I have created a toggle link force calculator in Inventor. I got the equations from https://www.engineeringtoolbox.com/toggle-joint-d_... and used the arms of UNEQUAL lengths set up. Now, the issue we are are trying to figure out is what is the actual force we can apply without stalling the cylinder. I have attached a picture of the model. Because of how the equations for toggle links work, as your angle approaches zero between the links(top dead center - TDC - as we are calling it), the force goes to infinity...which we also know is not the case. So, is there a way to determine that if I have cylinder appliing say, 600 lbf on the bottom of the link, what is the true amount of force it can push against, before it can't go past TDC?
Functional prototypes are a key step in product development â€“ they give engineers a chance to test new ideas and designs while also revealing how the product will stand up to real-world use. And when it comes to functional prototypes, 3D printing is rewriting the rules of whatâ€™s possible. Download Now
