Training / Education Classroom Seminars
This seminar is designed to provide gear novices with a general understanding of gear nomenclature, geometry, and arrangements. Starting with the basic definition of gears, conjugate motion and the "Laws of Gearing", you will gain a solid understanding of gearing and the fundamentals of rotary motion transfer through gear-trains. Gear classifications, tooth forms and geometry, and very high-level application considerations, manufacturing processes, and inspection techniques will be covered. Attendees will receive a copy of the book, Gear Design Simplified, by Franklin D. Jones & Henry H. Ryffel.

It has been required recently that diesel engines for passenger cars meet various requirements, such as low noise, low fuel consumption, high power and strict emission limits. The key to decrease the noise is to reduce a combustion noise known as “Diesel knock”. Conventional approaches to reduce the diesel knock are decreasing combustion excitation force due to pilot/pre fuel injection, adding ribs to engine blocks or improving noise transfer characteristics by using insulation covers. However, these approaches have negative effects, such as deterioration in fuel economy and increase in cost/weight. Therefore, modification of engine structures is required to reduce it. We analyzed noise transfer paths from a piston, a con rod, a crank shaft to an engine block and vibration behavior during engine operation experimentally, and identified that piston resonance was a noise source.

High viscosity of vegetable oil causes problems while using them as alternate fuel for compression ignition engines. There is a need to reduce the viscosity before using them as engine fuel. Preheating and pre-treating of vegetable oils using waste heat of exhaust gases is one of the techniques, which reduces the viscosity and makes it possible to use as alternate fuel for some niche applications, without major modifications in the engine hardware. There are several applications in developing countries such as decentralised power generation, agricultural engines, and water pumping engines, where vegetable oils can play a significant role as an alternate fuel. In present investigations, performance, combustion, emission characteristics of an engine using preheated Jatropha oil (J100) and 20% blend of Jatropha oil with mineral diesel (J20) have been evaluated at a constant speed (1500 rpm) in a single cylinder four stroke direct injection diesel engine.

Increasing challenges on reducing fuel consumption has opened the new directions in Automobile Powertrain technologies. The example of such technology implemented in geared transmission is the usage of novel type of gears with 3D point system of mesh engaging invented, patented and developed by Alexei P. Popov. The paper identifies the milestones of R&D that were undertaken to create the new type of geared transmission which could be used in vehicles. Using the Winkler hypothesis Alexei P. Popov had developed and designed new type of point contact which made possible to lower a contact stresses significantly in comparison to the values of a contact stresses for teeth having linear contacting interaction. The new profile and shape of tooth was invented and the methodological tools were developed for engineers providing the formulas for design and forming geometry of tooth with high stress capacity.

Vehicle integration in today society and especially in urban zones is the one of the main focus of regulators as well as car manufacturers. Indeed, vehicles impact on everyday life as air quality, noise, traffic density, urban spaces occupied by parked cars, among others is scrutinized and leads to at least significant efforts, but often to major improvements on all those topics. Noise is one of the key nuisances from which the car is the source. There are already some existing regulations, and they intend to become stricter and stricter. The perfect example of this trend is the recent new European Commission regulation adopted in April 2014, which requires a fair reduction of the allowable emitted noise, but may also introduce performance labels. Of course, there are solutions to deal with noise emissions.

For multi plate wet clutches in transmission systems, an understanding of the dynamic frictional characteristics of the friction surfaces and damping characteristics of the drivetrain are essential in predicting self-excited vibration. We made a test apparatus for torque transmission characteristics and measured the dynamic frictional characteristics of the friction surfaces at a uniform contact pressure. An understanding was gained of the changes in dynamic frictional characteristics due to temperature and contact pressure relating to the sliding velocity. We also obtained the damping characteristics by measuring the torque loss due to drivetrain friction. We created a clutch FEM model to gain a quantitative understanding of how to implement the dynamic frictional characteristics. Taking the damping characteristics of the drivetrain into consideration, we also made a plant model encompassing all areas from the transmission to the vehicle body.

An innovative low cost active gear-shift and clutch for Formula Student cars is designed and produced. Racecars require extremely quick gear-shifts and every system to be as light as possible. The proposed solution has been designed to reduce energy consumption, weight and improve gear-shift precision compared to an electro-hydraulic solution although keeping state of the art performances. This could be easily obtained with DC electric motors, System modeling, regulator design, based on PI-control, and simulation were carried out. Electronics, both signal and power, micro-controller based design and program coding, written in C language, were the next steps. Data from the working system mounted on the car were acquired, in order to verify the validity of the design choices. The solution has proven to satisfy the requirements with 20 ms shifting time and reduced weight (2 kg), energy consumption and system complexity.
