Talk:Shock absorber

message: According to this article, hysteresis is internal friction within springs and the chassis of a vehicle that dampens oscillations, but according to the hysteresis article, it is lag in a system, such as an inductor's reactivity or a piece of iron retaining a magnetic field for some time after leaving the field that originally magnetized it. These seem to be two different uses of hysteresis and I am confused as to whether they are the same or this article is using incorrectly and should be using "internal frictional forces" or something similar. 136.176.8.16 15:59, 21 September 2007 (UTC)

message: The Trophy Truck article mentions coil-over, internal and external bypass shocks.  Can someone explain these three types of shocks?--68.188.157.172 (talk) 16:51, 1 January 2008 (UTC)
thread_title:  Other types of shocks? 

message: The animated GIF image is misleading. It shows large changes of volume of the air (and the hydraulic fluid) in the damper / shock absorber as the piston moves.
IMPORTANT: The volume of hydraulic fluid in monotube shock absorbers is constant. 
The piston usually has ports in it, allowing it to move with resistance through the fluid. The displacement of fluid within the cylinder is slight, being caused by the change in volume of the rod (which is shown over-size) that the piston is attached to within the cylinder, and the gradual expansion of the hydraulic fluid with temperature.
The piston has constricted ports, so that when a force is applied to it, the piston moves through the fluid, encountering resistance. The energy dissipated in the fluid being forced through the piston ports heats it, causing it to expand.
Please amend the diagram 
* reduce the thickness (diameter) of the piston rod
* show that the volume of air within the cylinder only changes a little as the piston moves
* indicate that the fluid passes through ports in the piston.

thread_title:  Animated image is incorrect, cleanup required 

message: I suggest revising the article along these lines: Any comments?
Comparing a worn out shock absorber with a new one shows that the worn one offers little resistance to the motion of the piston, but the good one is much stiffer.
When the wheel encounters a bump, a worn shock absorber's piston provides little resistance to deflection, moving quickly through the fluid. This allows the wheel to bounce up and down (oscillate) relative to the car, and the car to oscillate relative to the road. Excessive movement of the springs and suspension joints increase the stress on other parts of the suspension, causing failures (often on the corner of the vehicle opposite to the faulty shocker). Vehicle handling and braking are also affected.
The resistance to movement provided by a good shock absorber allows the spring to deflect only relatively slowly. The shock absorber both transmits much of the shock load directly to the chassis, and damps the resulting oscillation of the wheel-suspension-vehicle system. The friction of the piston moving through the fluid converts the kinetic energy into heat, heating the hydraulic fluid in the shock absorber. The terms shock absorber and damper are thus both valid, though in engineering the latter is preferred.

thread_title:  Description 

message: It's fine that this article has lots of information about the history, etc. However, most people visiting this page would like info primarily on modern cars' shock absorbers.--75.83.69.196 (talk) 00:34, 7 June 2011 (UTC)
replies: text: I suspect this is because this article suffers from an overdone round of group-think with too many editors contributing random bits of information without considering the overall article flow or intent.  Honestly, I think the entire article should probably be gutted and rewritten from the beginning, with an emphasis on vehicle shock absorbers and a list of the myriad different kinds of shock absorbers in a "See also" section at the end.

thread_title: Generality is good, but most people want info on modern cars' shock absorbers

message: I've removed the annotation, because it was obviously not correct, pneumatic shock absorbers don't have oil in them, and even if some types do, the volume of the oil cannot change in the way shown.
I would have replaced it, but I don't know the correct terms used. Does anyone have a reference for this?Teapeat (talk) 17:54, 21 August 2011 (UTC)

message: I had added a link to Cushioning in the 'See also' section.  This was removed without reason.   It  would seem obvious that the two subjects are related.  Readers of this article might be interested to know of the article on cushioning as used in packaging to isolate shock.  Please explain the deletion.   Rlsheehan (talk) 20:25, 3 December 2014 (UTC)

message: For some reason typing "Shock absorber" into the search bar brings you here, while typing "Shock Absorber" brings you the article on Dashpot, which seems kind of silly to me. I don't know how to change that, or I would do it myself..45Colt 20:26, 26 September 2015 (UTC)
