Previous years’ Technology Days have focussed on durability, reliability and associated data analytics of in-field, proving ground and laboratory vehicle testing (hosted in 2020) and fatigue testing, characterisation and simulation of traditional and additive manufactured material, surface treatments and joints & welds (hosted in 2021). Both the presentation recordings and downloadable content is available to access below.
Understanding and characterising battery performance is critical for electric vehicle development. This learning is established from multiple sources including laboratory testing, real-world vehicle fleets, physics and chemistry simulation models, and statistical and machine learning models.
These presentations describe predictive battery analytics, characterisation of lithium-ion cells and measuring battery capacity fading using force transducers.
Testing electrical machines and electrical powertrains is a key task in developing the electric future of industry and transportation. To increase efficiency, acoustic quality, durability and reliability of next-generation electrical machines and drives, used in cars, other land vehicles, air vehicles and marine vehicles, requires testing with accuracy and precision, and analysis capability to characterise their steady state and dynamic operational conditions.
These presentations describe using electrical characteristics to identify motor degradation and failure, acoustic quality at end-of-line testing, efficiency characterisation by instantaneous power calculations.
Civil infrastructure (bridges, tunnels, railways, pipelines, energy plant, process plant) are subject to operational environments and conditions that cause structural degradation through time, normal use, extreme use, accident, and potential natural disaster. Structural health monitoring (SHM) is the ability to measure and observe the response of a structure to enable early identification of deterioration through response changes.
These presentations show the value of information from SHM for emergency management, bridge inspection requirements, research for bridges as a population of structures, and optical sensor technology used in measurements for SHM systems for bridges and civil infrastructure.
The value of structural health monitoring (SHM) is realised through analysis of structural response measurements. Such analyses can include structural characterisation, identification of trends and divergence from trends, calculation of cumulative usage indicators, predictive estimation of remaining structural life and more. These data analytics quantify the overall structural condition to inform decision making for continual safe operation, predictive maintenance planning, and replacement planning
Successful and efficient implementation of SHM data analytics requires many steps from measurement data acquisition, validation & cleaning, database ingress, calculating operational parameters from physical and statistical models, investigative and retrospective analysis, visualisation and reporting.
These presentations show applications of such models with machine learning for SHM of bridges and civil infrastructure, certification of machine learning for remaining useful life of aircraft landing gear, and SHM of railway infrastructure and rail vehicles.
The increasing electrification of transport systems presents many challenges to achieving the desired reliability of these electric vehicles and their electric power systems, to mitigate both a safety risk and warranty exposure. They require convergence and conversion between mechanical power and electrical power. Some failure modes and reliability models carry over from predominantly mechanical powered vehicles, whilst new failure modes are created, requiring identification and quantification through testing, simulation and validation.
These presentations show building a reliability validation plan for the automotive electric powertrain, statistical and reliability methods for determining electric vehicle system reliability, and why aviation needs more reliable and standardised electrical testing for the shift to more-electric aircraft.
Fault tree analysis is one of many symbolic analytical logic techniques found in operations research, system reliability analysis, risk analysis and other disciplines. A fault tree diagram follows a top-down structure and represents a graphical model of the pathways within a system that can lead to a foreseeable, undesirable loss event (or a failure). The pathways interconnect contributory events and conditions using standard logic gates (AND, OR, etc). Analysts may wish to use fault trees in combination with reliability block diagrams for system analysis. Fault trees may also be useful for analysing the effects of individual failure modes and in conjunction with FMEA.
These presentations introduce fault tree analysis to identify the critical path, and their use in combination with reliability block diagrams to understand and improve a system, followed by their application to tens of thousands of assets for advanced reliability analysis and reliability digital twins.
