In the development process, data collection, data processing and evaluation play a crucial role. Kistler supports OEMs at each stage of the testing process to develop state-of-the-art vehicles that consumers can enjoy safely. As the automotive industry shifts toward sustainable practices, EVs bring a whole new set of requirements to durability testing. Their weight and weight distribution differ from traditional combustion engine vehicles. Structural body components also affect the stiffness and loading condition that EVs are exposed to over their lifetime. Additionally, drivers become a much more important variable and the recharging infrastructure can influence the way they interact with the vehicle and the road. The same is true for the driver’s driving style and typical acceleration 74 MARCH 2024 pattern. Durability testing for EVs needs to take all these changes into account and collect data that enables measurement and evaluation of them. Durability testing is designed to assess the ability of a vehicle to withstand the stresses and strains of everyday use over an extended period. It simulates harsh driving conditions, extreme weather scenarios and various road surfaces to evaluate the vehicle’s structural integrity, component performance and overall endurance. The primary goal of durability testing is to subject vehicles to real-world conditions, simulating the wear and tear a car would experience over its lifetime and collecting data during the process. One of the measurements that test engineers take into account is road loads, which can be measured with RoaDyn wheel force transducers (WFTs) from Kistler. They can be used for road load data acquisition for various vehicle types – passenger cars, SUVs, trucks – and for the validation of structural integrity on component and whole-vehicle test stands. WFTs measure the forces and torques acting on the wheels during durability tests and can be integrated seamlessly into existing measurement technology, enabling efficient analysis of the applied operating loads on EVs. By providing accurate and reliable data, they contribute to the validation of durable designs, ensuring OEMs meet safety and energy efficiency requirements. Advances in digitalization and virtualization enable test engineers to process an ever-increasing amount of data from different sources, such as test data, including road load data, vehicle response to different road conditions and component-specific performance data. Thanks to simulation software, durability engineers can process and analyze large volumes of measured data on virtual models. This enables them to gain insights and make informed decisions – ultimately producing even more data for future testing. Durability engineers require dedicated data analysis software tools to process, analyze and interpret the large volumes of collected data. With jBEAM Durability, Kistler offers a data processing system that contains a comprehensive set of standardized and specialized functions for performing durability analysis, enabling engineers to process gigabytes of multichannel data, visualize data and use proven analysis methods for understanding product performance and durability. www.AutomotiveTestingTechnologyInternational.com
