Definitions

  • This device has means for, in particular automatically or semi-automatically, executing at least one variant of the method according to the invention. These means can in particular be the means described in connection with the data processing device mentioned.
  • the device according to the invention can have a corresponding processor, a data memory and at least one input and / or output interface for executing the method or the corresponding computer program or program code.
  • the device according to the invention can comprise the computer program product according to the invention. Since the device according to the invention can therefore in particular be set up to carry out the method according to the invention and the method according to the invention can thus be carried out by means of the device according to the invention, the device according to the invention can correspondingly some or all of the properties and / or or have features.
  • FIG. 3 shows a schematic representation to illustrate a second description of the component
  • FIG. 4 shows a schematic representation to illustrate the digital representation.
  • Knowledge of the surroundings of the respective technical structure can advantageously also be taken into account in order to ultimately simulate the behavior of the respective specific configuration of the technical structure in a specifically provided operational or work environment.
  • the individual components are modeled on a domain-specific basis, in particular on the basis of the respective digital 3D geometry data provided. If necessary, several domain-specific models of different domains can be generated or provided for a single component, but these can each be based on the same 3D geometry of the component. In each case, dimensions according to the design or specification can be used for the geometries or corresponding 3D geometry data, so that the components are not simplified or abstracted here with regard to their geometry or with regard to their structure, which ultimately enables improved accuracy of the resulting results to be achieved .
  • Surrounding components or surrounding elements that is to say elements or parts of the surroundings or those that represent the surroundings, can be provided or represented in the same way or, if necessary, by simplified or idealized elements.
  • This CAE-compliant preparation can already be seen as the first part of a model order reduction, through which the amount of data to be handled and a corresponding calculation or simulation effort is reduced or limited to such an extent that the method described here can be used with conventionally available calculation hardware, for example conventional workstation computers or Workstations, and no mainframes or supercomputers have to be used.
  • the modal analysis and the model order reduction are carried out for all components of the respective technical structure, in this case for all components of the HV motor.
  • respective eigenmodes are used for the bidirectional connection of an inner modal description and an outer Cartesian description. Like the respective natural frequencies, these are an integral part of the modal analysis and therefore do not require any additional calculation effort.
  • Cartesian and modal coordinates (modes) are only converted here at the observation points, so that ultimately an external effect of the respective component or the respective technical structure or system is only calculated there. The calculation is carried out using the eigenform matrix f.
  • the modes map k states of the respective system, which are summarized in the state vector q (t).
  • method step S5 i.e. corresponding state space matrices
  • method step S6 preferably in a neutral format, into a system simulation, that is, corresponding software or a corresponding program, for example "Ansys Twin Builder"
  • a system simulation that is, corresponding software or a corresponding program, for example "Ansys Twin Builder”
  • component twins are assembled to form the digital representation of the entire technical structure.
  • the component twins are connected to one another, whereby further elements can be added if necessary and the composite of components into its planned Target application, i.e. a corresponding operational or working environment, can be used.
  • the composite of components into its planned Target application i.e. a corresponding operational or working environment
  • environmental, boundary and initial conditions can be defined and modeled.

Abstract

La présente invention concerne un procédé assisté par ordinateur (1) et un dispositif (C1) de génération d'une représentation numérique (17) d'une structure technique, en particulier un moteur électrique, et un produit-programme d'ordinateur correspondant (1, C2). Dans le procédé (1), des modèles spécifiques au domaine sur la base de données géométriques numériques de composants (2, 18, 19, 20, 21, 22) sont fournis, et sur la base de ceux-ci, une réduction d'ordre de modèle est effectuée, les modèles spécifiques de domaine étant convertis en coordonnées modales qui sont utilisées pour déterminer un comportement spectral des composants (2, 18, 19, 20, 21, 22) à l'aide d'une analyse modale respective. Sur la base de celles-ci, des représentations d'espace d'état correspondantes sont générées en tant que modèles spectraux à ordre réduit. Afin de simuler la structure technique dans son ensemble, les modèles spectraux sont couplés ensemble pour former la représentation numérique (17), qui décrit le comportement de la structure technique à travers des domaines, afin de produire une simulation.
