A low-voltage switch is meant to interrupt an electrical
circuit on command, and as quickly as possible.
The lever that is shown in the lower left picture, is
the true electric contact. This lever must be moved
off the pad (not shown in the picture) with a mechanical
A strong tension spring provides the energy source:
this can be seen in the upper part of the picture. A
toggle switch system increases the lever's angular velocity,
allowing it to jump away from the pad as quickly as
The functioning of the system is triggered by activating
the handle (arrow) directly on the screen.
Aerial Cable-Railways: silux
tells you exactly what will happen when there is a crash
A Swiss firm built the first aerial cable-railway with
a two-level cabin. In this field, safety regulations
are as stringent as those that prevail in aircraft production.
The whole system must be tested for all conceivable
incidents and safety must be assured in all cases. A
possible scenario is an emergency stop directly over
a cable pylon. In this special case, rough estimates
show that the suspension of the cabin will collide with
the so-called "saddle" of the pylon. The whole
construction of the suspension has to be checked with
a finite-element program, also for this special case.
The problem is that we don't know the magnitude of the
force or the duration over which it affects the cabin
suspension upon impact. At this point, silux comes into
The program simulates not only the dynamic relationships
between all the individual parts and of the system as
a whole in every detail, but also allows for the analytical
investigation of specific forces and of other physical
Watch: With silux you
can examine the whole thing more closely
silux can process drawings from other computer programs
and computer systems. Data from external sources is
imported with a standard exchange format (DXF).
silux thus has an interface with existing CAD-systems.
Although silux provides all the functions necessary
to guarantee independant operation, silux is not meant
to replace CAD-systems. It's clear though that silux
provides considerably enhanced performance to any CAD-system.
silux provides all the tools necessary to import data,
to update it if need be and to create a working simulation
leaves (almost) nothing to chance
Let a number of marbles fall from a funnel through a
grid of rods. At each rod, the marble may fall either
to the right or to the left. The chance in a statistical
average is always the same for both sides. At the lower
part of the cascade, the marbles fall into different
rows. Following the rules of probability theory, a greater
number of marbles must appear in the middle rows.With
statistical rules and methods, you can show that a great
number of events in the statistical average forms a
Locomotive: With silux
you understand and improve what has already been done
This drawing of a stem locomotive (close to 7000 single
elements) has been imported into silux software with
the help of DXF exchange format, where it has been extended
into a functioning silux simulation program.
Fall Tower: If
you fall from the sky - silux shows you the way
how to land smoothly
If you fall from the sky - silux shows you the
way how to land smoothlyThe 146 m high fall-tower in
Bremen/Germany belongs to the University of Bremen.
The task of the ZARM (Center of Applied Space Technology
and Microgravity) is toprovide an inexpensive and quick
alternative to space flights. Scientific experiments
are put into a fall capsule and are then let drop freely
in an evacuated tube. During a flight of 4.7 seconds,
weightlessness of a very high quality is achieved. At
the end of a free fall, the capsule is stopped by an
8 m high pile of styrofoam granules. A deceleration
of 30-50 times the Earth's acceleration takes place.
Many scientific experiments are currently being carried
out all over the world insuch towers. This includes
many experiments from the field of fluid dynamics, for
example, the combustion in engines under ideal circumstances,
The current silux experiment is meant to research the
stopping procedure of the capsule in the styrofoam pile
and to compare results with experimental measurements.
The deceleration of the capsule during the breaking
procedue is investigated experimentally with different
Collision of planets: With
silux you can experience the apocalypse ... now!
The most likely theories state that the Earth's moon
was created by a collision of the Earth with another
planet. Studies of rocks from the moon have especially
supported this theory. The other planet was about the
size of Mars and hit the Earth in a grazing collision.
Some of the material that was thrown up fell back to
Earth. Other material got into orbit around the Earth
and created the moon. It is also possible that the left-over
material from this collision formed the asteroid belt.
This expanse of rubble islocated between the paths of
Mars and Jupiter.

"Perpetuum mobile" means perpetual motion in
Latin. Perpetuum mobile are machines that people devised.
The makers of these machines thought that the moveable
parts of the machine, once put into motion, would never
stop. They even hoped to accomplish additional work with
these machines. This sort of perpetuum mobile would be
called a motor in today's terms: a motor that perpetually
turns without an additional supply of energy.
Leonardo da Vinci worked through the question of these
machines thoroughly but apparently realized quite quickly
that such machines are not possible.
One-legged hopper with telescop spring
The idea for the one-legged hopper came from the following homepage: www.cim.mcgill.ca ARL, Ambulatory Robotics Laboratory, Center for Intelligent Machines, McGill University Montréal, Québec, Canada.The monopod robots mentioned in this source serve as platforms for examining control mechanisms during so-called "passive dynamic hopping".silux was used to examine the same type of problem with a virtual robot model. Various control functions were simulated with silux and comparisons between control systems and robot behavior were made.
