Fillet Everything

Hi, I'm Nicole Martinez and a mechanical engineering graduate! This blog is where I will post all my hobby Solidworks models as a sort of portfolio!

Wrote a simple script in Matlab to plot the paths of the crank, rocker, and the point P.

Then used Solidworks Motion Study to trace the path of an arbitrary point, P, on a coupler link (blue) of a four bar mechanism to check the accuracy of the script.

The script allows you to visualize the paths of any point on a fourbar mechanism given the lengths of all links without having to model anything first.

(This was an example of a Non-Grashof triple-rocker, so Matlab only plotted the path of point P until the crank could no longer fully rotate)

Another example of a piece (not shown) driven via crank-rocker linkage assembly. The motor had a hardstop bracketed to the front to prevent overdrive from the motor and cause the parts to crash and collide. The hardstop paddle went through several iterations to aid in manufacturability.

An assembly demonstrating a piece (not shown) directly driven by a motor via a flanged shaft (with asymmetrical bolt pattern). The asymmetrical bolt pattern ensured the shaft was installed in the correct orientation with respect to the sheet metal piece and a hardstop bracket.

A complex projector casing intended to be 3D-printed. The design intent focused on three parameters:

a. a chamber to vacuum out hot air emitted from the projector

b. a chamber to pump in cool air through a fitted, threaded nozzle

c. a mounting mechanism for a fisheye lens and gimbal that allowed fine-tuned manipulation of the projection

A 3DOF jointed robot that can mimic the motions of a wrist (tilt up/down, tilt left/right, and roll along the central axis)

Used Solidworks Motion Study to make a simple universal joint. The red line represents the (angular) input velocity of the green shaft and the blue line represents the output velocity of the red shaft.

Just a few quick sheet metal designs. I’m moving back to Texas and I haven’t had much time to use Solidworks

Gear coupling assembly with keyed hub. The sleeve is bolted together with M12 bolts. Washers on each end prevent wear of the surfaces.

Some flanged shaft collars and other cast/machined parts

During my Imagineering internship, I learned a lot about 3D sketching to make piping or model wiring.

Speed modeling practice from a workbook and a drinking glass I own.

Back to basics: wrapping sketches and helices onto round surfaces

The spout of the teapot was made using lofts and spline guide curves. :) Very fun.

Chebyshev’s Linkage to produce (somewhat) linear motion from a rotating input. 

I used two equal length linkages with clevis heads which required the connecting linkage (pink) to be curve to produce an offset.

Slider-crank mechanism.

Just a simple test of Solidworks video export feature.
