Abstract: In order to solve the problem of mismatch exist between angular motions by Sustained-G Flight Simulator pilot through his proprioceptive receptors and visual receptors, the control algorithm of Sustained-G Flight Simulator is designed. The formulas relative to control input is derived; the mathematical model of human proprioceptive system is researched, the relationship between pilot's perceptual angular and rotating linear acceleration vectors and angular accelerations is given, based on that, the control algorithm of Sustained-G Flight Simulator is proposed, which can make a match existence between the angular motion perceived by Sustained-G Flight Simulator pilot and aircraft pilot. The simulation …

Trajectory Planning Method Of Overhead Crane, Xuejuan Shao, Li Yao, Jinggang Zhang, Xueliang Zhang
Journal of System Simulation
Abstract: To make the trolley of bridge crane move stably with smooth acceleration, a polynomial acceleration trajectory is proposed based on the constraint conditions of the crane and the friction between the trolley and the rail. An anti-swing plan is designed employing the dynamic coupling relationship between the motion of the trolley and the load swing. Results indicate that when the length of the rope is changed, the swing angle of the trolley is still within the limits. The stability of the system is proved by constructing Lyapunov energy equations, and the Barbalat lemma confirms that the planned reference trajectory …

Differential Games Of The Second Order, B. T. Samatov Doctor Of Physics-Mathematics, Professor, U. B. Soyibboev Master Student, U. A. Mirzamahmudov Master Student
Scientific journal of the Fergana State University
In this paper, we study the pursuit-evasion problem for the second order differential game when the initial positions of moving objects are linearly dependent and controls of the players have geometric constraints. The new sufficient solvability conditions are obtained for problems of the pursuit and evasion.

Manufacturing And Testing The Permanent Magnet Linear Motor, Renjie Kang
Senior Theses
Controlled mechanical motion is vital in many useful applications in technology. Among them, linear motors have advantages over traditional rotating motors. In this work, we built a permanent magnet linear motor to test and measure its energy efficiency. A maximum 29% total energy efficiency, and 67% energy transfer rate, were detected. In addition, a C-shape support structure was added to the moving part in order to increase the moving accuracy. The tests show that, with the support structure, the fluctuation in the vertical direction decreases significantly, but the friction of the system slightly increases.
Effects Of Change In Tire Pressure Upon Efficiency Of A Vehicle, Haider Ali Khan
Effects Of Change In Tire Pressure Upon Efficiency Of A Vehicle, Haider Ali Khan
Undergraduate Journal of Mathematical Modeling: One + Two
The objective of this paper is to compare the difference in the efficiency of acceleration, of a 2018 Audi A8, in two distinct scenarios where the tire pressure is kept at a maximum and partial level. The approach towards solving the issue is multi-faceted, the efficiency is dependent on the difference in the time it takes for the car to accelerate, thus to obtain the elapsed time, the foundational basis is set by the relations between Torque/Force, and RPM/Speed of the vehicle. All the calculations are completed by using the data extracted from the car’s specifications set (Automobile Catalog). Newton’s …
