VFT2010 Basic Vibration Fundamentals Training

The Vibration Fundamentals Training System (VFT) is an integrated educational package for teaching/learning the fundamental principles of mechanical vibration as well as engineering mechanics. It provides both a comprehensive hands-on experimental device and an instrumentation package to enhance student understanding of vibration theory. Students can perform virtual experiments using the vibration simulation software and then verify the results with actual experiments thereby reinforcing the learning of difficult principles.

MFS2010 Basic Machinery Fault Simulator System

Learning Machinery Diagnosis Capabilities

To gain an in-depth understanding of different vibration signatures, controlled experiments on a device that emulates real world machinery are needed. While analysis of a single machinery fault may be beneficial, there are many occasions when the analysis of the interaction between dynamic stiffness, resonance, and speed is essential in order to gain an understanding of real world vibration spectra. With the MFS, the expertise required to diagnose industrial machinery problems in well controlled experiments can be developed and enhanced. Applying this to a real-world situation, a plant running at full production, it is virtually impractical to gain an understanding of the kinetics and dynamics of machinery without adversely affecting production and profits: The MFS enables offline training and experimentation which in turn would minimize production downtime.

Internal Combustion Engine Simulator

The Internal Combustion Engine Simulator (ICES) is designed to demonstrate the operating principles of a typical internal combustion engine. The ICES includes realistic pistons, connecting rod, cams, crankshaft, timing belt, timing of input/exhaust valves, bearings, and the engine block similar to a typical IC engine. The device also includes a flywheel and a planetary gearbox for studying power transmission system. The bench-top system has a spacious modular design featuring versatility, operational simplicity, and robustness.

Tool for Learning IC Engine Mechanism

To gain an in-depth understanding of different mechanisms inside the IC engine and transmission system, it is crucial to perform controlled experiments on a device that emulates real world IC engine. While demonstration of an IC engine mechanism is very beneficial for students, there are many occasions when the analysis of various configurations in the mechanism is essential in order to gain an understanding of kinematics principles used in IC engines.
