brim.bicycle.front_frames.SuspensionRigidFrontFrameMoore

class brim.bicycle.front_frames.SuspensionRigidFrontFrameMoore(name: str)

Bases: SuspensionRigidFrontFrame

Front frame with suspension and no structural flexibility.

Explanation

The front frame is modeled as a rigid body with a suspension. The suspension is modeled as a spring-damper system. The forces are applied parallel to the steer axis with at a parametrized distance symbols["d9"] from the steer axis.

Attributes

auxiliary_handler	Auxiliary data handler of the model.
body	Rigid body representing the front frame.
connections	Submodels out of which this model exists.
convention
descriptions	Descriptions of the attributes of the front frame.
left_hand_grip	Attachment representing the left hand grip.
load_groups	Load groups of the connection.
name	Name of the object.
required_connections
required_models
right_hand_grip	Attachment representing the right hand grip.
steer_hub	Steer axis expressed in the front frame.
submodels	Submodels out of which this model exists.
suspension_lowers	Point representing the suspension slider, where the force is applied.
suspension_stanchions	Point representing the suspension stanchions, where the force is applied.
system	System object used to store the information of the model itself.
wheel_hub	Wheel axis expressed in the front frame.

Methods

__init__	Create a new instance of the model.
add_load_groups	Add load groups to the connection.
define_all	Define all aspects of the model.
define_connections	Define the submodels used by connections in the model.
define_constraints	Define the constraints on the model.
define_kinematics	Establish the kinematics of the objects belonging to the model.
define_loads	Define the loads that are acting upon the model.
define_objects	Initialize the objects belonging to the model.
from_convention	Create a model from a convention.
get_all_symbols	Get all declared symbols of a model.
get_description	Get description of a given object.
get_param_values	Get the parameter values of the front frame.
set_plot_objects	Set the symmeplot plot objects.
to_system	Export the model to a single system instance.

__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 body: RigidBody

Rigid body representing the front frame.

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

Submodels out of which this model exists.

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 front frame.

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

Create a model from a convention.

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 the parameter values of the front frame.

property left_hand_grip: Attachment

Attachment representing the left hand grip.

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

Load groups of the connection.

property name: str

Name of the object.

property right_hand_grip: Attachment

Attachment representing the right hand grip.

set_plot_objects(plot_object: PlotModel) → None

Set the symmeplot plot objects.

property steer_hub: Hub

Steer axis expressed in the front frame.

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

Submodels out of which this model exists.

property suspension_lowers: Point

Point representing the suspension slider, where the force is applied.

property suspension_stanchions: Point

Point representing the suspension stanchions, where the force is applied.

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.

property wheel_hub: Hub

Wheel axis expressed in the front frame.
