考虑机构铰链非线性因素的混合键合图建模及其仿真

Jixie chuandong, 2010
As friction and clearance exist in mechanism kinematic pair simultaneously,the modeling and computation would be very complicated. A nonlinear model of the hinge is built by using switch bond graph and it is embedded into the vector bond graph modeling ...

Association between tibiofemoral bone and meniscus morphology and dynamic tibiofemoral movements during jump‐landing tasks in patients following ACL reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate whether tibiofemoral bone and meniscus morphology were associated with dynamic anterior tibial translation (ATTd) and internal tibial rotation (ITRd) during jump‐landing tasks in anterior cruciate ligament (ACL)‐reconstructed knees. Results may provide some guidance on the use of additional surgical procedures alongside (

A new cementless tibial baseplate in kinematically aligned total knee arthroplasty has low migration and stabilizes at 3 months: A cohort study using radiostereometric analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Introduction of new components in total knee arthroplasty (TKA) should be assessed for long‐term stability. The primary objective was to determine whether migration of a new cementless tibial baseplate in kinematically aligned (KA) TKA is below the 6‐month threshold where baseplates have a low incidence of long‐term loosening.

Clinical Outcomes of Kinematic Alignment Versus Mechanical Alignment in Total Knee Arthroplasty: An Umbrella Review of Published Meta‐Analyses and Systematic Reviews

Medicine Advances, EarlyView.
This is the first umbrella review that collates the evidence from 11 meta‐analyses (30 studies, 2963 patients) to conduct the highest‐level comparison between kinematic alignment (KA) and mechanical alignment (MA) in total knee arthroplasty (TKA).

Linear Mechatronic Modeling of Rectangular Tank Sloshing Dynamics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Sloshing dynamics in partially filled tanks can strongly influence system‐level behavior when fluid motion couples with rigid‐body dynamics. This paper presents a linear and acausal two‐dimensional sloshing model for rectangular tanks, based on the reformulation of established sloshing theory within a modular, multi‐domain modeling framework ...

Reachable Workspace as a Clinical Outcome for Upper Extremity Function: A Narrative Review

Muscle &Nerve, EarlyView.
ABSTRACT Motion sensing technology can be utilized to capture detailed upper extremity (UE) motion to reconstruct an individual's three‐dimensional (3D) reachable workspace (RWS). The RWS can be quantified as relative surface area (RSA), providing an innovative surrogate measure to assess UE mobility and function.

Integrating Grain to Ground Motion Data for Critical Rock Bridge and Slope Failure Analysis

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Rock masses can fail catastrophically with little warning, yet their stability depends on hidden internal connections that channel forces and localise damage. Among these, rock bridges–a “known unknown” in slope mechanics–lock fractured rock and control how failure unfolds, but their concealed geometry and uncertain strength obscure where and ...

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.
