, automatic, and dual-clutch
- Provides “lossy” versions of many components that allow losses due to tooth meshing, bearing friction, and slip to be readily incorporated using external calculations and empirical look-up tables
- Supports an acausal approach to model development, so you can simply connect components together without worrying about issues such as torque/speed directions and load flow
- Allows you to modify the pre-built components to suit your specific requirements and increase the model fidelity
- Provides building blocks so you can easily create new transmission models
