EdStainless,
In the image it shows the strip was machined from it (lengthwise strip) 0.2500" wide and 0.1200" thick. My thoughts exactly. I want to ask for a graph (not provided).
Hi all,
I recently had an aluminum sample tested for composition and tensile strength. The composition looked close to 7050, but just slightly off. The tensile was much higher than I expected or am aware of how to achieve. This was a tube more or less (image attached).
How do you...
My question is regarding reliably transmitting torsion via a shaft in a safety critical application. It seems like composites are often kept out of such scenarios where there is no redundancy and safety is critical of the component. I want to know of some scenarios where they are used like...
Im not familiar with the Gillespie book to honest. Its neat that you tried to get a hold of him though. Thank you for presenting your method!
The reason Im not using just sprung output over road input is that it leaves out whats actually going on at the contact patch which for the moment is...
For the front wheels...
With static toe in as you initially steer or are tracking strait with minor adjustments you increase slip angle on the outside tire and decrease it on the inside. This has the effect of increasing the pneumatic trail and slip angle drag on the outside tire and reducing...
Given a simple 4th order quarter car model where you have the sprung and un-sprung mass and no tire damping I'm trying to develop a useful and robust way of specifying damping rates.
My present path is to use a bode plot of tire spring deflection (power output from tire spring might be useful...
Hello all,
Im putting together a simulation and will need some values of the moments of inertia about each axis. My thoughts were that a BMW 3 series, Ford mustang and a wrx may have a similar radius of gyration about the longitudinal axis (call this the x-axis). A corvette, 911, F430...
Most equations for chassis design involve the tires cornering stiffness which is zero at its peak lateral force for a given condition. Just looking in Miliken this zeros out a lot of values if you were designing a neutral car that in theory all tires reached the limit at the same time or if you...
Here is the picture Greg. BTW LBJ is 0 on the length scale.
The two bushings are being simplified as point loads at their centers. I don't think its statically indeterminate, I could see that if the bushings were connected to the same ground as the LBJ and top bearing, but they are internal to...
Ive got a free body diagram set up, but Ive confused myself into balancing it out a few different ways if you can believe it. Im trying to determine the lateral loads on the internal bushings under a load by applying a torque at the lower ball joint. Basically I am trying to get a ballpark...
This is fairly common among auto crossers and some road racers to improve on center steering response for turn in at the expense of braking stability usually. I dont understand how toe OUT up front improves on center response, it seems counter intuative. Unless drag forces from inside tire are...
Ive got a debate going over an idea i had about the possibility of torsional resonance or oscillations with in a tosion spring. The current use of the torsion spring is about 20" long and .5" diameter with a .035" wall thickness. At each end is an leverage arm that recieves an input of often...
Your comments about road feel are interesting. Please correct any misunderstanding if you see any. In the past I have looked at steering geometry of some cars with great road feel like the nsx and the old elan's, and no obvious scrub offset or trail or castor/kingpin inc. etc was ever tied to...
