1. To create toe and camber variables:
1) From the Build menu, point to Suspension Parameters, point to Toe/Camber Values, and then select Set.
2) Fill in the dialog box as shown next, and then select OK.
8.2.9 Creating the Hub
Before you create the hub part for your template, you must create a construction frame. Construction frames are ADAMS/Car elements that you use whenever an entity requires that you specify an orientation in addition to a location.
You create the hub based on the construction frame, and then create geometry for the hub.
1. To create a construction frame:
1) From the Build menu, point to Construction Frame, and then select New.
2) Create a construction frame as follows:
Construction Frame: hub_bearing
Coordinate Reference: ._macpherson.ground.hpl_wheel_center
Orientation Dependency: Toe/Camber
Toe Parameter Variable: ._macpherson.pvl_toe_angle
Camber Parameter Variable: ._macpherson.pvl_camber_angle
3) Select OK.
2. To create the hub part:
1) From the Build menu, point to Parts, point to General Part, and then select New.
2) Create the hub part as follows:
General Part: hub
Location Dependency: Delta location from coordinate
Coordinate Reference: cfl_hub_bearing
Location values: 0, 0, 0
Orientation Dependency: Delta orientation from coordinate
Construction Frame: cfl_hub_bearing
Orientation: 0, 0, 0
Mass/Ixx/Iyy/Izz: 1
3) Select OK.
3. To create cylinder geometry for the hub:
1) From the Build menu, point to Geometry, point to Cylinder, and then select New.
2) Create the cylinder geometry as follows:
Cylinder Name: hub
General Part: ._macpherson.gel_hub
Construction Frame: ._macpherson.ground.cfl_hub_bearing
Radius: 30
Length in Positive Z: 30
Length in Negative Z: 0
Color: magenta
3) Select Calculate Mass Properties of General Part.
4) Select OK.
The template now includes the hub.
8.2.10 Creating and Defining Attachments and Parameters
Now that you created all the ADAMS/Car parts, springs, and dampers, you are ready to define attachments and parameters.
1. Defining the Translational Joint
1) From the Build menu, point to Attachments, point to Joint, and then select New.
2) Create the translational joint as follows:
Joint Name: strut_joint
I Part: ._macpherson.gel_wheel_carrier
J Part: ._macpherson.gel_strut
Joint Type: translational
Coordinate Reference: ._macpherson.ground.hpl_strut_upper
Orientation Dependency: Orient axis along line
Coordinate Reference #1: ._macpherson.ground.hpl_strut_lower
Coordinate Reference #2: ._macpherson.ground.hpl_strut_upper
3) Select OK.
2. Defining Control Arm Attachments
To create the mount parts:
1) From the Build menu, point to Parts, point to Mount, and then select New.
2) In the Mount Name text box, enter subframe_to_body.
3) In the Coordinate Reference text box, enter ._macpherson.ground.hpl_arm_front.
4) Verify that From Minor Role is set to inherit.
5) Select OK.
ADAMS/Car creates fixed joints between the mount parts and ground. By default, the visibility of the fixed joints is turned off.
To create the front bushing for the control arm:
1) From the Build menu, point to Attachments, point to Bushing, and then select New.
2) Fill in the dialog box as shown in figure 8.4, and then select Apply.
To create the control arm revolute joint:
1) Create the control arm revolute joint as follows:
Joint Name: arm_front
I Part: ._macpherson.gel_control_arm
J Part: ._macpherson.mtl_subframe_to_body
Joint Type: revolute
Active: kinematic mode
Coordinate Reference: ._macpherson.ground.hpl_arm_front
Orientation Dependency: Orient axis along line
Coordinate Reference #1: ._macpherson.ground.hpl_arm_front
Coordinate Reference #2: ._macpherson.ground.hpl_arm_rear
2) Select Apply.
To create the control arm spherical joint:
1) Create the control arm spherical joint as follows:
Joint Name: arm_outer
I Part: ._macpherson.gel_wheel_carrier
J Part: ._macpherson.gel_control_arm
Joint Type: spherical
Active: always
Coordinate Reference: ._macpherson.ground.hpl_arm_outer
2) Select OK.
