Aiming at computing the force feel to be simulated at real time, thrust lever control loading system’s simulation model is set by software called SimMechanics after its control mechanism being analyzed. The dynamic characteristics of control systems and model torque are studied based on the simulation model. Then the counter potential, primary element to cause the surplus torque, is pointed out according...
When flying an aircraft, the force feel of the control column provides the pilot with important information about the state of the aircraft. In a flight simulator this force feel needs to be simulated, which is the task of the control loading system. A hydraulic Control Loading System (CLS) was developed and installed on our flight simulator earlier days, but the CLS contains instabilities for some...
Using the traditional mathematical modeling methods to build dynamics model of motion system of flight simulator - - hydraulically driven Stewart platform, there existed defects such as modeling process is relatively complex, simulation can't provide visual information and so on. To solve the problems, it adopted co-modeling method by combining ADAMS and Matlab/Simulink together, using ADAMS built...
Large terrain is an important component of the virtual visual environment in the flight simulator. This paper presents a view-dependent dynamic LOD algorithm which is inspired by the geometry clipmap, and has some supplement or improvement in data structure, refinement criterion, rendering way, etc. The algorithm treats the terrain data as vertex texture; carries out uniform management on the terrain...
