Simulation in the Automotive Industry

Testing and simulation in vehicle development ensure proper functionality of your systems. Are you looking to model transmissions, chassis and vehicle dynamics, for instance, in order to develop vehicles that are more energy efficient? Then SimulationX is your simulation software of choice.

Testing and simulating different functionalities in vehicle development

Be it modeling of drive systems, chassis and vehicle dynamics simulation, efficiency analyses of gearboxes or energy efficiency in general – ESI ITI’s engineers support you throughout the entire product development process. Model your own multiphysics systems and conduct virtual tests in SimulationX. System integration is our core competency; achieving proper functionality is our common development goal; system simulation with our simulation software SimulationX is your tool of choice.

New in SimulationX 3.8
  • Evaluate complex three-dimensional rope and belt drives through detailed and convenient simulation

    Operating complex rope and belt assemblies with high precision including offshore heave compensation requires accurate controls and clever engineering. With the new, dedicated model library with pulleys, drums and belts/ropes, you can create detailed models of spatial rope and belt drives or winders for cables and wires fast and efficiently. Evaluate all interactions between belt or rope, input, output and controls as well as occurring forces and torques.

  • Evaluate the influence of humidity in air and other gases in air conditioning systems or industrial processes

    In HVAC systems and many manufacturing processes, the right humidity level is crucial for the human comfort or the product quality. Furthermore, the heat balance of thermal systems, for example in air coolers or condensing boilers, is influenced if vapor inside the air or gas condensates.Gases and mixtures in SimulationX can now incorporate humidity. Get reliable information about the condensing behavior of thermal systems based on accurate simulation results!

  • Ensure safety and comfort during braking maneuvers of cars and motorbikes (including influences of ABS and ESP)

    The new, dedicated model library Hydraulic Brake Systems helps speed up the development process for brake systems. Analyze resulting forces at the wheel brake cylinder and the “pedal feeling” during braking maneuvers with comprehensive system simulation. Use the ready-made, detailed braking component models for evaluations of braking comfort and for analyses of the vehicle’s overall behavior (e.g. stability during braking or ABS/ESP intervention).

  • Design reliable lubrication systems inside engines and gearboxes

    Simulate the oil-circulation system for lubricating combustion engines and gearboxes with SimulationX and the new model library “Hydraulic Lubrication”. Examine whether the chosen design provides sufficient lubrication at the desired bearings with respect to heat input, heat transport and other influencing factors.

  • Simulate electric machines, which serve as generator or motor, without the need to have detailed knowledge in electrical and controls engineering

    With dedicated circuit models, which are easily parameterized with catalogue data and the desired automatic controller action, design engineers can simulate the behavior of electric machines interacting with mechanical and electrical components. Electrical engineers benefit from ready-to-use circuit models for efficient and easy modeling, simulation and detailed analyses of the power electronics and controls in electric machines.

    Automotive engineering: market requirements and trends

    When computers and machines in today’s digital factories take over more and more development and production tasks, the engineer’s abilities to make assessments and to handle integrated systems are key. Instead of looking at isolated systems, such as the chassis, engine, transmission or clutch, engineers are forced more than ever to recognize correlations and think in more integrated ways. Here are some examples of the ongoing change in the automotive industry:

    • Strong division of labor between internal resources and external suppliers at different locations around the globe
    • Great share of development work with shorter development cycles
    • Declining product maturity due to time constraints, while more variants are explored in the development
    • Integrated development and production units
    • Increased complexity by transition to mechatronic vehicles
    • More safety regulations and standards

    Quality management in vehicle development

    Already 90 % of all innovations in vehicles involve electronic systems – with a growing tendency. What do your development engineers contribute to ensure proper functionality of your products? What is your development approach? How can you further improve quality and the development process? How do you counter hazards and risks? The ISO standard 26262 does not suffice today’s methods in product and quality management. We have the necessary experience from many different projects and know our way around finding the right solution for you.

    Our solution

    Simulation solutions for the automotive industry

    What may the drivetrain in future vehicles look like? How high are power density, energy efficiency, flexibility, vehicle dynamics and driving comfort? How do several physical systems interact with each other and how can mechatronic correlations be described in a comprehensible way? These and other questions can no longer be answered through measured data. That is why renowned car makers around the globe have been working in their product development with one of the leading simulation tools and engineering services from ITI for years: SimulationX.
