How a Rear Differential Works Proof Engineering has created this video to describe how a standard open differential works. All modern cars, whether front or rear wheel drive employ some form of differential. Simply put, the differential allows engine power to be divided among the driving wheels in varying proportions for cornering. |

Finite Element Analysis
Part Handling Simulation A finite element analysis simulation was performed to simulate a part handling process using LS-DYNA. Shown, is a hand-off between a vibrating bowl feeder and plunger which presents the part to a laser marking device. |
Tire Traversing a Ramp Using LS-DYNA, a finite element analysis simulation was performed to simulate a tire traversing a ramp. The pressurized tire and ramp were modeled accurately in order to effectively describe contact pressures. Additionally, stresses were evaluated along all points of the traversed path. |
Airbag Unfolding Simulation A finite element analysis simulation was performed by Proof Engineering to demonstrate LS-DYNA's airbag capability as applied to airplane evacuation slide deployment. This basic model is the foundation for more complex folding configurations. |
Structural Design
Structural Tower Design This video shows the results of a modal analysis used to help determine the stiffness of a tower structure. Solidworks and structural FEA software were used in conjunction to achieve a robust, safe, and lightweight design in a short amount of time. |
Manufacturing Automation
Seam Welding Machine This is a custom seam welding machine designed by Proof Engineering. The machine folds a strip of fabric in half and welds the sides with streams of hot air. In the past, strips were created manually and the process was slow, tedious, and messy. This solution is nearly 10 times quicker and has no residue issues. |
Pneumatic Index Machine This machine was a unique challenge as it had to operate in a harsh environment consisting of abrasives and liquid. The unit consists of rodless cylinder, air motor, and pneumatic indexer. |
