Variation Simulation of Stresses Using the Method of Influence Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In every manufacturing situation there are geometric deviations leading to variation in properties of the manufactured products. Variation affects the manufacturability, functions and aesthetics of the products. Therefore, ...
Efficient Spot Welding Sequence Optimization in a Geometry Assurance Digital Twin
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A digital twin for geometry assurance contains a set of analyses that are performed to steer the real production for securing the geometry of the final assembly. In sheet metal assemblies, spot welding is performed to join ...
Combining Variation Simulation With Thermal Expansion Simulation for Geometry Assurance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In every set of assembled products, there are geometrical variations and deviations from nominal dimensions. This can lead to products that are difficult to assemble or products not fulfilling functional or aesthetical ...
Using Morphing Techniques in Early Variation Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Today, in order to be competitive in a fierce global car market, higher demands are placed on the perceived quality (PQ) of the products. The end customer's visual impression of fit and finish are one of several factors ...
Efficient Contact Modeling in Nonrigid Variation Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Virtual tools and methods are becoming increasingly important in order to predict the geometric outcome in early phases of the product realization process. Method of influence coefficients (MIC) in combination with Monte ...
Minimizing Weld Variation Effects Using Permutation Genetic Algorithms and Virtual Locator Trimming
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mass production paradigm strives for uniformity, and for assembly operations to be identical for each individual product. To accommodate geometric variation between individual parts, tolerances are introduced into the ...
Efficient Compliant Variation Simulation of Spot-Welded Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During product development one important aspect is the geometric robustness of the design. This is due to the fact that all manufacturing processes lead to products with variation. Failing to properly account for the ...
Efficient Joining Sequence Variation Analysis of Stochastic Batch Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Geometric variation causes functional and aesthetic problems in the assemblies. The challenge is predicting the moments of the distribution of geometric deviations of assemblies to evaluate compliance with the set requirements. ...
Efficient Spot Welding Sequence Simulation in Compliant Variation Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Geometrical variation is one of the sources of quality issues in a product. Spot welding is an operation that impacts the final geometrical variation of a sheet metal assembly considerably. Evaluating the outcome of the ...
Variation Simulation of Welded Assemblies Using a Thermo Elastic Finite Element Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Every series of manufactured products has geometric variation. Variation can lead to products that are difficult to assemble or products not fulfilling functional or aesthetic requirements. In this paper, we will consider ...
