Understand, Optimize, and Control Your Multi-Physics System with Simulation Software

Technical systems, like machines and manufacturing plants, are often very complex. They consist of a multitude of components and subsystems, usually based on diverse technical domains and increasingly fitted with sensors and controls. Their dynamic interactions have a significant impact on safety, performance, and comfort, raising questions:

  • Which is the best layout and operation/control strategy of my hybrid powertrain in terms of energy efficiency and performance?
  • Which vibrations generated by the engine and transmitted via the drive train reach the seat rail?
  • How long does it take for my air brake system from the pedal being actuated until the desired braking force is applied? What pressure is applied to the brakes? And how much air is consumed?
  • How can renewable energy sources, storage, electric mobility, and consumers best be integrated so that demand can always be met? What storage sizes are needed, and how to control them?
  • How can I ensure that my machine/plant meets the requirements for safety, reliability, and functional quality even under the influence of manufacturing tolerances, failures, wear, and aging?

System simulation is created to efficiently model, simulate, and analyze arbitrary machines and plants' behavior. It is used in a multitude of industries and applications such as vehicles, construction & industrial machinery, energy systems, aerospace, medical technology, and consumer devices, to name a few.

SimulationX for Mobile Machinery

With such a vast amount of requirements, accurate analyses of transient, nonlinear processes are becoming increasingly vital. For such considerations, it is usually not enough to only look at stress analyses, flow calculations, or cinematic simulations. Mobile machines like excavators, wheel loaders, agricultural and forestry machinery, road construction equipment, concrete mixers, concrete pump systems, cranes and hoisting gear, compression, and tunnel boring machinery are mechatronic systems. Besides mechanical parts, they consist of hydraulic actuator systems and the corresponding control units. Many undesirable effects during operations have their cause in a weak interaction of the sub-systems from various physical domains. Especially the high number of nonlinear processes in mobile machinery is hardly manageable through measurements alone any longer.
