Linkage Program

I finally got around to finding and fixing a few tiny things. The biggest fix was to the code for sliding links. A sliding link is a link that has two sliders that make it move along a specific linear path. I had code to handle the case…

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…

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…

First, some ass-wipe spam user registered on this blog. They didn’t even comment and just stuck a user account here. I hate these people. I’ve never been robbed at gunpoint but I get phone spam, email spam, and now blog spam, many times a day. I guess that’s…

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…

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…

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…

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….

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…

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…
