Mechanical Engineering and Vehicle Engineering

Course 1: Mechanical Engineering and Vehicle Engineering: From Automotive Component Design to Vehicle Automation and Electrification

I. Course Description

With the continuous development of science and technology, the automobile industry is undergoing unprecedented changes, gradually shifting from the traditional mechanical engineering field to the innovative development of integrated automation and electrification technology. This trend not only brings new challenges to the mechanical engineering profession, but also provides broader possibilities for the design, manufacture and operation of future vehicles. From traditional component design to modern vehicle automation and electrification, has become one of the important issues facing mechanical engineers.

This course teaches the basic principles of mechanical parts design through the examples of consumer cars. Consumer cars are a kind of common machines widely used by the majority of people. These machines, driven by energy, perform specific actions to apply the required force size and direction, thereby achieving controlled motion. Engineers face challenges in mechanical parts design in ensuring that the car and the product lines they make are safe, efficient and durable. As an introductory course to achieve these objectives, this course provides an overview of concepts including power transmission, gear, bearing, lubrication, clutch, brake, shaft, screw, load analysis, fatigue and material selection.

II. Professor Introduction

Diana Haidar – Tenured professor at Carnegie Mellon University

Diana Haidar Professor is now working at Carnegie Mellon University as a tenured professor of Mechanical Engineering at the School of Engineering, and leading the new maker ecosystem project Maker Ecosystem. In addition, Diana is the chairman / Director of Education of the TechSpark Academic Committee at Carnegie Mellon University and a member of the American Association of Engineering Education. She has made important contributions to the development of technology education and STEM fields through her active participation in various organizations and committees, as well as her persistent pursuit of education and innovation.

Dianas research interests include 3D printing, mechanical engineering, engineering, and a focus on the development of metal and polymer nanocomposites to improve their performance in extreme environments, for which she designed, manufactured and built a variety of customized testing equipment for the testing of these unique materials.
