Hi, I am Philippe from Siemens PLM Software
Since several years, design of flexible hose, pipes and cables has become more and more important.
Flexible hoses are present everywhere in modern cars,
trucks, helicopters, airplane and heavy machinery.
The challenge in designing such pipes
is to reduce, as much as possible, the time to market
and also to avoid product recalls because these
present a huge cost in terms of money and also in terms of branding image.
Siemens PLM Software has now a solution to address
this highly technical challenge: LMS Samtech Tea Pipe.
This professional, industry-oriented and industry-validated tool
is a combination of a powerful Graphical User Interface
used for defining the characteristics of the pipe
and robust Finite Element solvers that are developed now since more than 30 years by Samtech.
Actually, this is the meaning of the acronym Tea, it means: Transparent Extended Analysis.
In the past, pipes and hoses design has been ensured by using only physical prototypes
and by observing how the pipe behaves in specific working conditions.
Now, thanks to LMS Tea Pipe, it's possible to switch from this
long, costly and iterative process to a full virtual prototype.
The benefits of this virtual prototyping are multiple
and cover mandatory qualification phases of a vehicle design.
First of all, the simple to use interface, based on Siemens PLM NX Modeling,
allows the user to rapidly enter physical and geometrical data in the numerical model,
and this for a wide range of pipes, like brake cables, parking brake cables,
air/water hoses, air conditioning devices, and high pressure hydraulic lines.
Secondly, having a complete numerical model of the pipes and their environment
like the moving parts, the collision surfaces and encumbered areas,
it really increases the user's product reliability
by avoiding expensive iterations during the design phase
but it also allows the designer to explore the design space
for example, to enhance the manufacturing process
but also to master the sensitivity of the pipes' parameters
like the length, the diameter or the thickness,
but also the number and the orientation and position of the intermediate supports.
Third point, thanks to its scalability,
LMS Tea Pipe covers all kind of possible analysis
from the quasi-static mounting, in the rest position and in the kinematic positions
to the Natural mode shape computation,
and harmonic response looking at harmonic excitation in the frequency domain.
Finally, it also allows the user to have
a fully nonlinear dynamic transient response.
Scalability is also about the Finite Element hypothesis itself.
So, in LMS Tea Pipe, we have Beam hypothesis but also Shell hypothesis.
and when it comes to ovalization or even crushing of the section,
it’s very important to have this kind of simulation,
and this is often due to high flexional or torsional solicitation.
Finally, special feature like, relaxation and stiffness of intermediate support,
space-time transient temperature or pressure,
simple switch between Finite Element hypothesis,
and accessibility to advanced nonlinear analyses
helps the users of LMS Tea Pipe to define correctly their hoses
since the early pre-design phase of the vehicle
and this, without having to wait for a physical prototype.
