Hoses and tubing - Applications and improvements

Different types of tubes, hoses or grommets are used, for example, to transmit hydraulic pressure, negative pressure or coolant. These include air intake hoses, coolant hoses, fuel hose, brake hose or the engine control unit (vacuum and overpressure hoses).
Worn or torn hoses can leak, which can have a negative effect on vehicle functionality.

These hoses are affected by a natural ageing process and therefore have a limited lifecycle. The selection of components must be adapted to the respective application. The hose resistance, temperature range and bending radius play a decisive role in the application duration of the hose system.
These products are regarded as safety-critical parts and therefore play a decisive role in the development of vehicles and components.

In order to take all these aspects into account in the 3D mechanical design of various hoses and tubes in modern vehicles, IPS Cable Simulation provides the real-time capability for this task and helps engineers to obtain reliable results without long iteration cycles or extensive prototyping.

Sensor cable and brake hose under dynamic effects in the suspension

The dynamic behaviour on cables and hoses can play a decisive role in the suspension (sensor cable or brake hose). ... See more

Rapid changes in motion or high frequencies based on excitation during compression and rebound in the suspension can result in dynamic effects that can be simulated with the dynamic module after the quasi-static design in IPS.

As a result, the user receives a virtual validation of dynamic influences on flexible components to examine the layout, design space and durability in order to reduce hardware prototypes.

Engine hoses – Mechanical behaviour

This design project was concerned with the ideal length of hoses in the engine compartment, which is necessary to analyze the stress during engine movement. ... See more

For this purpose, the CAD model of the vehicle was loaded into IPS Cable Simulation, the hoses were automatically flexibilized using the specified connection points and the kinematic movement mapped. The hose lengths were varied and the respective stress was displayed by the software in real time. Thus the optimum length could be successfully determined. In addition, material stress and installation space requirements were reduced considerably, since IPS Cable Simulation can be used to determine the optimum routing with the fastening points for clips and hose guides.
