MACHINE DESIGN LAB

Lab Incharge : Mr. Anil Gupta, Dr. Sumit Joshi

Lab Technician: Mr. Piyush Motwani

The Machine Design Lab is a comprehensive laboratory course spread across the 4th and 6th semesters of the Mechanical Engineering curriculum, comprising two integrated modules: Machine Design-I and Machine Design-II. The lab aims to equip students with essential skills in the systematic design, analysis, synthesis, and validation of mechanical components and assemblies under real-world loading conditions.

Through a blend of analytical techniques, empirical design practices, CAD modeling (Onshape), simulation tools, and reference design data, students gain proficiency in designing machine elements with due consideration to material selection, factor of safety, performance under static and dynamic loads, and manufacturability.

The lab promotes a practical understanding of the design principles involved in power transmission, load-bearing elements, automotive systems, and heavy machinery components—bridging the gap between academic knowledge and industrial applications.

Key Equipment & Models in the Lab:

The Machine Design Lab is equipped with industry-standard models and components that allow students to study, analyse, and apply machine design principles effectively:

  1. Design & Transmission System Models
  • Helical Gears
  • Spur Gear
  • Clutch Plate
  • Shaft and Coupling Systems (Rigid, Flexible)
  1. Joints & Power Transmission Elements
  • Spigot and Socket Cotter Joint
  • Knuckle Joint
  • Pipe Joint
  • Riveted Joint
  • Welded Joint
  1. Lifting & Load-Bearing Elements
  • Screw Jack
  • Crane Hook
  • Wire Ropes
  1. Automotive & Engine Components
  • Connecting Rod
  • Piston-Connecting Rod Assembly
  • Double Shoe Braking System
  • Gearbox Models
  1. Bearing & Support Systems
  • Ball Bearings
  • SKF Catalogues and Design Manuals

Learning Objectives:

By the end of this course, students will be able to:

  1. Understand the systematic procedure for designing joints, shafts, couplings, and other machine components used in power transmission.

  2. Apply analytical and empirical methods to determine the dimensions and material selection for gears, levers, and threaded systems under static and dynamic loading.

  3. Analyze the stress distribution, failure modes, and safety aspects of load-bearing elements such as crane hooks and wire ropes.

  4. Synthesize mechanical systems such as gearboxes, braking systems, and clutches with a focus on performance, reliability, and optimization.

  5. Demonstrate proficiency in 3D modeling and simulation using Onshape or equivalent software for visualizing and validating mechanical designs.

  6. Evaluate the design of internal combustion engine components, including connecting rods and piston assemblies, considering fatigue and operational loading.

These objectives help students bridge theoretical knowledge with practical applications, preparing them for engineering challenges in automotive, aerospace, heavy machinery, and industrial sectors.
