46 road-load data with the IMC WFTCx wheel force transducer, which is processed and used to control load machines within a test bench setup. Thermal and environmental testing capabilities include analogue and digital interfaces for integrating third-party test-bench components, such as environmental chambers and thermal imaging systems. IMC’s solutions can support thermal runaway testing and thermal-management system evaluations, particularly in battery testing applications. For durability testing, the company’s data acquisition systems enable long-term vibration and shock testing under simulated road conditions. This equipment supports integration with hydraulic shakers and other environmental testing setups. IMC also provides data acquisition solutions that integrate with HIL simulation tools. The data analysis software facilitates technical data processing, automating unit and sampling rate conversions, and supporting complex calculations across multiple channels and large datasets. The company emphasises that integration with external databases, Python and Microsoft Office software enhances analysis capabilities, and custom algorithms can be incorporated to meet specific user needs. Sound measurement GRAS Sound & Vibration, also part of Axiometrix, focuses on precision acoustic data capture, offering microphones that support testing of small, electric motors to large powertrain systems. These solutions integrate GRAS’s EQset microphones, which support automated calibration, into customised test setups, ensuring reliable and repeatable measurements. For performance and efficiency testing, the company’s Ultra Thin Precision (UTP) microphones are used to capture high-frequency noise and vibration data, crucial for analysing motor efficiency across varying operating ranges. UTP microphones also facilitate harmonic analysis and transient behaviour capture, both of which are essential for motor optimisation, when integrated with advanced analysers. When used alongside dynamometers, GRAS microphones contribute to simulation of real-world conditions such as varying road gradients and regenerative braking. These microphones are designed to operate under extreme environmental conditions, maintaining performance in high-temperature and high-humidity environments, supporting detailed acoustic analysis during cooling simulations for both liquid- and aircooled motor setups. Additionally, GRAS microphones detect noise and vibration anomalies during thermal runaway testing, aiding thermal management evaluation. For NVH testing, GRAS highsensitivity microphones, such as the 146AE, capture intricate acoustic data necessary for refining motor and powertrain designs, and they are engineered for long-term durability testing under simulated road conditions. They are also built to meet stringent standards for EMI and EMC testing. The equipment integrates with simulation tools such as HIL systems to help reduce development time. The company’s real-time data acquisition and advanced analytics capabilities provide insights for predictive maintenance and design optimisation.
