Dynamic Stress Analysis of Battery Tabs Under Ultrasonic Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic metal welding is widely used for joining multiple layers of dissimilar metals, such as aluminum/copper battery tabs welding onto copper busbars. It is therefore important to have a robust product/process design ...
Dynamic Response of Battery Tabs Under Ultrasonic Welding
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ultrasonic metal welding (USMW) for battery tabs must be performed with 100% reliability in battery pack manufacturing as the failure of a single weld essentially results in a battery that is inoperative or cannot deliver ...
A Fatigue Life Study of Ultrasonically Welded Lithium Ion Battery Tab Joints Based on Electrical Resistance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fatigue life of ultrasonically welded lithiumion battery tab joints is studied for electric and hybrid–electric vehicle (EV and HEV) applications. Similar to metallic materials, the electrical resistance of these ...
Spot Weld Layout Optimization of Tube Crash Performance With Manufacturing Constraints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Spot weld layout is critical to structural performance of vehicle and its design is also subject to manufacturing constraints. In this study, using thinwalled tube crash as an example, we establish the relation between ...
A Novel Numerical Model of Ultrasonic Assisted Resistance Spot Welding Process to Unravel the Weld Formation Mechanism in Multilayer Foil Welding
Publisher: The American Society of Mechanical Engineers (ASME)
