TORSIONAL ANALYSIS Using Pro/MECHANICA Pro/ENGINEER Wildfire 2.0
Dr. Herli Surjanhata
The U-Joint shown in the figure below is made of steel. A torsion load of 10,000 INLB is uniformly applied over the top portion surface of the U-Joint. Determine the von Mises stresses, and maximum deflection under the given torsion load and boundary conditions. Check the convergence of your analysis. Step 1: Using Pro/ENGINEER, create a base feature as shown in the Figure below. It is done by extruding both sides the section shown with 2 inches blind depth.

One of the most important inventions for the development of radars was made by
Christian Huelsmeyer in 1904. The German scientist demonstrated the possibility of
detecting metallic objects at a distance of a few kilometres. While many basic principles of
radar, namely using electromagnetic waves to measure the range, altitude, direction or
speed of objects are remained up to now practically unchanged, the user requirements and
technologies to realise modern radar systems are highly elaborated....
The action of the Royal Society at its meeting in London on November 6,
in recognizing Dr. Albert Einstein's “theory of relativity” has caused a
great stir in scientific circles on both sides of the Atlantic. Dr. Einstein
propounded his theory nearly fifteen years ago. The present revival of
interest in it is due to the remarkable confirmation which it received in
the report of the observations made during the sun's eclipse of last May
to determine whether rays of light passing close to the sun are deflected
from their course....
The advent of novel materials for electronics, optoelectronics and nanoelectronics holds the
promise for new microelectronic device designs and applications across all fields of science
and technology. Furthermore, the increasing sophistication of fabrication processes and
techniques used in the semiconductor industry has resulted in the ability to produce circuits
of greater complexity at remarkably reduced costs, a trend which has been continuing over
the past half-century.
Larry Bachus and Angel Custodio met each other in the early 1990s in
Puerto Rico. Larry was working on a pump and seal conversion in a
pharmaceutical chemical plant and Angel was installing a computerized
preventive maintenance system in the same plant. They had passed each
other in the administrative offices at the plant and one day the
maintenance engineer introduced them and suggested they work
together. They became fast friends and have worked together on
numerous projects over the years since, including this book....
can be done on a test rig out in the main works or sometimes even on the equipment while running normally. However, the basic idea is that pitch, profile and helix errors may combine with tooth bending, gear body distortions and whole gear body deflections to give an overall relative deflection (from smooth running) at the meshpoint between the gears. It is also difficult to convince gear engineers that there is a very big difference between roll (double flank) checking, which is extremely cheap and easy, and T.E. (single flank) checking since they give rather similar looking results.
'People skills' are now recognised as being THE single most important factor for success in business. Managing Yourself is a practical, easily absorbed and implemented guide to the assessment and then continuous personal improvement of your emotional intelligence. It provides the reader with easily understood and workable models of how they think, feel, relate to others and perform in the workplace. Often your emotions hold you back or deflect you off course. This book shows you how to master your emotions and get the results you deserve.
Steady and Impulsive Vibratory Stresses
For steady vibratory stresses of a weight, W, supported by a beam or rod, the deflection of the bar, or beam, will be increased by the dynamic magnification factor. The relation is given by dynamic = Static x dynamic magnification factor An example of the calculating procedure for the case of no damping losses is »„ - S^ Xi _(^)2 (10.65)
In general, it is the BEV (not the )V) that describes the VTV crash severities in a complete manner. Only in the fixed barrier test condition or when the stiffness ratio equals the mass ratio, will BEV (or crash severity index) be the same as )V (or crash momentum index). This relationship can be proved by simply making Rm = Rk and substituting into Eq. (7.52). Then BEV1/Vclose = )V/Vclose = 1/(1+Rm). 7.6.3 Crash Severity Assessment by a Power Curve Model This section presents a model with power curve force deflection, as shown in Fig. 7.28. The model is used...
