Chassis Visualization Example

This example demonstrates how to use the pyMyCar package to create and visualize different car chassis models. The chassis is the main structural component of a vehicle, supporting the body and other parts.

The code below shows how to: - Import and use predefined chassis models from pyMyCar. - Visualize these models in 3D with PyVista, including the reference coordinate axes. - Compare different chassis designs by rendering them in separate windows.

Import necessary libraries

import numpy as np
import pandas as pd
import pyvista as pv

Import from pymycar package

from pymycar.Cad.Chassis import formula, tourist

Formula

Model A

chassis_formula_A = formula.model_A(front_axle_to_com=1500,
            rear_axle_to_com=1645*0.5,
            front_track=1500*0.5,
            rear_track=1645*0.5,
            com_height=400.0,
            roll=0,
            pitch=0,
            yaw=0,
            x=0,
            y=0,
            z=0)

Define the specific point location for the reference coordinate system

reference_point = np.array([0, 0, 400])

plotter = pv.Plotter()
plotter.add_mesh(chassis_formula_A, color="red", opacity=0.5)

axes = pv.Axes()
axes.axes_actor.z_axis_shaft_properties.color = (0.0, 1.0, 1.0)
axes.axes_actor.shaft_type = axes.axes_actor.ShaftType.CYLINDER
plotter.add_actor(axes.axes_actor)

plotter.show()

Model B

chassis_formula_B = formula.model_B()

plotter = pv.Plotter()
plotter.add_mesh(chassis_formula_B, color="red", opacity=0.5)
plotter.add_actor(axes.axes_actor)

plotter.show()

Tourist

chassis_tourist_A = tourist.model_A()

plotter = pv.Plotter()
plotter.add_mesh(chassis_tourist_A, color="red", opacity=0.5)
plotter.add_actor(axes.axes_actor)

plotter.show()
