__init__(name: str) → None

Create a new instance of the model.

Parameters:

name (str) – Name of the model.

__new__(**kwargs)

__repr__() → str

Return repr(self).

__str__() → str

Return str(self).

__weakref__

list of weak references to the object (if defined)

add_load_groups(*load_groups: LoadGroupBase) → None

Add load groups to the connection.

property auxiliary_handler: AuxiliaryDataHandler | None

Auxiliary data handler of the model.

property connections: tuple[brim.core.base_classes.ConnectionBase]

Submodels out of which this model exists.

property cranks: CranksBase

Submodel of the cranks.

define_all() → None

Define all aspects of the model.

define_connections() → None

Define the submodels used by connections in the model.

define_constraints() → None

Define the constraints on the model.

define_kinematics() → None

Establish the kinematics of the objects belonging to the model.

define_loads() → None

Define the loads that are acting upon the model.

define_objects() → None

Initialize the objects belonging to the model.

property descriptions: dict[Any, str]

Descriptions of the attributes of the object.

classmethod from_convention(convention: str, name: str, *args, **kwargs) → ModelBase

Create a model from a convention.

property front_frame: FrontFrameBase

Submodel of the front frame.

property front_tire: TireBase

Tire model for the front wheel.

property front_wheel: WheelBase

Submodel of the front wheel.

get_all_symbols() → set[sympy.core.basic.Basic]

Get all declared symbols of a model.

get_description(obj: Any) → str

Get description of a given object.

get_param_values(bicycle_parameters: Bicycle) → dict[Symbol, float]

Get a parameters mapping of a model based on a bicycle parameters object.

property ground: GroundBase

Submodel of the ground.

property load_groups: tuple[brim.core.base_classes.LoadGroupBase]

Load groups of the connection.

property name: str

Name of the object.

property rear_frame: RearFrameBase

Submodel of the rear frame.

property rear_tire: TireBase

Tire model for the rear wheel.

property rear_wheel: WheelBase

Submodel of the rear wheel.

set_plot_objects(plot_object: MplPlotBase) → None

Set the symmeplot plot objects.

property submodels: tuple[brim.core.base_classes.ModelBase]

Submodels out of which this model exists.

property system: System | None

System object used to store the information of the model itself.

Notes

This system object is used to store the information of the model itself. It does not by definition contain any information about the submodels or connections. Therefore, one cannot use this system object to form the equations of motion. Instead, one should use the to_system() method to get the system object representing the entire model.

to_system() → System

Export the model to a single system instance.
