Senior Design Project

December 2002 Senior Project Presentations

Hydraulic Press Arms

Team 1: Shannon Debelak, Tony Hasenour
Advisor: Dr. Short

Objective: Design a set of arms for a hydraulic press that will ease the setup for the work piece to be pressed.

Description: Design consists of four arms. Two of the arms will be allowed to pivot on a specifically designed mount located on both sides of the press. These mounts are the heart of the design. They will be able to attach to the current press that is located in the EB machine shop. Each of the mounts are able to translate up and down the sides of the press, just as the current “bench” style design is able to do now. The arms pivot via locking pins on the mounts. This pivot design will allow the user to press many different shapes and sizes of work pieces without the use of specialized plates that are needed with the current design.

Torque Sensitive Slip Clutch

Team 2: Matthew Essington, Tony Loiacono, Brigitte Meehan
Advisor: Dr. Short

Objective: To design a clutch that acts as a safety device by slipping after a designated torque is transmitted. This clutch is also semi-adjustable for different slip torques.

Description: This project uses the properties of friction to transmit torque. It uses springs to provide normal force, and two friction plates acting on a single pulley or gear sprocket. The clutch will fit on a motor shaft to prevent motor damage or damage to whatever the sprocket is driving.

Portable Hoisting Mechanism

Team 3: Matthew Gregait, Eric Dams, Holly LeBlang
Advisor: Dr. Short

Objective: To develop a portable lifting device which would hoist 100 pounds of construction material to a height of 30 feet.

Description: Statistics show that a majority of ladder related accidents are due to the user attempting to climb while carrying construction materials. The purpose of this project is to design a lifting device would allow a person to raise construction materials safely to a worksite. This objective has been achieved by first developing a wheeled platform which rides within incremental locking channels. Next the locking mechanism was designed to allow the extending channels to vary in length between 15 and 30 feet. Finally an electric motor was selected and a motor mount was developed to raise the platform.

Pneumatic Table with Individual Lift Tops

Team 4: Anthony Leycock, Charles Matthews
Advisor: Dr. Short
Sponsor: Leath Furniture DeKalb, American Cylinders Peotone IL

Objective: Table is intended to put an individual in a better position for the consumption of food in front of the television.

Description: A standard table has been redesigned with a pneumatic cylinders and a four bar mechanism and other components to extend the table top to a position where a person can eat without having to lean over. This table will be activated with a foot switch to allow hands free operation.

Disclaimer: This table is intended mainly for the lazy. Failure to be lazy might cause this table to work improperly.

Design Consolidation and Cost Reduction of Vactor Model 2 100 Subframe

Team 5: Doug Durdan, Nick Kirichkow, Tina Lake
Advisor: Dr. Short
Sponsor: Vactor Manufacturing

Objective: To reduce production costs by $200k annually (based on annual volume of 400 units) and improve design modularity by consolidating six subframe designs into a single design.

 

Description: Significant rework was required at assembly due to chassis variations interfering with components on the previous design. By redesigning the subframe, the clearance was designed in to accommodate chassis variations and eliminate rework at assembly, which required torching off components, welding them back on in a different location, and then performing paint touch up. Consolidating six previous designs into a single design allows for leaner manufacturing and engineering processes.

Extendable and Retractable Delivery Ramp

Team 6: Jacob Bavirsha
Advisor: Dr. Short

Objective: To create a stable and transportable delivery ramp that can extend to deliver materials down variable stair lengths.

Description: Create detailed Pro-E drawings of individual parts of the assembly, create exploded views of the whole assembly to assist in manufacturing process, perform yield stress analysis on slot sections of the side, perform stress test on Pro-E, manufacture and assemble prototype.

Target SEM Wire Plane Redesign

Team 7: Benjamin Elzeman
Advisor: Dr. Short

Objective: Simplify and streamline assembly of the wire planes in the target SEM.

Description: The way wires are assembled was changed from a crimp-on wire lug that had to be accurately placed before assembly, to a clamp which is tightened during assembly.

Infrared Remote Controlled Indoor TV Antenna

Team 8: Amad Alrousan, Brian Jahr
Advisor: Dr. Short

Objective: The objective of this project is to produce a working prototype of an infrared remote controlled indoor television antenna.

Description: Many indoor television antennas are quite inexpensive, but will only receive one or two channels poorly, and are difficult to tune. Our design is an easy to tune by remote control, can aquire several channels quite well by incorporating a signal amplifier, and would still be affordable.

Four Bar Putter Tester

Team 9: Jason Salisbury
Advisor: Dr. Short

Objective: To recreate the putting swing of a golfer for use of testing putters.

Description: Current putter testers use a simple pendulum to test a putter’s performance. This type of swing motion doesn’t represent the actual way a golfer swings a putter. A putt is typically a longer sweeping motion rather than an arc. To accurately the performance of a putter a more accurate swing is necessary. The four bar linkage can create a sweeping motion that accurately resembles a putt.

Die/Assist Lifting Device

Team 10: Kevin Sanford, Joe Budill, Adam Hervatin
Advisor: Dr. Short
Sponsor: Alloyd Company, DeKalb, IL

Objective: To design and construct a device which safely and efficiently assist in the loading of tools between two vertical presses.

Description: During setup or teardown of a production machine, a tool (die and assist) weighing up to several hundred pounds, must be placed (or removed from) between two vertical presses. These operations have resulted in personnel and equipment damage. To help eliminate these problems a group of three interns developed a system in which the tools are lifted using a bracket and clamp and rolled between the presses.

Significant Impact: This device will result in fewer personnel injuries and reduce damage to the equipment, therefore, saving the company time and money in lost production and man-hours.
