Mechanism Optimal Design And Kinetic Analysis Of Dynamic Seat

Dynamic seat is auxiliary and even taking place of six degrees of freedom in some flight subjects simulator;In order to improve the flight simulation fidelity of dynamic seat,this paper mainly study and analysis mechanism of dynamic seat, through the optimizing on evaluation index on of mechanism parameters to improve its dynamic performance.And also do the research and analysis on the incentives algorithm of dynamic seat.Seeking dynamic seat as the research object, analysis the performance of athletic systematic.Lagging institution was established based on principle of virtual work method of forward kinematics model and inverse kinematics model, respectively from the Angle of mechanism, kinematics and dynamics transport agency model has carried on the positive solutions and inverse solution.The kinematic equation was deduced and construct the Jacobi matrix of the equation are expounded based on the speed of the Jacobi matrix ellipsoid, acceleration ellipsoid and generalized inertia ellipsoid body kinematics performance evaluation method;Introduces the ellipsoid evaluation method commonly used in several kinds of evaluation indexes.deduce global conditions by introducing driver error coefficient.Using MATLAB software to institutions carried out simulation on the performance evaluation index, combined with the generalized inertia ellipsoid and the distribution of the acceleration simulation results to evaluate the institutional defects of kinematics performance and using the theory of space model to optimize the parameters of mechanism that improved the acceleration performance.Analyzed the principle of human body receives information, studied the human sensory information, combined with pilot’s stress in flight simulation dynamic seats,human vestibular sensory system is established and the mathematical model of body feeling pressure system.Motivate algorithm for flight simulator dynamic seat were studied and compared, in the process of the optimal filtering algorithm to establish modelintroduces the pilot’s body feeling, get the feeling model, the optimal filtering algorithm contains the human body.Flightlab flight simulation software, was used to classic filtering algorithm, adaptive filtering algorithm and optimal filtering algorithm in dynamic seats to stimulate response of simulated, and concludes that the introduction of the human body feeling model the optimal filtering algorithm can make the flight dynamic seat to get more accurate simulated results.
