The entire Transportation & Mobility(T&M) industry is in revolution: Customers are demanding new & customized experiences. New companies and competitors are emerging at a rapid pace. Electric, connected, and autonomous vehicles are beginning to enter the market with many others on the drawing board. Regulatory requirements for energy consumption, safety, and sustainability in the global marketplace are growing. Complexity is increasing. Cost pressures are greater than ever.
How is a company to compete? Digital engineering is at the core of the strategy to meet these challenges, including virtual testing and simulation in every aspect of vehicle concept, design, engineering, manufacture, and use. An industry process approach in which multiscale-multidisciplinary simulation powers discovery, innovation, and optimization to get to the market quickly – with predictable cost, reduced risk, and an exciting product that consumers want – is essential for incumbents and disruptors alike.
Driving the T&M Industry
The Worldwide Harmonized Light Vehicles Test Procedure (WLTP) determines not only how to evaluate vehicle emissions and consumption but has also expanded to include how to report expected range for electric vehicles. With the simulation solution offered by SIMULIA, OEMs and suppliers can optimize vehicle and component designs in order to meet the more stringent limits on emissions. Virtual testing is allowed as a substitute for physical testing in WLTP, and SIMULIA expertise helps users to set up a WLTP compliance regime that will be approved by the regulator.
The pace and challenge of electrification is accelerating. Whether an existing enterprise serving the Transportation & Mobility industry or a disruptive newcomer, it is impossible to succeed in the world of Electric Vehicles without the knowledge and know-how of simulation and a unified approach to developing and validating these complex interconnected systems—from batteries to electric drives, while taking into consideration vehicle architecture and driving experience.
Over the last decade, crash test regulations have become more stringent, requiring a higher level of performance to achieve a good safety rating. OEMs needed to increase the study of the structure, materials and restraint systems in order to achieve five star ratings again and this is where crashworthiness simulation plays a vital role.
Solution Capabilities for the T&M Industry
Electric Drive Engineering
Multiphysics simulation enables engineers to predict and verify the system performance across multiple design objectives and in all possible operating scenarios. Finding the best trade-offs for competing requirements like electromagnetic performance, durability, noise and vibration control, as well as lubrication requirements is a challenge, best to solve in a collaborative environment.
Address a range of engineering objectives through simulation on a digital platform to meet the vehicle occupant’s thermal, acoustic, visual, and ergonomic comfort levels. Provide a holistic cabin experience to customers while controlling energy consumption.
Performance Driven Architecture
The Performance Driven Architecture Industry Process enables early design performance assessments across different disciplines to be brought together in a common environment that fully supports requirement capture, architecture definition, system modeling and virtual simulation. Architects and simulation experts can better work together to virtually evaluate their ideas, converging quicker to better trade-offs at conceptual level before moving to detailed design.
Develop, optimize and validate typical vehicle dynamics performance criteria such as handling, driveability, and ride comfort using offline and real-time Multi Body System (MBS) simulation. This also includes advanced MBS simulation related workflows for durability assessment, component and system-level noise and vibration studies as well as the validation of the overall mechatronic system experience.
Powertrain Strength, Durability & Vibration
Powertrain Strength , Durability & Vibration is a process enabling unified end-to-end workflows of internal combustion powertrain structural simulations, with high efficiency even for very large models. This is a crucial piece of the engineering process of developing and optimizing powertrains of cars, trucks or any other vehicle containing an Internal Combustion Engine (ICE) thanks to virtual validations of their structural performance using Abaqus Finite Element Analysis (FEA) technology.
Chassis & Suspension Strength, Durability & Vibration
Key objectives of Chassis & Suspension Strength, Durability & Vibration are 1) to guarantee the structural integrity of the vehicle chassis and suspension for supporting the vehicle body, 2) to improve the ride and handling of the vehicle and 3) to make sure that the vehicle meets all the regulation and quality requirements.
Brake System Engineering
The simulation reproduces 3D physical effects of stress, heat, and fluid flow in the interactions with other vehicle systems such as controls and suspensions. The simulations with high fidelity physics based model and fast turnaround methodologies allow the engineers to quickly assess large sets of designs and improve the design. Design and validation work can be done at the full vehicle and at the subsystem levels.
Batteries are the new fuel tanks in electric vehicles. They need to store as much energy as possible to minimize range anxiety, as well as maintain safety in case of unexpected events. Batteries are highly complex systems, requiring advanced engineering methods at all levels: from chemistry to cell engineering, to module and pack engineering, and finally integration into full vehicles.
Vehicle Thermal Management
As part of automotive design, thermal management design has become increasingly important particularly due to regulations mandating higher vehicle energy efficiency to meet stricter environmental standards. An optimized thermal design results in lower emissions.
