Creating Custom Components

Simscape lets you create models of custom components by using the basic elements contained in its foundation libraries.

Modeling Mechanical Components

Simscape provides mechanical building blocks for representing one-dimensional translational and rotational motion. The variables for these components are solved simultaneously with the hydraulic and electrical variables in your system. The sensor and actuator blocks for the mechanical components let you connect to more elaborate mechanical models built with SimMechanics and SimDriveline.

Modeling Electrical Components

Simscape provides electrical building blocks for representing electrical components and circuits. Simscape solves the variables for these components simultaneously with the hydraulic and mechanical variables in your system. The sensor and actuator blocks for the electrical components let you connect to more elaborate electrical models built with SimPowerSystems.

Modeling Hydraulic Components

Simscape provides hydraulic building blocks that model fundamental hydraulic effects and can be combined to create more complex hydraulic components. These blocks define the pressure/flow relationship for basic physical effects, such as fluid compressibility, fluid inertia, mechanical friction, energy transduction, and flow through basic fixed and variable orifices. You can define a fluid by entering its fluid properties. More elaborate hydraulic components are available in SimHydraulics.

Modeling Thermal Effects

Simscape provides thermal building blocks for modeling and simulating thermal effects in your system. You can model conductive, convective, and radiative heat transfer as well as the thermal mass of elements. Using thermal source blocks you can specify the temperature or heat transfer; using thermal sensor blocks you can measure the amount of heat transfer or temperature change.

Working with Physical Signals

With Simscape your models can include physical signals that have units associated with them. You specify the units and parameter values in the block dialog boxes, and Simscape performs the necessary unit-conversion operations when solving a physical network. A Physical Signals block library lets you perform math operations on physical signals, and graphically enter equations inside the physical network. Physical signal ports are used in Simscape block diagrams to better integrate physical signals into your physical system, which increases computational speed. Using the elements contained in these foundation libraries, you can create more complex components that span different physical domains. As with Simulink, you can then group this assembly of blocks into a subsystem and parameterize it to reuse and share these components.
