The practice of mechanical engineering requires the ability to investigate and analyze complex thermal and mechanical systems. An effective way for the students to develop their understanding of mechanical engineering systems is for them to get hands-on experience by working in small groups in a laboratory environment. To provide these opportunities, a required mechanical engineering capstone laboratory course is being revised in this project. The new Engineering Systems Laboratory course is based upon an integrated sequence of laboratory experiments on an automobile and its subsystems. The automobile is chosen as the system to study because it is compact, relatively inexpensive and in the direct realm of experience of most students. More importantly, its many complex subsystems provide opportunities for the students to apply the spectrum of their mechanical engineering knowledge, including the principles of mechanics, dynamics, thermodynamics, heat transfer, and controls. This project is developing a laboratory manual, a series of library/internet research exercises, and an instructor's guide for the course, evaluating the effectiveness of the developed course materials and appropriateness of the course contents, and identifying the appropriate commercial dissemination mechanisms for the materials developed. The materials are grouped into learning modules, and four modules will be produced in this proof-of-concept project.The approach taken in this revised laboratory course is to have the students investigate the same system through a sequence of complex experiments and analyses. The course culminates with the students performing an integrated analysis of the semester's results and recommending changes in the experimental design, the vehicle design, or both. The Engineering Systems Laboratory helps students to develop a systems perspective and also gives the students experience in designing experiments, applying computer-based instrumentation to study system performance, documenting their results in writing, and making oral presentations.

机械工程的实践需要调查和分析复杂的热和机械系统的能力。 学生发展他们对机械工程系统的理解的一个有效方法是通过在实验室环境中的小组工作来获得实践经验。 为了提供这些机会，一个必要的机械工程顶点实验室课程正在修订本项目。 新的工程系统实验室课程是基于对汽车及其子系统的实验室实验的综合序列。 选择汽车作为研究的系统，是因为它结构紧凑，相对便宜，并且是大多数学生的直接经验领域。 更重要的是，它的许多复杂的子系统为学生提供了应用机械工程知识的机会，包括力学，动力学，热力学，传热和控制的原理。 该项目正在编写一本实验室手册、一系列图书馆/互联网研究练习和课程教员指南，评价所编写的课程材料的有效性和课程内容的适当性，并为所编写的材料确定适当的商业传播机制。 这些材料被分为学习模块，在这个概念验证项目中将产生四个模块。在这个修改后的实验课程中采取的方法是让学生通过一系列复杂的实验和分析来研究同一系统。 本课程的高潮是学生对学期的结果进行综合分析，并建议改变实验设计，车辆设计或两者兼而有之。 工程系统实验室帮助学生发展系统的观点，并为学生提供设计实验，应用基于计算机的仪器来研究系统性能，以书面形式记录结果以及进行口头演示的经验。
