MECT 2911 - Mobile Hydraulics Technology

Credit Hours: 3.00
(4 contact hrs)
This course teaches the fundamentals of Mobile hydraulic systems including components, graphics symbols and basic circuit configurations. Students will perform calculations for actuator area in square inches, extensions and retraction forces in pounds, pressures in pounds per square inch, and speeds in inches per minute. Students will draw and simulate mobile hydraulic circuits using Automation Studio then connect the circuit on a functional hydraulic trainer.

Prerequisites:
None

OUTCOMES AND OBJECTIVES
Outcome 1: Upon completion of this course, students will be able to explain the principles of mobile hydraulics and determine the operating characteristics of a mobile hydraulic system based on parameters given.

Objectives:

Calculate the areas, volumes, force, velocity and pressures associated with hydraulic cylinders.
Explain Pascal’s law, Bernoulli’s principle and the principles of atmospheric and head pressure.
Explain the operation of mobile pumps, directional controls, pressure controls and flow controls.
Describe the different properties of hydraulic fluids and create a contamination control program.

Outcome 2: Upon completion of this course, students will be able to determine the operating characteristics of a hydraulic system based on parameters given.

Objectives:

Calculate cap end, rod end and rod areas as well as area ratio for a cylinder.
Calculate the maximum force of a cylinder or torque of a motor.
Calculate the extension or retraction velocity of a cylinder or motor.
Calculate the input and output horsepower for a hydraulic system.

Outcome 3: Upon completion of this course, students will be able to select the appropriate components to provide the mobile functions of steering, propel, and multi-circuit directional control

Objectives:

Calculate the size of a hydrostatic transmission for a propel circuit based on given requirements.
Select the appropriate type of steering control unit from given performance requirements.
Determine the type of direction control needed to provide pressure compensation and flow sharing.

Outcome 4: Upon completion of this course, students will be able to recognize the graphic symbols used to create a Mobile Hydraulic circuit and to draw these using circuit drawing/simulation software and then build the circuit on a hydraulic simulator.
