Thank you all very much! I have finally made a decision! I talked to yet another engineer at Algor and discovered that it does have the full capabilities that I need. They explained to me that I can create my own load curve that is dependent on the velocity in a nonlinear manner for dashpod...

Wow! Thank you all very much for your input! I think I am really starting to narrow things down. I hope you are all having a wonderfull thanksgiving (depending if you are American or not)! I already had mine:) Gbor I appologize for my asumption. After I read your comments a second time I...

Gbor I have looked into Algor. I must say they do have a really good customer support set up. The only thing that I am hesitant on is that their dashpot damping system only seems to support viscous damping. I'm not sure that it has the flexibility that I need. Perhaps I can do worse case...

GregLocock Sorry about that. I realized after I read your response again this morning that it was obvious that you were referring to the front forks. Strain gages seem to be a good approach since I shouldn't have to alter the prototype to install them. Thanks a bunch for your willingness to...

Greg Thanks for the tips. I'm sure there probably are some rules of thumb. It's a pretty competitive world out there! Perhaps I'm looking in the wrong places though. I would gladdly accept any helpful rules of thumb that could be offered. I would greatly appreciate an example of that excel...

BGor, I will check out Algor as well, thanks. GregLocock, Thankyou very much for the breakdown! I am find that step 1 is very difficult. I have been trying to solve the forces of my system using vibration theory combined with dynamic analysis including kinematic calculations but I keep...

Thanks a bunch for all your responses! Right now I am concerned with over the road motion. I also have a number of other frames that I will have to model. I need an efficient system. Currently I don't have any software. I would like to use Cosmos because I don't want to have to remodel...

He I am trying to decide What FEA package I should buy. I need to model the rear supsension of a motorcycle. I hope to be able to animate it and determine the stresses the rear swing arm, axel and differential will be subject to. I would like to model it in Solidworks but am wondering if...

thundair Thanks for the heads up. I have sent an email to John List. Hopefully he can help. Blessings

Thanks alot guys! Yeah, I think I would like to design an aluminum differential, but I will have to see how soon my boss wants the first prototype ready. I have a few other major tasks to complete first before I can start redesigning a differential. You guys have been a great help! I hope...

Thanks a lot guys! You have all been really helpfull. The A356 T6 sandcast sounds attractive but it's elogation before break is only 3% and it's strength is 20ksi. The differential will take a fair amount of pounding since it is part of the unsprung mass in the suspension rather than the sprung...

carnage1 My only problem with extrusion is the price of material will be more and the process of machining will be quite extensive. A cast part comes already hollowed out and close to the dimensions of the finished product leaving only a little left to machine. The die will cost a fair bit...

NickE I should have specified aluminum casting in my reply to carnage1. I think it is the "aluminum" casting that he is cautioning me against. Blessings

carnage1 Thanks for the warning. What are your concerns with using a cast housing? Blessings

Yeah I like your suggestion, except I'm not even sure of what type of questions to ask. I wish I had some more experience in this area so that I knew what to ask and watch out for. Blessings

rtmpxr Thanks for the guidance. What are your comments on the technical support? Is ANSYS good for answering questions. Are they more than willing to help? Blessings

Frederick Thanks for giving me details. Do you have any suggestions for the carrier material. I know ductile iron could be used but I also heard that aluminum alloys work well too. I was thinking of a AA 356 sandcast or a 6061 T6? Blessings Drew

Thanks alot for your responses! I'm not too worried about the cost. I'm actually designing rear-ends for motorcycles. We are converting bikes to trikes and I need a good idea of the correct material to use for a pumkin (differenctial housing). Blessings

I am trying to get an idea of what material to use if I want to build a differential for a very small vehicle? Does anyone have recommendations? What do most automobiles have? Blessings :)

kiwinjuneer and carnage1 Thank you bothe for your suggestions. kiwinjuneer I have been looking at the sae papers available and have purchased a few. I think I will have to look for more though. I have started a thread in this forum and have already started getting replies concerning the...
