In order to produce vehicles cost-efficiently, manufacturers are increasingly using a common-part strategy across platforms when developing their model range. Röchling Automotive takes this approach into account and supports OEMs with internally developed software for designing filter elements.
Simulation of single measurements within a few hours instead of several weeks
Emissions regulations and customer requirements play a key role in the development of new filter elements. For this reason, Röchling Automotive developed a software for estimating the lifetime of filter elements, thus simplifying the pre-development of these elements in terms of filtration and pressure drop. In addition, the tool allows a comparison of different filter geometries with the aim of limiting the number of different filter elements used across platforms. The software is able to simulate single measurements within a few hours, whereas a realistic test setup using prototypes in accordance with ISO standard 5011 takes several weeks to prepare.
Number of different filters used across a model range can be reduced
The software allows a comparison of different filter geometries, making it possible to significantly reduce the number of different filters used across a model range. Within a few hours, the program provides reliable results on optimum filter design as well as filter duration and performance. For this purpose, the tool uses engine data, target values of the OEM with regard to air filter lifetime and load capacity, filter data such as paper thickness and porosity as well as vehicle-specific packaging data.
Costly real-world test environment not necessary anymore
The user can define the operating conditions under which a filter has to function. A comparison between results generated by the software and measurements provided by realistic test setups on the basis of identical conditions and parameters showed that the mathematical calculations coincide with the practical results. The high accuracy of the results makes real-world tests unnecessary and has a positive effect on development efficiency. This is why the software is becoming an important part of the design process for intake systems which facilitate a common-part strategy across OEM platforms.
