RISTop-Down Hierarchical Construction and Application of a Domain Knowledge Graph Based on Multimodal Design Information
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Market demands for diversified and personalized customer needs drive the need for continuous high-speed iteration of products. Among them, product conceptual design is the core process for meeting consumer needs and ...
Coarse to Fine Extraction of Free Form Surface Features
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Freeform surface features (FFSFs) extraction is one of the key issues for redesigning and reediting the surface models exported from commercial software or reconstructed by reverse engineering. In this paper, a coarsetofine ...
Finite Element Method and Sharp Features Enhanced Laplacian for Interactive Shape Design of Mechanical Parts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Laplacian based model editing is one of the most popular shape modification methods for product design. However, most existing Laplacian based methods suffer shape structure and saliency feature distortion, which limits ...
A Novel Region-Division-Based Tolerance Design Method for a Large Number of Discrete Elements Distributed on a Large Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The array structure is widely used in precise electronic products such as large phased array antennas and large optical telescopes, the main components of which are a large surface base and a large number of high-precision ...
A Novel Method of Designing Random Rough Surface Considering Its Contact Force–Deformation Characteristic Requirement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The height probability distribution (HPD) of random rough surface topography has significant effect on its contact behaviors. In this paper, an optimization model to calculate the optimal HPD of random rough surface ...
A New Sequential Sampling Method for Surrogate Modeling Based on a Hybrid Metric
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Sequential sampling methods have gained significant attention due to their ability to iteratively construct surrogate models by sequentially inserting new samples based on existing ones. However, efficiently and accurately ...
A New Validation Metric for Models With Correlated Responses Using Limited Experimental and Simulation Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Model validation is the process of determining the degree to which a model is an accurate representation of the real object. Most of the existing model verification metrics rely on massive data, which are expensive to ...
Toward a Digital Twin: Time Series Prediction Based on a Hybrid Ensemble Empirical Mode Decomposition and BO-LSTM Neural Networks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Precise time series prediction serves as an important role in constructing a digital twin (DT). The various internal and external interferences result in highly nonlinear and stochastic time series. Although artificial ...
Fatigue Analysis of Spherical Contact Subjected to Cyclic Elastic-Plastic Normal Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surface fatigue resulting from cyclic contact loading is a main reason for the rough surface wear. Since a rough surface consists of many asperities, the fatigue in one asperity is investigated. The multiaxial Fatemi–Socie ...
