Introduction

I really love mechanisms and how mechanical systems work, so I decided to design a Crank-Slider Mechanism which transforms the rotating motion into reciprocating/linear motion. The assembly of a piston, cylinder, connecting-rod and crankshaft is the classic form of the slider-crank mechanism where a slider crank transmits motion generated by the linear displacement of the piston by a working fluid to rotational motion of a shaft.

The mechanism consists of 4 elements, a base which is fixed to the ground, link 1 which rotates from 0 to 360 degrees, link 2 which connects link 1 with the slider, a slider which moves along the base generating the linear movement. I will be using GIMP to make a draft for the mechanism, Inkscape for sketching the parts in 2D, XDesign for the 3d modelling and Fusion 360 for assembly, rendering, animating and simulating the mechanism.

Steps in General:


Steps in Details:

Step(1): Sketching the mechanism on GIMP


Step(2): Designing links, base and slider on XDesign


Step(3): Assembling, rendering, animating and simulating the mechanism on Fusion 360

Step(4): Sketching the final project using CorelDraw


Finally, I have:

√ Modelled (raster, vector, 2D, 3D, render, animate, simulate, ...) a mechanism

√ Compressed images and videos

√ Posted in my class page

Issues & Solutions:

  • Issue#1: When I tried to apply a material appearance for each component, there was no change!
  • Solution#1: I found that it is a must to break the link between the component in the assembly environment and its original source.
  • Snow
    Forest
  • Issue#2: When I uploaded the parts in .step format to be downloaded, there was an error and they could not be downloaded through the browser!
  • Solution#2: I compressed the files in .rar format instead of .step and it worked well.
