A vibration and noise reduction analysis device for a panel part of an automobile is configured to reduce vibration and noise of the panel part caused by vibration from a vibration source and a noise source in the automobile and identify a portion at which a weight of an automotive body of the automobile can be reduced. The vibration and noise reduction analysis device includes: an automotive body model acquisition unit; a sectioned region setting unit; a vibration and noise reduction target panel part model setting unit; a vibration mode/equivalent radiation power peak frequency selection unit; a sectioned region weight change peak frequency acquisition unit; a sectioned region weight contribution degree calculation unit; and a vibration and noise reduction and weight reduction portion identification unit.

Abstract: Systems and methods for determining cable routes of a railway infrastructure are described herein. A graphical user interface for interacting with graphical representations of railway infrastructure on a map interface is operated. A request for at least one cable route between a first position and a second position of the railway infrastructure is received. Railway infrastructure information indicative of configuration of the railway infrastructure between the first position and the second position is obtained. The at least one cable route is determined based on the railway infrastructure information. The at least one cable route is displayed on the graphical user interface.

A method of and a system for propagating a configuration setting of a 3D model to other 3D models, the 3D model and the other 3 Ds being part of a same 3D model category. The 5 method comprises dividing the 3D model into a first plurality of surfaces; associating to each one of the first plurality of surfaces, a unique surface identifier. For each one of the other 3D models, the method comprises dividing the one of the other 3D models into a second plurality of surfaces; establishing a correspondence; associating, for each one of the second plurality of surfaces corresponding to one of the first plurality of surfaces. The method also comprises 0 selecting the configuration setting of the 3D model; determining the unique identifier of the 3D model to which the configuration setting is to be applied; and propagating, the configuration setting to the other 3D models.

Systems, methods, and computer readable storage media for controlling oxidation of a particulate filter (PF) are closed. The oxidation of the PF may be controlled using a PF model. The PF model may be utilized to simulate operations of the PF based on various input data and/or derived data to determine an optimum time for initiating an oxidation event at the PF, and an oxidation event may be initiated at the PF based on the simulating.

The present disclosure discloses a model-based architecture design method for an unmanned aerial vehicle (UAV) system, which aims to deal with challenges of changeable operational requirements, shortened design period, and decreased technical risks in a current UAS design process. A data-driven architecture development method is used. By establishing an architecture development framework of the UAS, a framework modeling process oriented to different viewpoints is designed, and modeling and simulation specifications based on SysML and Modelica are defined, such that design of the UAS starts from conception and confirmation of an operational concept. The method focuses on forward analysis and design of a system framework, and concept verification and metric closed-loop are carried out at an early stage of the design of the UAS by virtue of logic modeling and system simulation.

A method for compensating springback of a part includes running a finite element analysis (FEA) simulation of forming a panel using a model of forming die such that a panel with springback is simulated, determining at least two zero springback locations on the panel where hanging apertures are simulated, running an FEA simulation of the panel hanging from the hanging apertures, and comparing a geometry of the hanging panel to a geometry of a reference panel such that a difference between the geometry of the hanging panel and the geometry of the reference panel due to the springback is determined and compensated.

A computer-implemented method for designing a product to be manufactured. The method includes obtaining a first subpart and a second subpart of the product. Each subpart is represented by a semantic representation having one or more semantic nodes. Each semantic representation has, for each semantic node of the semantic representation, a respective procedural graph and a respective semantic description of the semantic node. The respective semantic description comprises at least one semantic publication and at least one reference. The method includes assembling the first subpart with the second subpart by pointing one or more semantic references of the first subpart each to a respective semantic publication of the second subpart. The method comprises executing the procedural graphs of the semantic representations of the first and second subparts according to the pointed one or more semantic references. The method improves the designing of the product.
