Linkage 3.0?

I was working the last few nights on an update to the linkage design and simulation program. I have started the process of adding linear actuator support. Until now, rotating inputs were the only type of input available. I have a working mechanism although I have no way…

Ribbon Bar Working in Linkage 2.0

I now have the linkage program working with the new ribbon bar. I’m not sure if it’s much better than the old-style toolbar but it’s prettier. I wanted to use an image gallery in the ribbon bar to select sample mechanisms but even with 128×128 pixel images, it’s…

Solid Links and Thick Lines

I am still stumped on how to simulate the link/slider/slider mechanism I described in an earlier post. I think that there is just no way to do this with math since the curve I need to intersect can only be described with an equation that includes a time…

Another Special Case!

And another and another. I found another case that requires special code to deal with the geometry that is different from all other cases. the thing to notice in this situation is the fact that connector C controls the location of link 1 horizontally in this case but…

More Special Cases

I was back at work last night writing code to handle special cases in the linkage simulator. It turns out that every type of connection is a special case, almost. Here is what I have working: There is one case I can see that is missing but the…

How the Simulator Works

I thought I might write down some points about how the simulator works for future reference and to help me think about it and make improvements. The linkage program is a bit experimental so I try to get something working and then worry about making it better later….

Special Cases for Sliders

This is another special case. It seems like the sliding connectors have many special cases. I thought that there were three but now, with this one, there are four. The good news is that I have the two more normal cases working. They are the cases where there…

Sliding Connectors in a Mechanism

I did some work on the linkage simulator last night. I think I’ve narrowed down the sliding connector issue in the linkage program. There are essentially three situations I need to handle. Consider these images: Figure 1. In figure 1, A and E are fixed. F will be…

Linkage Simulator

10/7/2014 See the most up-to-date information about the Linkage program here: linkage-mechanism-designer-and-simulator I have a spare minute while I’m running a debugger and waiting for the my program to get to the bad data it is supposedly processing. The program usually runs a few minutes with optimizations, etc…,…
