This research project attempts to tackle the major issues experienced with crankshaft vibration in modern internal combustion engines through the use of tuned finite element model and optimized rubber dampers. The purpose of this project is to lay out a systematic approach for the design of torsional vibration dampers when given a set of engine parameters. Current industry development relies heavily on the trial and error method as well as past engineering experience.
Electron beam welding of shroud in Inconel-713LC blades are often associated with cracking. This leads to a high scrap rate for manufacturing of blades used in the gas turbine engines. In this study, in order to understand the root cause of the cracks, a comprehensive experimental and finite element analysis will be carried out to correlate the process variables and response of material to electron beam welding. In that way, electron beam welding process parameters will be optimized to suppress cracking.
Amidst various causes of car accidents, those which result due to unseen vehicles or objects play an important role. Automatic Blind spot detection system is, therefore, one of the solutions which can improve the safety feature of a vehicle. Moovee Innovations, Inc., our partner company, is developing a light-weight vehicle designed to travel at urban speeds, under the name project Insecta. It needs an automatic blind spot detection system as part of their Advanced Driver Assistance System (ADAS) that is capable of warning the driver of hazardous road situations.
The scope of this project is to model and analyze inertial filters used by combustion engines to facilitate exhaust gas recirculation acting as coarse filtration units. This would help to reduce environmental pollution caused by heavy duty diesel engines. By using Finite Element Analysis model to investigate, the design will incorporate the best ratio among the geometric parameters which will enable the least pressure drop for stipulated flow rate. Lower the pressure drop higher will be the fuel savings.
Interest in Arctic shipping is growing as sea ice is melting and as other industries are developing. An increase in shipping presents risks to both the natural environment (from the movement of ships and the products that they carry) and to the local communities that rely on those healthy environments for food and other products. However, the local Inuit people in Nunavut also hold a certain body of knowledge referred to as Inuit Qaujimajatuqangit (IQ).
Aerial spraying (from an aircraft or helicopter) is a crucial component in the management of forest and agricultural lands around the world. Regulatory agencies, government laboratories, and industry have a considerable interest in optimizing the effectiveness of aerial spraying. To deliver aerial spray products with accuracy to their intended target on the ground requires understanding numerous influences primary among them meteorological effects, complex air flows in the wake of the spray aircraft and gravitational effects.
Microsys is a Mississauga company that designs and sells specialized test equipment to airbag manufacturers worldwide. The Cold Gas Inflation System (CGS) allows these manufacturers to test the inflation characteristics of airbag systems in a simple, safe, and inexpensive manner. The CGS involves the rapid discharge of a compressed gas, which the company would like to better understand, in order to further develop this system.
There is a need for customers to use a simple test method to determine if the fuel blends they are using are of the proper composition for fuel efficiency, environment- friendliness and engine cylinder compatibility. But it is difficult to determine the composition of oil/fuel/ethanol mixtures without detailed and expensive chemical analysis. It is because the different hydrocarbons in oils or in fuels are hard to differentiate by physical change or by simple chemical reactions such as pH change.
Composite structures are vulnerable to impact damage, and have to satisfy certification procedures for high velocity impact from bird strike and foreign object damage. Since performing full scale impact tests is highly expensive and thus impractical, the development of validated analytical tools for the prediction of the structural response is essential for the industry to reduce development costs and to speed up the development process.
The proposed project is an extension of an ongoing project with American Bureau of Shipping (ABS), which aims to develop a performance-based winterization guideline for assets operating in harsh environments. The project has led to a novel approach of assessing need of winterization and evaluating extent of winterization required to maintain assets in safe operating condition. The main objective of the proposed project is to further validate the developed approach through a real-world case, i.e., winterization of a ferry operating in offshore Newfoundland and Labrador.
