Usage of FEA to determine the vibration behavior of the base plate Hall 8
Sascha Döhler Engineer Framag Industrieanlagenbau GmbH AUSTRIA
Test benches are placed on base plates that are decoupled from the ground. Therefore, the base plate is a very important part of every test bench. Test devices, frames, dynos, motors and more are directly connected to the base plate. The static, dynamic and vibration behavior of the whole test bench is significantly influenced by the base. This means that the performance of a test bench is influenced by the mass, stiffness and damping properties of the base plate. This presentation will show how numerical tools can be used to observe and improve the static and dynamic behavior of base plates for test benches.
Source characterization using blocked forces and experimental dynamic substructuring Hall 8
Dr Dennis de Klerk Managing director Müller-BBM VibroAkustik Systeme BV NETHERLANDS
Vehicle development processes require a more modular approach in NVH engineering where simulation and testing merge. Experimental dynamic substructuring introduces a new era for testing, as measurements may serve as an input to simulation rather than a validation process. Depending on the component complexity and the prototype availability, a component model is generated either from simulation (FEM model) or test (test-based model). Experimental substructuring combines all component models to obtain a virtual acoustic model of the vehicle from, for example, the driveline components up to the driver's ear.
Digital ADAS – camera and radar calibration
Andrea Cantadori Head of engineering and product management Mahle Service Solutions Europe Mahle Aftermarket Italy SpA ITALY
ADAS (advanced driver assistance systems) technologies can detect and classify various objects, inform the driver of dangerous road conditions and, in some cases, apply the brakes or bring the vehicle to a stop. Installation is increasingly no longer limited to higher class vehicles. ADAS is a combination of different sensors, cameras and software. This complex network of vehicle systems must also be recalibrated during routine maintenance work to ensure that ADAS functions are all ready to run. With Mahle's intuitive, future-proof TechPRO Digital solution, ADAS is setting new benchmarks in maintaining and calibrating these driver assistance systems.
Sensor data analytics to support predictive maintenance Hall 8
Thomas Kemmerich Technical software expert HBM Prenscia GERMANY
IIoT uses sensors to gather information for the understanding of usage, maintenance and operations. A Health and Usage Monitoring System (HUMS) monitors the health state of a fleet of vehicles; it also monitors the usage and targets the improvement of its availability, reliability and performance. This presentation will describe the practical use of descriptive and predictive analytics in an industrial case study, where an automotive component is monitored. This case study required the collection of usage data off the vehicle such as digital bus data, vibration, temperature, strain, etc. The challenge is to turn measured data into actionable knowledge.

Cloud-native test automation Hall 10
Pete Staples CEO Blue Clover Devices USA
Everyone attending Automotive Testing Expo subscribes to the importance of testing, especially when 2-ton vehicles are traveling at lethal speeds. A core problem is that the people designing the tests are often disconnected from the people doing the tests. This problem can be mitigated by using test automation. This type of solution has long been very expensive and hard to apply when the production volumes are measured in thousands instead of millions. Today is possible to leverage open-source software, cloud-native infrastructure and off-the-shelf hardware to do robust test automation for about one-tenth the cost of competing methods.
Cover all angles of sensor validation Hall 10
Edward Levack Product engineer OxTS UK
ADAS test engineers need reliable reference data for the position, range and field of view of multiple sensors on their test vehicles. This process can often be time-consuming given the number of sensor configurations on Level 3 or Level 4 vehicles. This presentation will outline a new method for validating up to 12 sensors on a test vehicle at once, each sensor having an individual range and field of view configuration. Using this method, test engineers can measure target range and visibility in real time, removing the need for expensive, complicated post-processing techniques.

Aerodynamic testing and aero research challenges in Formula 1 Hall 10
Willem Toet Senior manager and professor Sauber Aerodynamics Ltd and University of Bolton SWITZERLAND
The presentation will provide a summary of how aerodynamic testing is done in Formula 1 from concept to detailed research. Aerodynamic research had been moving toward CFD combined with full-scale, high-speed wind tunnel testing until rules put the brakes on CFD (or so it seemed) and eliminated full-scale wind tunnel work. So teams found ways to conduct effective research within these restrictions. The results are clear for all to see. For example, limiting CFD computer power has led to better software, and model tests have become races against the clock. A glimpse into the dark arts!
Innovative testbed solutions for thermal management Hall 10
Peter Drage Global business segment manager thermal testbeds AVL List GmbH AUSTRIA
Vehicle thermal management is widely accepted as one of the key development topics for future vehicle concepts, as it directly influences the vehicle range, component lifetime and passenger comfort. Huge effort goes into optimizing development processes to implement innovative solutions focusing on coupled CAE methodologies as well as interactive testing approaches. One drawback when it comes to front-loading during development is the inability to perform certain development and validation tasks on a testbed rather than in the vehicle itself. This presentation focuses on testbed solutions for thermal management applications that close the gap between virtual development and physical validation by taking into consideration the best of both worlds. These testbeds comprise highly dynamic conditioning units that are controlled via customer-specific CAE tools and thermally emulate heat sources like ICE or battery, or heat sinks such as single radiators or the entire cooling system of an engine. It will be shown how CAE models as well as virtual prototypes can be integrated in the testbed via an independent coupling platform, and how that approach is used to fulfill validation as well as control development tasks. One example is the use of a model that is implemented in a dynamic coolant conditioning unit to emulate the cooling system of a battery while the battery – including the BMS – is tested in hardware. By means of this approach it is possible to directly test the effect of adapting, for example, radiator sizes, pump power or cooling air inlets, etc to the thermal behavior of the battery.

A new concept of brake for dynos: the hybrid hydroelectric Hall 10
Enrico Corti Founder Alma Automotive Srl ITALY
Water brakes have been used for a long time due to their compactness, low inertia and reliability. However, the control accuracy is usually an issue. Furthermore, water brakes are passive machines which cannot be used to drive the engine under test. Lately, the large majority of test brakes have been based on electric machines, which are accurate and can work in motor and generator modes but require an expensive and bulky infrastructure (dedicated powerhouse, wirings, drive system, etc). A solution based on the coupling of the two machines may be effective in terms of total cost and performance.

Hybrid testing – numerical simulation meets testing Hall 10
Stefan Kirschbichler Head of occupant and VRU safety Virtual Vehicle AUSTRIA
Hybrid testing is an innovative approach to combine testing with numerical simulation to provide cost- and time-efficient engineering solutions. We will show how this can be done on two use cases. The first use case is about an efficient approach for validating the B-pillar crash behavior by using numerical simulation to set up a B-pillar test bench as a replacement for a full-vehicle crash test. The second use case shows how numerical crash simulation can be used to extend the capabilities of active safety testing by combining them into one hybrid test.
