Course Syllabus
Fall Semester 2009

 

 

Course Description

 

A study of morphology, operational characteristics, and design considerations of off-road vehicles used in the agriculture and construction.   This course provides an introduction to conceptualization, analysis and design of these vehicles.  Topics to be addressed include: engine performance and design, vehicle testing, turbo chargers and intercoolers, drivetrains, chassis mechanics, electronic systems, hydraulic systems, and human factors.

 

Course Rationale

 

This course is designed to foster creativity; develop within students the ability and confidence to conceptualize and synthesize new off-road vehicles for the agricultural, forestry and construction industries.  Students will be guided in a variety of classroom and laboratory activities in support of developing the necessary analytical and design skills.  Such activities will include functional and design analysis of vehicle sub-systems, and development of new components.  Students enrolled in this course should have completed courses in dynamics, machine design, fluid mechanics and fluid power.

 

Course Objectives

 

On completion of this course students will: 1) appreciate and understand the history of the development and  morphology of off-road vehicles, 2) understand and appreciate the inter-relationships of various vehicle sub-systems, 3) be able to select and integrate current IC engines into modern vehicle designs, 4) analyze and predict the overall performance of power drivetrains, 5) be able to design machine/operator interfaces, and 6) appreciate and understand the role of electronics in control in off-road equipment.

Assignments

 

All assignments are to be submitted through electronic prepared media (i.e., Word, Excel, MatLab, etc.) or handwritten on green engineering paper (National Form #42-381*).   Handwritten assignments and sketches must be clear, concise and legible.  Failure to submit neatly organized assignments will result in minimal partial credit, or no credit at all.  Late assignments will not be tolerated. You are expected to hand in homework assignments and lab reports on the assigned date.  Failure to do so will result in a score of zero.

 

Examinations

 

All examinations will be comprehensive in nature. You will be expected to complete the exam in the allotted time period. Portions of each exam may be either closed or open book. You will be notified of the exam format at least one week in advance.

 

Graduate Student Requirements

 

In addition to all regular assignments and exams, graduate students enrolled in this class will be required to complete a special project.  The basis of the special project will be development of a laboratory investigation in suitable for demonstrating any of the principles covered in class.  The instructor will meet with graduate students to discuss the scope and submission requirements for the special project.  The special assignment must be completed and submitted prior to the beginning of the final exams.
