8:00 am - 12:00 pm
C11 Basic Lubrication presented by Dr. Robert M. Gresham, STLE Director of Professional Development

This course is primarily designed for the beginner looking for basic concepts related to friction, lubrication and wear. Additionally, this course will cover the basics of lubricant maintenance through Oil Analysis. The course is divided into four parts beginning with friction. In this part, concepts leading to an understanding of the First, Second and Third laws of Friction are covered. In addition, the concepts behind static, dynamic and stick-slip friction are discussed. Finally, the Adhesion Theory of Friction which leads to an understanding of wear processes is covered. The second part, Lubrication, covers the Lubrication Regimes: Boundary, Elastohydrodynamic, Hydrodynamic, & Mixed. These regimes describe the lubrication processes from very small relative motion to much higher speeds and include the special considerations related to anti-friction bearings, such as ball bearings. The Wear segment covers the twelve types of wear that can be encountered in machinery including Hydraulic systems. Finally, the course will cover the basics of maintenance of lubricants, including hydraulic fluids through Oil Analysis. The segment covers the business drivers for an oil analysis program, key test methods and steps for implementation of a program.

C12 Hydraulic Fluids and their Application presented by Mr. David K. Scheetz, Lubrication Equipment Builder Engineer, ExxonMobil

This course is designed primarily for users of hydraulic equipment who have a basic understanding of lubrication theory and who are looking to learn more about the hydraulic fluids utilized in hydraulic systems. The course is divided into two parts. The first segment covers the basics of hydraulic fluid composition and function. This segment will also cover fluid maintenance issues specific to hydraulic fluids. The Second segment, covers a number of hydraulic applications and the process for selecting and specifying the proper hydraulic fluid for that application.

C21 Noise in Hydraulic Fluid Power Systems presented by Dr Nigel Johnston, Department of Mechanical Engineering, University of Bath, England

One reality of hydraulic fluid power systems is that they can be extremely noisy. This is perhaps a natural consequence of their high power density. It can limit the range of applications of hydraulics, and often causes the system designer to favor other means of power transmission. A particular issue with hydraulic systems is fluid-borne noise. This takes the form of pressure and flow pulsations in the hydraulic fluid. Unfortunately hydraulic fluid is a very efficient medium for transmitting noise. This course provides a description of the mechanisms by which fluid-borne noise is generated and transmitted. Experimental methods for measuring the fluid-borne noise characteristics of pumps and other components are described, methods for reducing noise are outlined, and methods for predicting the fluid-borne noise characteristics of hydraulic circuits are explained.

Program outline:

• An introduction to noise in hydraulic fluid power systems
• Pump flow ripple
• Transmission of fluid-borne noise
• Noise Reduction and Control
• Measurement of fluid-borne noise and rating of pump noise

C22 Design, Modeling and Control of Hybrid Vehicles presented by Zongxuan Sun, Department of Mechanical Engineering, University of Minnesota

With the rising oil demand and concerns on climate change, improving fuel efficiency and reducing emissions has become the main target for automotive powertrain research. Powertrain hybridization has been widely accepted as one of the most promising solutions for addressing this issue. In a hybrid vehicle, an alternative power source (electric power or fluid power, for example) complements the internal combustion engine, to improve fuel efficiency by engine downsizing, load leveling, and regenerative braking. This short course will cover the background information, the various types of hybrid vehicles, the architecture of hybrid powertrain, and the modeling and control the hybrid vehicle.

Admission for each course is $300 in advance and $310 onsite.
If registering for more than one course, admission is $225 in advance and $235 onsite.

Upon completion of these courses, Continuing Education Units (CEUs) are available at no additional fee.
