A system, apparatus, and method of determining a condition of at least one bearing in a system are provided. The method includes receiving operation data associated with the system from one or more sensing units associated with the system and determining an operation profile of the at least one bearing from the operation data. The operation profile includes a vibration response, a thermal response, and/or a frequency response associated with the at least one bearing. An impact force profile is determined during operation of the at least one bearing based on the operation profile and a virtual bearing model trained on operation profiles and impact force profiles associated with a group of bearings comparable with the at least one bearing. The condition of the at least one bearing is determined based on the impact force profile.

A component of the technical system, a component designation and a characteristic parameter designation for a characteristic parameter of relevance to the design of the components are read and a search engine is queried with same is provided. The documents found by the search engine are read and component information, e.g. product information concerning a specific component, is extracted from said documents. The extracted component information is supplied to a machine learning routine which has been trained, using a plurality of predefined training component information and training characteristic parameter values, to reproduce predefined training characteristic parameter values using predefined training component information. Output data from the machine learning routine is selected as characteristic parameter values and inserted into a planning data record. The planning data record is then output to design the technical system.

Method and system for computer-aided design of a technical system

A device for compensating for vibration and/or material stress of a component of a high-voltage system filled with a viscous medium includes a piston and a housing. A first end piece of the piston may be coupled to the component of the system. A second end piece of the piston may be at least partly within the housing and enclosed thereby, enabling movement of the piston and the housing in opposite directions along an axis. The second end piece may be coupled to an inner wall of the housing by at least one spring. The piston and the housing are surrounded by the medium filling the system. A method and computer program product for computer-aided design of a device for compensating for vibration and/or material stress of a component of the system filled with a viscous medium are also provided.

A method for determining a remaining useful life of a bearing having a surface defect includes determining a defect size of the surface defect based on oscillations of the bearing. The method also includes determining, based on the defect size, at least one of the principal stresses or a contact force of the bearing caused by the surface defect. The method also includes determining the remaining useful life of the bearing based on at least one of the principal stresses and/or the contact force.
