MIT OpenCourseWare: New Courses in Mechanical Engineering

2.081J Plates and Shells (MIT)

Wierzbicki, Tomasz — 2008-09-04T12:27:00-04:00

This course explores the following topics: derivation of elastic and plastic stress-strain relations for plate and shell elements; the bending and buckling of rectangular plates; nonlinear geometric effects; post-buckling and ultimate strength of cold formed sections and typical stiffened panels used in naval architecture; the general theory of elastic shells and axisymmetric shells; buckling, crushing and bending strength of cylindrical shells with application to offshore structures; and the application to crashworthiness of vehicles and explosive and impact loading of structures. The class is taught during first half of term.

2.004 Systems, Modeling, and Control II (MIT)

Barbastathis, George — 2008-08-08T05:58:24-04:00

Upon successful completion of this course, students will be able to: • Create lumped parameter models (expressed as ODE’s) of simple dynamic systems in the electrical and mechanical energy domains • Make quantitative estimates of model parameters from experimental measurements • Obtain the time-domain response of linear systems to initial conditions and/or common forcing functions (specifically; impulse, step and ramp input) by both analytical and computational methods • Obtain the frequency-domain response of linear systems to sinusoidal inputs • Compensate the transient response of dynamic systems using feedback techniques • Design, implement and test an active control system to achieve a desired performance measure Mastery of these topics will be assessed via homeworks, quizzes/exams, and lab assignments.

2.996 Biomedical Devices Design Laboratory (MIT)

Ma, Hongshen — 2008-07-30T10:16:02-04:00

This course provides intensive coverage of the theory and practice of electromechanical instrument design with application to biomedical devices. Students will work with MGH doctors to develop new medical products from concept to prototype development and testing. Lectures will present techniques for designing electronic circuits as part of complete sensor systems. Topics covered include: basic electronics circuits, principles of accuracy, op amp circuits, analog signal conditioning, power supplies, microprocessors, wireless communications, sensors, and sensor interface circuits. Labs will cover practical printed circuit board (PCB) design including component selection, PCB layout, assembly, and planning and budgeting for large projects. Problem sets and labs in the first six weeks are in support of the project. Major team-based design, build, and test project in the last six weeks. Student teams will be composed of both electrical engineering and mechanical engineering students.

2.372J Design and Fabrication of Microelectromechanical Devices (MIT)

Livermore, Carol — 2008-07-28T04:00:26-04:00

Introduction to microelectromechanical devices (MEMS). Material properties, microfabrication technologies, structural behavior, piezoresistive and capacitive sensing, electrostatic actuation, fluid damping, noise, amplifiers, and feedback systems. Student teams design microsystems (sensors, electronics, and feedback) to meet a set of specifications (sensitivity, frequency response, linearity) using a realistic microfabrication process. Emphasis on modeling and simulation in the design process.

2.003J Dynamics and Control I (MIT)

Sarma, Sanjay — 2008-06-09T12:36:30-04:00

This class is an introduction to the dynamics and vibrations of lumped-parameter models of mechanical systems. Topics include kinematics; force-momentum formulation for systems of particles and rigid bodies in planar motion; work-energy concepts; virtual displacements and virtual work; Lagrange's equations for systems of particles and rigid bodies in planar motion; linearization of equations of motion; linear stability analysis of mechanical systems; free and forced vibration of linear multi-degree of freedom models of mechanical systems; and matrix eigenvalue problems. The class includes an introduction to numerical methods and using MATLAB® to solve dynamics and vibrations problems.

2.00B Toy Product Design (MIT)

Kudrowitz, Barry — 2008-06-19T11:08:47-04:00

Toy Product Design is a MIT Public Service Center learning design course offered in the Spring semester. This course is an introduction to the product design process with a focus on designing for play and entertainment. At the end of the course, students present their toy products at the Playsentations to toy designers, engineers, elementary school children and the MIT community. In this course, students work in small teams of 5-6 members to design and prototype new toys. Students work closely with a local sponsor and experienced mentors on a themed toy design project. Students will be introduced to the product development process, including: determining customer needs; brainstorming; estimation; sketching; sketch modeling; concept development; design aesthetics; detailed design; prototyping; and written, visual, and oral communication.
