Ground Vehicle Systems Engineering: A Practical Approach
Duration: 3 Days
Competitive pressures are demanding vehicle designs that better satisfy customer wants and needs over the entire vehicle life cycle and, especially, are less expensive to build and operate. This can only be accomplished by understanding the translation of customer wants and needs to engineering requirements and then ensuring every vehicle produced conforms to these requirements for its entire life, even in the presence of a wide variety of customer usage and operational environment variations. The application of systems engineering techniques is a key success factor in accomplishing this task - higher quality products at lower cost.
The course goal is to enable the student to apply key systems engineering tools to practical vehicle problems. The basic three-step systems engineering process, comparison of the two different systems viewpoints and key methods and tools in each of these domains will be presented. Student exercises, drawn from practical vehicle problems, will be conducted and evaluated during this class. Integration of the two different systems viewpoints to create a vehicle conceptual design that fully satisfies customer requirements for the entire vehicle life cycle will be illustrated. Finally, translation of vehicle requirements to the manufacturing domain and how systems engineering methods and tools enable reliable and robust design will be described.
Learning Objectives
By attending this seminar, you will be able to:
- Describe the basic systems engineering three-step process and the important inputs and outputs of each step
- Describe the vehicle architecture viewpoint and indicate why it is critical to vehicle commercial success
- Describe the vehicle functional viewpoint and indicate why it is critical to vehicle customer satisfaction
- Create hierarchical functional diagrams
- Employ physical and functional models to create p-diagrams in support of ensuing FMEA as well as reliability and robustness engineering (Design for Six Sigma)
- List the four types of verification that can be employed to ensure complete conformance to customer and commercial requirements and discuss the advantages and disadvantages of each type
Who Should Attend
The systems approach is useful to engineers who already know the basic function and design of their subsystem. Any engineer responsible for ensuring excellent physical or functional interaction with neighboring subsystems should attend. In addition, engineers responsible for understanding customer wants and needs and subsequently translating them into engineering requirements will learn specific methods that enable this difficult translation to succeed. Engineers responsible for creating a vehicle architecture and managing the subsystems that fully respond to vehicle requirements will benefit from this course, and finally engineers responsible for specifying allowable part variations to the manufacturing and supplier communities will understand how these specifications link to critical customer, vehicle and subsystem requirements.
Prerequisites
Participants should have a Bachelor's degree in engineering or science and some professional experience working on a specific vehicle program or subsystem.
