Yes you have it exactly. What I am after is the "core logic" that the systems as a whole were built to address. I want to understand components through their role in a general framework so that I can apply reasoning and critical thinking skills to unfamiliar problems within the domain.
With a...
Hey Mr. Beikmann,
I think our methods differ because we have different goals. As an engineer working in powertrains I think the scope of work is more narrow and the quality and specificity is much greater.
But I am a technician so the details are less important than the broad concepts...
Thanks Jack,
The suspension design of some rear wheel drive vehicles I have looked at with trailing arms on both sides has an interesting effect.
It causes the rear axle to rotate as the suspension travels so that the nose angle at the pinion shaft changes symmetrically with the joint at the...
Awesome reply Mr. Beikmann.
How will the oscillation or vibration affect drivetrain clutch engagement?
Won't it lead to a rough stick-slip condition until the load is fully coupled?
Clutches don't have their full clamping force from the start, the engagement would be very harsh if they did...
Putting a car in gear and holding the brakes and full throttle is a common way of checking the mounts, drive or reverse. Excessive movement indicates a weak mount that needs replacement.
Likewise with automatics the test has been used to check maximum engine power output and compare to see if...
Hello,
As I understand it there is an equal and opposite reaction for every mechanical action. In the case of a vehicle drivetrain the engine generates a torque at the flywheel or flex plate which becomes an input to the transmission and ultimately the wheels.
The rollong resistance of the...
Hello,
I greatly appreciate everyone's responses and instructions. Unfortunately work and home life has prevented me from studying for awhile so I have not been able to follow up on the research.
I will look into the book OldEngr63 recommended. I intend to work with automotive machinery for...
I was referring to this concept:
http://www.easyflex.in/pdff/latest/Vibration%20Isolation%20Theory.pdf
Vibration is a force and establishing an opposed force can effectively reduce its transmission. This is
accomplished by incorporating a truly resilient material, which when subjected to a...
Is natural frequency an intrinsic property of all systems and objects or just more pronounced in some? To have a natural frequency wouldn't you need a system or object capable of storing and transmitting energy?
In the case of rubber some of the energy is lost to the deformation, and that...
Hello,
I am studying and trying to understand Powertrain / Engine mounts used in automotive such as these:

Here is an interesting forum reply apparently from a General Motors RF Engineer.

I'm an automotive technician working at a dealership and I am working on a car with intermittent issues with wireless communication with the tire pressure sensors which are mounted inside each wheel.
I went searching for the location of the particular antenna that serves the tire pressure...
Thank you Jack,
This is a bit beyond my education, particularly using math to describe the relationships.
But I am trying to wrap my head around it nonetheless.
It seems to me that Hardening a steel shaft means that it will break with less applied torsional/shear stress than one that isn't...
The only thing I have really learned is that for a given amount of mass it seems it is better to make a shaft hollow than solid. This is because for a straight/solid shaft, the center does not move very much for each degree of angular deflection.
When all the mass is concentrated at the outer...
Hi,
I'm a mechanic and I need to settle a point with a fellow mechanic.
I was describing how a 3/8"s extension twisted during use, and I said maybe I need one that has been hardened properly. As in *through hardened*.
He said I am confusing hardness with rigidity. And to look into...
