RISAn Improved Test Method of LiFePO4/Graphene Hybrid Cathode Lithium-Ion Battery and the State of Charge Estimation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The state of charge (SoC) of the battery is a typical characterization of the operating state of the battery and criterion for the battery management system (BMS) control strategy, which must be evaluated precisely. The ...
Applying a Macroscopic Calibration to a Wiedemann Driver Behavior Threshold Study
Publisher: American Society of Civil Engineers
Abstract: A speed - flow graph is used to calibrate Wiedemann 74 model parameters. A parameter calibration platform integrating VISSIM, Matlab, and ExcelVBA is built, which minimizes the differences between the measured values and ...
Microtubular Hard Carbon Derived From Willow Catkins as an Anode Material With Enhanced Performance for Sodium-Ion Batteries
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As a kind of common bio-waste, willow catkin is of no economic value. But it is surprising that it can be an ideal carbonaceous source and bio-template for electrode materials of lithium-ion batteries and supercapacitors. ...
Paul-Mohr-Coulomb Failure Criterion for Geomaterials
Publisher: American Society of Civil Engineers
Abstract: Paul-Mohr-Coulomb (PMC) failure criterion provides enhanced representations of pyramidal failure surfaces, with recognizable material parameters, by considering all three principal stresses. PMC exhibits traits of more ...
Dynamic Modeling and Nonlinear Characteristics of a Cracked Bolt-Disk Combined Rotor System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Different from the crack on the rotating shaft, the crack on the bolt, which is a connecting part of the bolt-disk combined rotor, is a kind of local defect. The local crack on the bolt under high pretension is always in ...
Design, Modeling, and Evaluation of a Hybrid Driven Knee-Ankle Orthosis With Shape Memory Alloy Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper demonstrates the mechanical design, analysis, and evaluation of a knee-ankle orthosis (KAO) for lower limb rehabilitation, including shape memory alloy (SMA) actuators and DC brushless motor actuators. First, ...
Hybrid Compound Function/Subinterval Perturbation Method for Kinematic Analysis of a Dual-Crane System With Large Bounded Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: By introducing the subinterval perturbation method (SIPM), a hybrid compound function/subinterval perturbation method (HCFSPM) is presented for a dual-crane system (DCS) with large interval variables. The HCFSPM employs ...
Multidomain Synthesis of Optimal Vibration Suppression Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There are numerous design possibilities for vibration–suppression systems considering components from multiple domains (e.g., mechanical, hydraulic, pneumatic, electrical). Traditional vibration absorber design approach ...
Development and Dynamic State Estimation for Robotic Knee–Ankle Orthosis With Shape Memory Alloy Actuators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of rehabilitation robots has long been an issue of increasing interest in a wide range of fields. An important aspect of the ongoing research field is applying flexible components to rehabilitation equipment ...
How to Realize Volume Conservation During Finite Plastic Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Volume conservation during plastic deformation is the most important feature and should be realized in elastoplastic theories. However, it is found in this paper that an elastoplastic theory is not volume conserved if it ...
