DRAW

For the assignment of this week I have decided to learn Rhinoceros starting from scratch. I have been practicing, form easy designs like these ones

to these more complicated ones.

Finally, I have developed two possible designs for the earthquake table. For the first one, I have used two motors to move it in two directions while for the second one I have used just one motor limiting the movement to one direction. 

I have been modeling just the design of the earthquake table; it does not include the sensors and connections to the computer, that will transmit and received the data once I finished the project.

Earthquake table A (two motors):

First of all, I have organized the drawing using layers (one layer for each element). Then I started drawing the base of the table, that support a wood frame. Above this base, I have located metallic bearings (3 cm. diameter).

The biaxial earthquake table consists of an aluminium plate (1 x 1 m.) which by its low weight facilitates movement, mounted on metal bearings surrounded by a metal structure that contains it. Aluminum plate is displaced horizontally in two directions by two electric motors controlled by a variable speed drive.

Earthquake table B (one motor).

I started creating a base with four wood pieces (5x12 cm.). Above all of them, I have located another table where I arranged the rails. Then I draw the main table (60x60 cm) that moves in just one direction. Some hooks are used to limit the movement connected to a motor that is responsible for the movement.

ANIMATE

I have also been practicing with SketchUp to develop some basic animations. I have used the Sketchyphysics plugin to make the animations in SketchUp and Camtasia Studio to record and edit the videos. I will continue practicing these tools in the coming weeks.

TEAM ASSIGNMENT

Once I have developed the design, I work with another fab lab student, Covadonga Lorenzo, to create some pictures of the earthquake table using Rhinoceros VRay and some drawings to recreate the final project design. To that end, we scale the models to insert them in the proper scale inside the earthquake Rhino files. Then we use different views to visualize all the faces of the  design and VRay to render some images. Below you can find the results of the cad model for two different tables.

A. One motor table with an architectural model.

B. Two motor table with an architectural model. 

We will decide which table is more appropriate for the test of the architectural models as go along.
