Internship Volvo Group

January 2020 to June 2020

I worked full time as a mechanical engineer intern for the pneumatics division. Where I experienced, learned, and grew in a variety of areas. I digitally routed the pneumatics lines on full truck assemblies, specified and tested COTS fittings, designed new product variant, conducted diagnostic testing, self taught programing in Python creating a GUI, and created instruction drawings for Covid-19 ventilators by MIT with Volvo Group parts.

CAD routing of Pneumatic lines

I worked on large assemblies, routing pneumatic lines using PTC Creo 5.0.

I worked on adding a complete pneumatic line [red] for the testing and development of auto leveling mechanism and sensing, from the electronic button inside the cabin interior to the end pneumatics connectors. Also I routed the electrical wiring that supports this new system [blue].

New pneumatic connectors: by Knogsberg

I supported a senior engineer in the documentation and instruction specifying new pneumatic connectors by Knogsberg.

Also I tested and determine the torque necessary for the new fittings to operate and also prevent air leaks.

New POGO stick backet

I work on designing a new pogo stick bracket variant. The new design used a clamping fasteners rather than the previous bolts and nuts.

The previous bolt nuts was constrained by the chassis bolt pattern limiting the placement of the pneumatic bracket and sometime leading to interference issue in the factory.

As result I create a bracket design that was independent of the chassis' hard bolt patterns, giving the pneumatic bracket more range and flexible of placement.

I create the engineering drawing and fabricated the part and test the part on a truck for fitment.

Pneumatics Hands on testing

I worked hands on to conduct diagnostic pneumatic leak test. Researching and collecting data points to conclude a analyses result.

Attaching a prototype diagnostic tool, I test over 80 trucks' pneumatics system for air leaks. Through the OBD2 port I run developing software and held open discussion and feedback of its usability.

I collected all the data into an comparison chart, and presented to division leadership. I then collected 50 data points remotely data from the trucks gps data collection and highlighted possible points of interest.

GUI Development Python, Matlab, Excel

I was self taught and learned python on the fly. I coded a custom GUI using python. This GUI is independent to a similar MATLAB code but frees the company from expensive licensing ties of MATLAB. The application creates simulation of configuration to show the user buildable and non-buildable variants.

The GUI selects four independent variables from multiple sheets from an excel data set. The GUI tells the user live feedback of plausible and non-plausible configurations for the pogo stick by embed calculations of truck cabin length, rear axle position, hose length, and fifth wheel placement. The GUI also includes a graphic illustration that updates automatically. It also does quick calculation giving the user clear measurements in mm and feedback with colors green, red, and yellow.

Installation document drawing corrections

I worked on PDF documents that guides the assemblers during installation of truck configurations. I supported the screenshot and numbered the balloons and release the document using an in-house PDF formatting.

Covid-19 response

I created instruction manual for a ventilation system by MIT with parts retro fitted with Volvo parts as a response to the covid-19 situation in 2020.

I modelled the assembly, and created all exploded views of all images in the document. I added all hardware. Volvo used the instructions manual to support rapid ventilator production.
