SimDriveline Model and simulate one-dimensional mechanical systems SimDriveline™ provides component libraries for modeling and simulating one-dimensional mechanical systems. It includes models of rotational and translational components, such as worm gears, planetary gears, lead screws, and clutches. You can use these components to model the transmission of mechanical power in helicopter drivetrains, industrial machinery, vehicle powertrains, and other applications. Automotive components, such as engines, tires, transmissions, and torque converters, are also included. SimDriveline models can be converted into C code for real-time testing of controller hardware. Learn more about physical modeling. Key Features ▪ Common gear configuration models, including planetary, differential, and worm gears with meshing and viscous losses ▪ Clutch models, including cone, disk friction, unidirectional, and dog clutch ▪ Vehicle component models, including engine, tire, torque converter, and vehicle dynamics models ▪ Models of translational elements, including leadscrew, rack and pinion, and translational friction ▪ Ideal and nonideal model variants, enabling adjustment of model fidelity ▪ Ability to extend component libraries using the Simscape language ▪ Ability to specify units for parameters and variables, with automatic unit conversion ▪ Support for C-code generation from SimDriveline models (with Simulink Coder™) Modeling a Vehicle Powertrain 4:28 Model a vehicle powertrain, including gears, tires, engine, and longitudinal vehicle dynamics. You can use SimDriveline to optimize system-level performance and to create plant models for control design. The models you create support your entire development process, including hardware-in-the-loop simulations.

Creating Custom Components You can add components from other physical modeling products to your SimDriveline model. The foundation library in Simscape™ contains blocks in other physical domains, such as electrical, hydraulic, and thermal. Integrating these domains into your SimDriveline model using physical connections helps expand your model's equations 1 Simscape Language: Mechanical Example 3:42 k == tablelookup (> Model custom mechanical components using the Simscape™ language.

Maximizing Fuel Economy 1:48 Speed up the process of tuning shift schedule calibrations using optimization algorithms and parallel computing. You can use optimization algorithms to automatically tune parameters in simulation. This approach enables you, for example, to find designs that minimize weight or minimize fuel consumption. To accelerate optimization tasks and other design studies that require many simulations, you can use Parallel Computing Toolbox™ to distribute your SimDriveline simulations across multiple cores or a cluster of computers. Shorten Parameter Sweeps with Parallel...

A stiff fixed-step solver is used for the physical system (shaded pink) and an independent fixed-step solver is used for the rest the model (shaded blue). You can generate C code from your SimDriveline models using Simulink Coder. The generated code can be used to run HIL simulations on real-time processors that interface directly with hardware. This enables you to test your control algorithms without relying on hardware prototypes. 1 Simulating In Real...
