CAD Related Experience
Over the course of my carreer I have worked with many CAD systems, with exposure to ProE/Wildfire, CATIA V5 and of course, Solidworks, which remains my primary CAD system. In that experience:
- Over 40,000 cumulative hours in Solidworks, in part design for manufacture, and print generation including the use of GD&T methods.
- PDM life cycle establishment and implementation, Various Platforms
- Structural and Fluid simulation using Solidworks Simulation
Starting up with a new concept for an Electric Bike, we started by breaking the mold a bit. A rough CAD rendering below shows the rear powertrain, reserving the body exclusively for battery power and control.
What jumps out, of course is the hub-less concept, eliminating some rotating mass. A series of smaller motors are mounted to the rim, directly driving the wheel. This will increase the unsprung mass, but it is felt it can be compensated for with proper selection of the shock and spring. The hubless concept offers its own unique challenges as well.
Work for DP DJ Stands primarily involved crafting sheet metal patterns, to form an interlocking system which required no fasteners for assembly. Conceptual work included a tension design, which would stabilize upon loading.
This task for Maury Microwave started out relatively small, with the request for a design change of their existing tuner. The project quickly expanded to a full redesign, involving better actuators using closed loop stepper motors, introduction of linear drives and a structural redesign to reduce assembly tolerance stackup.
