MECH 8290 - Capstone Project 2

Boat stabilization (anti rocking) system
While on a ship of any size, it is desirable to have a stable deck to ensure maximum safety and enjoyment for passengers. Ships have normally relied upon the design of their hulls for stability. However, even with a superior hull design, ships are incapable of completely mitigating such rolling motion. To reduce rolling motion further, an additional stabilization system must be implemented. This report documents the development of such a stabilization system in response to the request for proposal (RFP) received from WaterWorks Co. on October 17, 2017.
Design and development of a 2-axis servo trainer
Servo motors are complex electro mechanical units that allow their rotational position, velocity, acceleration, and many other aspects to be controlled very accurately. Specialized control modules and programming is required for these motors to exhibit desired behavior. Both factors vary drastically between competing companies such as Bosch Rexroth and Allen Bradly. These motors and drives are used extensively in industrial settings, which are very costly and hazardous settings to learn their functionality. For this reason, Bosch Rexroth develops servo trainers that replicate industrial processes at a desk sized scale to render learning safer and cheaper. This project resulted in the design and manufacturing of a trainer system, which consists of two portable units: The electrical controls (Alpha Prototype), and the emulation of an industrial flying saw (Beta Prototype).
Design and manufacture of an indoor paddleboard trainer
The project commissioned by DOS Watersports requires a development of a functional prototype of an indoor paddle board trainer. Some of the requirements for the paddle board trainer included inertia and variable resistance. The scope of the project was focused solely on the paddle motion and not the user’s ability to balance on the paddle board. The form of resistance was open ended, as well as the budget for the paddle board trainer.
Front-end wheelchair attachment analysis
The objective of this project is to develop a SolidWorks simulation model which reflects the same geometry as a physical model given by the sponsor, furthermore has the capability to conduct accurate static loading simulations. As well an objective is to conduct a static simulation stress study on the foot-peg of the wheelchair to simulate and determine the stresses that are formed by a 200lb load (mimicking a person) on the wheelchair while the front-end attachment is secured onto the foot-peg. To ensure the results gathered from simulations are correct, physical validation conducted using a strain gauge test and an analytical calculation were used to determine the stresses at a specified point. Using the simulation and two validation methods, an acceptable result for the stress at a specified location on the frame can be verified and analyzed. The purpose being to determine if the SolidWorks simulation model results at the same point can be validated by the physical and analytical.
MATE 2018 ROV Competition
Deep Blue Marine Engineering (DBME) has developed an ROV that satisifies the design requirements outlined in the RFP submitted by the Applied Physics Laboratory (APL) at the University of Washington. DBME’s Marauder was designed and built by a team of 4 mechanical engineering students from the British Columbia Institute of Technology (BCIT). Marauder was prototyped to perform tasks required for locating and recovering the engine of a vintage airplane, installing a seismometer, and installing a tidal turbine and instrumentation to monitor its marine environment. Marauder was intially prototyped at BCIT’s Burnaby campus before it underwent thorough and rigirous testing at the BCIT Marine Campus to ensure functionality and reliability when performing the required tasks. To complete the scope of work provided by the APL at the University of Washington, DBME was organized into mechanical and electrical design teams. A collaborative design approach between mechanical and electrical design teams was used to insure functionality and control of mission specific tooling during prototyping and testing. Marauder’s frame and tooling was precision manufactured using in-house equipment that includes a 3-axis CNC mill, a water jet cutter, and multiple 3D printers to insure component fitment and potential development of multiple prototypes. Furthermore, with the aid of precision manufacturing equipment, Marauder’s frame and tooling was also designed to meet the minimal size and weight requirements for ease of portability. The following technical document outlines the design process and results produced by BCIT Deep Blue Marine Engineering during the development and prototyping of Marauder.
Multi source heat pump for geoexchange systems (GXS)
With the use and effectiveness of conventional heat pumps decreasing drastically in colder climate regions, geo-exchange systems have become the solution to allow heat pumps to still be operable in these colder regions. However, with the high costs of installation required for deep-well heat exchangers and horizontal-trench heat exchangers, and the high cost of land in high-density urban/suburban areas, their adoption is still small. For this reason, this project aims to increase the energy density of geo-exchange systems so that high installation costs are not required, and large land requirements become non-existent.
Rexroth Bosch two axis servo trainer
This document is a final report on the fourth-year mechanical engineering Capstone project: Two-Axis Servo Trainer/Bolt Tightener. This report covers the project background, current status, theory, activities, results, and conclusions. The project was sponsored by Rexroth Bosch who provided the opportunity to two BCIT fourth-year mechanical Capstone groups. The project was to create a physical servo motor trainer for learning employees and clients. The mechanism must be based on a commonly automated industry task, require position, velocity, and torque control, and 2-axis synchronization.
Skateboard truck testing device
Skateboard trucks are one of the three major components that, when assembled together, make up a skateboard along with the skateboard deck and wheels. The truck connects the deck to the wheels and translates the tilting motion of the deck to a turning motion of the truck to cause a turning response. As such, there is a relationship between how much the deck tilts to how much the trucks turn. Furthermore, the truck itself can come in varying sizes and configurations. The axle length, hardness of the bushings used and the angle that the truck sits on relative to the deck all can vary to provide a different feel and response for the rider of the skateboard. Although skateboards have been used since the early 1960’s, no device has been created to quantify the feel that skateboard riders feel with varying configurations of the truck. The purpose of this device is to provide quantitative data and results for each truck configuration tested so that the response of differing setups can be compared and provide valuable results for either riders or companies that design skateboard trucks.
Truck bed bike rack
McMillian’s Bike Co. contracted Wix Design Ltd. to design and prototype a bike rack situated in the bed of a truck. After doing a survey of their customers, McMillian’s Bike Co. found that customers were not satisfied with the current products in the market for transporting bicycles and believes there is a unique product development opportunity. The objectives that McMillian’s Bike Co. aim to fulfill is that the product be modular, compact, easy to use/install, versatile, affordable and secure. In terms of compactness the product should be able to hold at least four bikes with the potential of holding up to five. The product should be versatile in terms of securing different types of bikes that can range from BMX bikes to large mountain bikes. The product should be able to be broken down into modular units so that one can choose how many bikes can be attached to the rack. The design team from Wix Design Ltd. set out to design a product that would meet these criteria.
