If you liked this, I highly recommend reading "Kinematics and Dynamics of Machinery" by Norton, it shows graphical examples and solutions to 4 bar mechanisms with specified motions.
What?! I’ve always been curious about the complexities of engineering similar mechanisms... I had no idea it could be this simple. Very succinct explanation and example. This video coupled with the 3D printer I got for Christmas, whew, I’ve got some stuff to make! Thanks!
What is lacking with Mechanical Engineers today, is the knowledge of how to design mechanisms correctly. Did know that there's a mathematical formula that can be used for all mechanism designs? It's called Gruebler's Count. I found a way to make it practical for all 3D mechanisms. Here's the link if you are interested. ua-cam.com/video/KFB8gMjxDPk/v-deo.html
This video is amazing! I have always wondered how people design different hinges for cabinets and stuff. Now I can create my own for a 3D-printing project I am working on! Thanks a lot! 👍
Awesome. Game developer here, currently learning CNC/VMC programming and solidworks. Doing 3D modelling is one thing, but the science & Engg behind the mechanism is another thing. What things do I need to study, to create mechanism of my own. ANother reason to learn this is, in modern games, such as Red Dead Redemption 2, we see horse animation, its all procedural, meaning the motion is all mathematical, there is research paper on how it is done. By learning this, it will also help me create procedural animations, also Animatronics also uses these things I guess. This is so insightful. Thank you for sharing. Have a great day ahead.
Very nice video. You can also do a simpler approach: make a circle using the 3-point circle method through all three points A. Do the same with points B. The center of the circles is the chassis pivot.
I don't even... how do... wha.. When you see it come together... I'm 40 and today I leveled up thanks to your video. 20+ years of drawing and milling experience never had a clue as in to how to begin to tackle this things... and the timing! I HAVE to do one of this things for a project I'm working on... I mean, dude, Thanks A LOT!
Thanks for the video. It helped me tremendously. I just wanted to add my alternative to your method. Instead of drawing lines between the points, then bisecting them with perpendicular lines, you can just draw at 3-point circle using A1, A2, A3 as the points. The center of the circle is the exact same place your intersecting lines meet. Do the same for the B points and bam, done.
@@vitof.4626 That's really fun to play with! I like that by just defining a start and end with the two circles connecting them, you can play more freely with the motion and easily try many cool motion paths. Thanks for the suggestion!
Hi, I just came across your excellent video whilst researching linkages and it has really helped me understand. Can you tell me what version of SolidWorks you have as there are so many to choose from. I would like to be able to do the linkage models as you show here and I just want one of the free download versions if possible. Thanks for sharing.
Awesome video. I wished I had solid works. Question, working on a project although hinge needs to be on the outside. Was wanting to design a hinge to be pulled by a lever or actuator to open the grill lid. Any ideas designing from the outside?
Thanks! As far as your hinge setup goes, the pulling actuator should work as long as the force and travel needs are met and the actuator doesn't run into anything. Also, you could look into a pushing setup if you move pivot joints outside of the pit sides (if I'm picturing it right).
Thank you so much! This is a great video, one of thee most important I've ever seen. I'm an electrical engineer by trade, but I like to dabble with mechanical stuff. I like to build stuff in Solidworks and make 3D prints from them.
I've been trying to get my head around a crank -rocker mechanism with the desired range of motion. I thought I understood it when I got my first solution but apparently, not.
Recently realized mechanism design might be one of the most important subjects in mechanical engineering. Thanks alot for the presentation. Wish to know if there are some books you might recommend for this
great video! Really helped. I was wondering if this technique also works if I have a 4th or a 5h position. Will it then become a 5 bar or 6 bar linkage?
There are techniques to add more positions but the process grows in complexity. As far as growing to a 5 or 6 bar linkage that depends on the situation. Adding links can accomplish more complex geometry but most applications add links for specific purposes. I've made a 4 into a 6 not because I needed a more complex path but because I needed to add a force into the mechanism and bars 5 and 6 allowed me to tune the force input for ergonomics along the travel of the mechanism.
Wow! Amazing! Thanks for sharing. I have a question, is it possible to construct more elaborate spatial mechanisms using 3D sketches with this technique?
First of all thanks for the video Man! Thanks for the great explanation and simplication of construct the required mechanism. I loved the procedure the way you have explained. Thanks a lot for giving a clear view to crack those type of mechanisms. Could you please tell me on which platform that I can do those things? Plz this will really help me to crack a my own mechanism.
@@DirtyElbowsGarage Thanks for the response and suggestions! Explain few more mechanisms especially *(NUBIKE leverage mechanism)* that will help me a lot. Thank you.
Thank you that was awesome! Do you have a reference book or know of a set of lectures that explain the methods of forming all of the well know mechanisms?
Hey, thanks for ur video. In the video without dimensions you defined a 4 bar mechanism that mimics the movement you want. But in order to get real model how you defined dimensions and preserve the exact movement ?
Hello: Could you demonstrate when you have a limited space, as in the trunk example, when you have convergence points way out there as your example shows. Thank you.
I figured out another solution. If your CAD software has 3 point arc or circle tool (I'm not familiar with Solid Works), you can find the location of each joint in bar 1 by drawing an arc (or circle) containing A1, A2, and A3 (and B1, B2, and B3). Perpendicular bisectors is probably what that tool uses "under the hood" to find the center of the circle. One nice thing about this method is that it does not clutter up your sketch as much (2 arcs instead of 6 lines). Another advantage is that it is self-explanatory why it works: bars 2 and 4 trace out the two guide arcs. Now, I can feel smart XD
I feel like the ape who just touched the monolith (...but now I have to learn Solidworks?) Seriously, I've occasionally tried to visualize how these mechanisms are designed for decades. Now, in 7:28, you've done it!
Hey bro, i really didn't think it was that easy, one thing I think might be super useful is to use Sketch Image and take three pictures of you car with the tripod and make the accurate mechanism used in the car and the trunk
This may be the most empowering video on UA-cam. It's literally life changing for me.
If you liked this, I highly recommend reading "Kinematics and Dynamics of Machinery" by Norton, it shows graphical examples and solutions to 4 bar mechanisms with specified motions.
This is the most informative video i've seen on four bar linkages, it's completely demystified it for me.
This deserves a lot more views
Definitely

This is truly amazing, I've been using these tools for years and never even thought to trace a path like that. Incredible !

or draw just two positions of the hood and then a circle A1 to A2 and locate the center of the circle as you want. I learned a lot today!
Wow, you're right. I tried both ways and found your circle method to be much faster. Thanks for sharing!

Thank you!! I’m using this concept to create a lift out floor hatch in my boat. Exactly what I needed to see to get past my mind block 👍😎
I have been looking at how to do this for like over an hour, This is sick! Thank you
Blows my mind. I always wonder how engineers did that on the vehicles. That’s super cool!
Great instruction, thaks. Do you play the music while making the video or is it added later to distract us?
This video was the best. Helped me a lot, Thank you.
Fantastic! I've been looking to understand exactly this concept! Thank you!
