This paper presents the multibody dynamics modeling and simulation results of bearing loads in a transmission system used in a wind turbine. First, a theoretical study is briefly reviewed that allows developing an analytical model for the analysis. The model is then studied using MD ADAMS software dedicated to the study of multibody dynamics and motion analysis of moving parts. The aim of the s...

The purpose of this study was to examine the power-strength curve in a half squat exercise in trained basketball players of the EBA league. For that, a cross sectional, descriptive study was carried out to 8 high-level male basketball players. After controlling the participants 1RM, a progressive test, consisted on moving loads of 30, 45, 60, 70 and 80% of 1RM as fast as possible in the concent...

Masticatory muscles are anatomically and functionally complex in all mammals, but relative sizes, orientation of action lines, and fascial subdivisions vary greatly among different species in association with their particular patterns of occlusion and jaw movement. The most common contraction pattern for moving the jaw laterally involves a force couple of protrusor muscles on one side and retru...

The time domain solution of the equations of motion of structures subjected to a stochastic wind field is often obtained by a step-by-step integration approach. The loading is described by simulated time histories of the aerodynamic force. Recently, autoregressive and moving average (ARMA) recursive models have been utilized to simulate the time series of wind loads. Based on the system dynamic...

We constructed a next-generation optical trapping instrument to study the motility of single motor proteins, such as kinesin moving along a microtubule. The instrument can be operated as a two-dimensional force clamp, applying loads of fixed magnitude and direction to motor-coated microscopic beads moving in vitro. Flexibility and automation in experimental design are achieved by computer contr...

As high-speed trains operate in more and more countries and their maximum speed increases, the vibration induced by the train has become an important issue. The dynamic coupling between the vehicle, track and ground has to be assessed for its effects on safety, stability and maintenance costs. A particular issue, especially for soft soils, is the critical speed at which the train reaches the wa...

This research work has addressed demand side flexibility in a smart grid oriented building. The principal purpose has been to build a short term forecasting model that will predict the next hour consumption. Three advanced methods of forecasting have been investigated for this purpose, the ARIMA (Autoregressive Integrated Moving Average) model, Artificial Neural Networks (ANN) and Support Vecto...

Motion-analysis and FEA can work together even though they are quite different. Motion-analysis software works with CAD assemblies. It starts by translating assembly mating conditions into corresponding kinematics pairs. It then calculates kinematics and dynamics data of the moving mechanism. Each component in mechanism, if viewed separately, is under balanced set of loads: joint reactions and ...
