Extended tread life: A micro-silica compound and rounded ribs profile optimize contact pressure
with the road to reduce uneven wear.
When the contact pressure
between chisel and material increases and AutoControl switches from a short piston stroke to a long piston stroke, IPS switches automatically to the AutoStop mode.
An effect of the use of protectors is increased contact pressure
between the rail surface and the seal.
When we find the yield height, we can get the corresponding maximum contact pressure
[P.sub.0], and then the initial yield force and yield displacement can be expressed as (12) and (13), respectively:
Sliding speed (V) and contact pressure
(P) were in the range of 0.015, 0.020, 0.025 m/s (7.5,10,12.5 Hz frequency) and 475, 555, 616 MPa (5, 8, 11 N load), respectively.
To determine the stress distribution and contact pressure
in the elements of friction pair, a wear-contact problem on pressing the plunger into the hub's surface must be considered.
The distribution of contact pressure
between the relatively rigid spherical part of the titanium joint and the much more flexible spherical cup made from polyetheretherketone (PEEK) was calculated by FEM (Finite Element Method, program Abaqus) analysis.
Equations for determining tube-fin interference and resulting contact pressure
are presented herein.
For the baseline piston, it is found that the highest contact pressure
does not occur right at the 180[degrees], or the thrust axis.
The average error between the two trials was determined for peak contact pressure
and contact area.
For instance, the contact pressure
[p.sub.0] between 2 cylinders of length L and radius [R.sub.1] and [R.sub.2], with parallel axes can be calculated as:
