Rider

The Rider models the mass and inertia of a human body and includes graphics for the human body.

The Rider includes controls for setting the mass and dimension of a human body and for changing the angles in key joints like the knee and hip. Changing the angles in joints allows you to position the rider in many postures like standing, kneeling, or sitting.

The Rider is not flexible: the bodies comprising the model and the joints connecting the bodies are rigid.


Figure 1.

The mass and dimensions of the Rider can be varied based on the modeling requirements.

Add an Rider to a Model

The following steps outline how to add an Rider to the model:
  1. Right-click on the Model in the Project Browser and click Add Auto Entity.


    Figure 2.
    The Add Auto Entity dialog is displayed.

Adjust the Rider Mass and Dimensions



Figure 7.
Parameter Description
Height Input for the Rider height. Height can only vary from 100 – 200 cm. You can use the slider to vary the height.
Body Density Input for Rider body density. Body density can only vary from 500 – 1500 kg per meter cube. You can use the slider to vary the body density.
Mass The mass of the Rider based on the height and body density value. Unit is the same as model units.
Ixx, Iyy, Izz The moment inertia values of the Rider based on the height and body density value. Unit is the same as model units.
Inertia Reference The reference frame that is being used to calculate mass and inertia values.
Set Position Set the pre-defined default positions of the Rider. Current options are: Standing or Sitting.
