Thank you very much for your answer rb1957!
Here is my personal ranking of the 4 (I initially grouped Structures and materials as one):
1. Structures
2. Materials
3. Aerodynamics
4. Propulsion
Coincidentally it matches what the demand trend you laid out. I feel that even though I want to go...
I was just thinking about that. A lot of people graduate from college with the intention of coming back but due few actually do. My initial plan (still what I am considering) is to finish with academia at once by completing my masters while getting industry experience through internships. I do...
Wow didn't think of that. That's actually a good point. So ideally if I get a job right off college in the aerospace field that offers rotational programs giving me exposure to the above 3 fields I should be better able to decide what to pursue a masters in. Thanks for that! Most of my...
Hi,
I am about to start my last year in undergraduate as a mechanical engineering student with a focus on product design. I wish to go on and complete my masters at once in the aeronautical field. From all the different fields I could specialize in (controls, avionics etc) I have narrowed my...
Thanks for your reply. Forgive me for not having mentioned this: I wish to know about machinable (not cast) aluminum alloys that can be used for steering knuckles.
Hey Bob, question for you. Are you familiar with Aluminum 2024? As I was searching for what material might be suitable for the knuckle, I came across this website http://www.emachineshop.com/machine-shop/Custom-Aluminum-Parts-Machining/page486.html from which it seems as though aluminum 2024...
Hi,
I would like to know what aluminum alloys are used in making steering knuckles? So far most of the studies I have found use Aluminum 2011 T3.
I would also like to know properties in general should the aluminum alloys have for such an application? From another thread I started, I know...
Thank you Bob for the ASTM reference. I was able to find a prior version too.
I have a question about the FEM analysis; I reran the individual loading cases changing where I apply the loadings and where I constrain the DOFs. Again, the max stress I got was less than the ultimate tensile and...
Got it. So I will be right in concluding a different material will be more suitable then?
Hey Bob, will it be possible for you to look up the actual elongation at failure of aluminum 7075? If it is not asking too much, can you also look up the ultimate, yield and shear strengths and the modulus...
"Yes, 11% is too low for use on suspension parts. 15 is ok, 18 is better. For track use you'll get away with it if you aren't running the kerbs." Would it be possible for you to explain this a little to me? Also would you recommend using a different material in this case?
Bob I will be sure to...
It is about 11% at failure. I got all my properties values from here http://asm.matweb.com/search/SpecificMaterial.asp?bassnum=MA7075T6. Something that concerns me about those values however is that next to them they have "AA" annotation and according to that page anything value with "AA" should...
Thank you very much Greg for your input and for the other threads you directed me to. It cleared up a lot for me.
I subjected my knuckle (aluminum 7075 not steel) to the individual 5-4-2 loading scenario and then combined the maximum stresses (square root of the squares). In each loading case...
That makes a lot of sense. Thanks.
"I am not going to speculate what "X" needs to be, in any of the above" How would you say I should go about determining what X should be then? Like for braking and cornering I am using 1.5G as in the articles but for cases like bumps I am not exactly sure how...
Thank you for your replies. So the G-force in this case will be whatever is supported by the wheel at static condition then.
@Greg I was thinking of applying all the forces at once (mainly braking, cornering and gravity) and if the part withstands that, then start cutting out material where...
Hello,
I am trying to carry out FEM analysis on a steering knuckle. I have found some articles with typical braking and cornering loads to apply and they are all expressed in G-Force (here are two the articles I found...
Thank you both for your answers. That clears up a lot. Just so as to make sure I am getting this: as long as all the other parts are well defined and set, the caliper can pretty much go anywhere. There are some positions such as "below and behind the centerline" that would be ideal but it can...
Hi,
I have looked quite a bit for an answer to this but with little success. I am in the process of designing a custom steering knuckle and would like to know whether there is an optimimum angle from horizontal or vertical at which brake calipers should be mounted. Most of the moutings I have...
