ASSEMBLY OF THE UNDERAGRRIAGE

We have seen how parts can be designed in context, and all the discrete parts making up the final assembly can be made in this manner. However to ensure the design animates, it is necessary to add constraints to each component to correctly predict the behaviour of the whole design.

Begin a new design and select the Frontal Workplane by right clicking and selecting a new sketch, accept the default name of

Sketch 1. Open the Assembly Menu and select Add Component, add each component in turn starting with Wheel 1.des (remember to add stick2.des twice) Fig. 11

Each component can be moved independently of the others by clicking the Select Parts button, clicking the part and moving it. Fig. 12 opposite is the result of such an action.

Select right view to look directly onto the edge of the wheel and tyre.

The two parts will not be aligned depending on how you moved all the parts in the previous activity.

 

 

 

To mate the two parts, select two corresponding faces as shown Fig. 13 From the Assembly menu select Centre Axes. This will align the centre lines of the wheel and tyre. To mate them, select two corresponding faces again and select Mate from the Assembly menu. The two parts will then be aligned and joined.
