Combined with a linear two degrees of freedom vehicle model, a kind of new integrated feedback control strategy, which is on the basis of weighting factors of the realtime yaw rate and the lateral acceleration, is put forwards in this paper. An ideal variable steering ratio strategy is developed and the corresponding controller is also designed. By the computer-simulation technique, the double ...

OBJECTIVE To examine regional wall acceleration and its relation to relaxation. STUDY DESIGN 8 sheep were examined by tissue Doppler ultrasound imaging (VingMed Vivid FiVe) in apical four chamber views to evaluate the left ventricular wall divided into six segments and the mitral annulus in two segments. Peak myocardial acceleration during isovolumic periods (pIVA) derived from tissue Doppler...

The inertial measurement unit is popularly used as a wearable and flexible tool for human motion tracking. Sensor-to-body alignment, or anatomical calibration (AC), is fundamental to improve accuracy and reliability. Current AC methods either require extra movements or are limited to specific joints. In this research, the authors propose a novel method to achieve AC from standard motion tests (...

The design and performance evaluation of an entry guidance algorithm for future space transportation vehicles is presented. The guidance concept is to plan and track aerodynamic acceleration. This concept, on which the longitudinal entry guidance for the Space Shuttle Orbiter is based, is extended to integrated longitudinal and lateral guidance. With integrated longitudinal and lateral guidance...

This study presents the development and analysis of a technique for planning autonomous vehicle (AV) motion references using sequential optimization. The method determines trajectory plan, speed acceleration distributions, other AV kinematic parameters. approach combines basics finite element (FEM) nonlinear optimization with constraints. First, we briefly described generalization representing ...

The proposed method allows evaluating an automobile handling with or without accounting withdrawal, various types of drive wheels and steering using partial acceleration. Determination lateral tangential reactions on tire while turning in view slip more accurate maneuverability, stability handling. vehicle total angular accelerations during its driving into rotation withdrawal developing vehicl...

Turnouts are the weak spot in high-speed rail systems, and it is simple for phenomenon of wheel–rail force carbody lateral acceleration over-limit to arise when train passes through, which affects service life running stability train. In this paper, turnout with selected analysis, profiles wheel monitored. Then, vehicle–turnout coupled multi-body dynamics model simulated. Additionally, portable...

semi-active base isolation system has been proposed mainly to mitigate the base drift of isolated structures while in most cases, its application causes the maximum acceleration of superstructure to be increased. in this paper, designing optimal semi-active base isolation system composed of linear base isolation system with low damping and magneto-rheological (mr) damper has been studied for co...
