Mechanical Engineering Technology Labs

Mechanical Engineering Technology concentration consists of several labs. The labs are:

Research Lab

Air Curtain Research Lab

Director: Dr. Mazyar Amin

Location: Thesken Hall, Room 10-A

This lab space is dedicated to research on optimization of air curtain performance in different applications. Current projects focus on:

  • Improving energy efficiency of open refrigerated display cases
  • Creating hospital clean bed zone, to avoid bacterial/viral transmission between patient and visitors
    • This is collaborative research project with Nursing Department, as well as Microbiology Department at Miami University

Teaching Labs

Manufacturing Lab

Director: Prof. Rob Speckert

Locations:

Middletown Campus: Thesken Hall, Room 08

Hamilton Campus: Phelps Hall, Room 102

The Manufacturing Laboratories in Engineering Technology provide opportunities for students to demonstrate and apply the concepts of machining (turning, milling, drilling, etc.), computer numerical control (CNC) programming, CAD/CAM, 3D printing, robotics, automation/system integration, and quality control/SPC. Students utilize the lab equipment to manufacture parts and systems for their manufacturing classes, projects for other classes, and senior design projects. Students gain hands-on experience with manual machining, CNC programming, robotics programming, PLC programming and system integration. The main equipment in these labs are:

  • Lathes, mills, drills, cut-off saws, and bench grinders
  • CNC machines
  • 3D printers
  • Robots
  • PLCs
  • Conveyors
  • Various measurement devices
  • Material testing equipment
  • Complete set of hand tools

Measurements Lab

Director: Prof. Gary Drigel

Location: Thesken Hall, Room 11

In the Department of Engineering Technology the Measurements and Instrumentation labs provide students with opportunities to observe, touch and interact with a wide variety measuring devices used in the design and manufacturing world. In designing structures, machinery, mechanisms, transportation systems and mechanical devices, students learn to follow traditional design processes and codes. One of the most important things to do once a design is completed is to measure its performance and compare that performance against predicted and calculated design parameters. In this way designers can insure that their design processes are valid and the predicted performance will be met. This also allows for modification of design parameters to insure accuracy in future designs. 

This laboratory serves the Strength of Materials (ENT 272), Machine Designs (ENT 278), and Fluid Mechanics (ENT 310) Experimentation Techniques for Engineering Technology (ENT 404) and Senior Design (ENT 497/498) courses. The main equipment in this lab are:

  • Thermocouples, Thermistors, Infrared Thermal imaging (IR) systems
  • Potentiometers and Linear Variable Differential Transformer (LVDT) devices
  • Load cells and Strain Gauges
  • Torque Meters and Torque Wrenches
  • Pressure Gauges, Manometers and Pressure Transducers
  • Flow Meters and Velocity Devices

  • Numerous Calibration Devices (gauge blocks, dead weight gauge calibration, etc.)

Thermal-Fluids Lab

Director: Dr. Mazyar Amin

Location: Thesken Hall, Room 10

At the Department of Engineering Technology, Thermal-Fluids Laboratory creates opportunities for its students to demonstrate and apply the concepts of fluid mechanics, applied thermodynamics and heat transfer. Students conduct experimental studies of energy processes and learn data reduction and analysis procedures.

Vibration Lab

Director: Dr. Vipul Ranatunga

Locations: Middletown Campus: Thesken Hall, Room 11

The Mechanical Vibration Lab on the Middletown campus provides hands-on experience with instrumentation used for vibration monitoring and modal analysis. The lab is equipped with a mass-spring-damper system to study the effect of structural stiffness and damping on mechanical vibrations. This system has a sophisticated excitation scheme to simulate various types of vibrations such as periodic sinusoidal vibrations, random vibrations, as well as impact and user-defined vibration signals. During the laboratory exercises, students utilize this setup to understand the free and forced vibrations and the effect of damping on vibration suppression under resonant conditions.

Another exciting laboratory instrument in the mechanical vibration lab is the electro-magnetic vibration shaker and the control system. This system provides hands-on experience with modal analysis. Test objects can be mounted on top of the vibration shaker to study the resonant frequencies and modal shapes.

Mechanical vibration lab is equipped with numerous accelerometers, displacement sensors, velocity transducers, hand-held vibrometers, etc. to provide a comprehensive coverage of instrumentation used in vibration monitoring, control, and isolation. Students taking Topics in Mechanical Vibrations (ENT 416) use this laboratory to acquire the practical experience with instrumentation related to mechanical vibrations.

List of Laboratory Equipment:

  • ECP-310 Mass-Spring-Damper System
  • LDS Electro-Magnetic Vibration Shaker
  • Rotational system instrumented with various vibration measurement sensors to demonstrate the shaft vibration, monitoring, and control
  • Hand-held vibro-meter to measure displacement, velocity, and acceleration
  • Piezoelectric Accelerometers, non-contact type eddy-current displacement sensors, rotary encoders, etc. for vibration measurement
