Description
This is a course Centered around solving a Mechanical design problem of Designing a Vehicle Jack for a certain application for a vehicle. Its a unique course which not only covers the CAD modelling part of mechanical design but combines it with first principle explanations of the working mechanism and Force analysis .It is a "Over the Shoulder " training walk-through of solving a problem step by step and learning by doing. What is covered in the course?Basics of a Car jack - the parts, function The Problem definitionDeveloping a Concept sketch which is parametric to guide the CAD design Detailed CAD design of each part and construction of the assembly of the Jack .Design calculations to find the Forces in the system Understand the basics of Lead screw , thread specifications and the working principle of inclined plane applied to threads. Calculations for Torque in Operating the JackFinding the conditions for self locking of the Jack screwDesign calculations to evaluate strength and stability of the screw and pinsDiscussion on Failure modes and ways  to improve design  to counteract them It is a Fully practical course with all  the course material available for download.The best value you can derive from this course is by designing the device with your own dimensions and inputs. All the Guiding steps are provided to arrive at a basic fully specified design. A Basic Working level knowledge of Autodesk Fusion 360 - the free mechanical design software will be necessary but most CAD modelling is step by step with explanation of each workflow .
