There is a package that I am now using called MechDesigner. It allows you to simulate complete machines, with many axes or mechanisms, generally packaging or assembly machines, using full kinematic solutions rather than just 'solver' based solutions, with motion designs assigned to the relevant...
Nice to see SI units for a change.
And yes, rb1957, I do get annoyed when term 'acceleration rate' is used instead of straight 'acceleration'. Acceleration rate would mean 'jerk', or the third derivative of position or angle etc.
TwoBallCane - it is very common for objects to have acceleration...
Just a point - if the outer race creeps then it can be summized that the housing is not supporting the outer ring. This means the outer ring will distort, or not be quite round. This is NOT good. Outer rings can afford to be 'thin' because it is usually expected that the housing supports the...
Ok, here is how the mechanism posted by the OP works (with artistic license) - a very simple 4-bar mechanism. Now the only question remaining is ... what does the OP need to do again? To me, the design is all but done in the 3D static CAD...
BugE. You are right - I thought Forces were included as it promised on the old website. I for one am going to keep my eye on it as I know Camlinks was pretty useful and if this is going to be 3D version, then i'll be very interested.
In answer to zekeman, if I put it in to a 'cambox' where the OP could only see the input and output shaft, then he would never really know he had a 6 bar! I could be really sneaky and just tell him/her to never, ever, on the pain of death, open the box!!!!
OK here is a 6 bar linkage with an oscillating input of 180degrees with an output link rotating more than 180 and the transmission angles don't get that bad....that's in my humble opinion. Have I missed the requirements though, as I'm not entirely sure what is being asked for....LEt me now if...
Out on a limb here.
I use Help and Manual... It is a help authoring tool. Deals with graphic easily and can publish to paper, ebooks, as well as the web, and normal help files. VERY similar to instruction operation and maintenance manual requirements...
First of all, what are your criteria for success: Before a recommendation, one would need to know both static precision and the dynamic precision you would need. Statically, how much error in position could your design tolerate before it becomes inefective. Are there particular positions that...
I would assume you know how to design a 6-bar mechanism with a traslating link? Because there is a method to do that. You first of all need to find a 4-bar with a coupler curve - or with part of a coupler curve that delivers your horizontal followed by vertical motion - I'd look for a 4-bar...
Just for information: a body released from zero height (ie its weight is totally supported but is touching the surface just so) on to an elastic system (say a cantilevered beam) will deliver no "impact" (ie no diference in velocities) but will initially deflect the beam at twice the amplitude to...
There used to be a package called Camlinks I used in the past. Very good for kinematics and forces (forces due to inertia and springs etc). Friction input was limited, but you could input a constant force if you wanted. I've just done a search on Camlinks and there is a product called...
