Analysis And Research On Driving Behavior Of Carrier-based Aircraft Tractor

With the rapid economic development of various countries and the increasing scarcity of land resources,the protection of marine territorial resources has become a national mission.The carrier-based aircraft formation is a symbol of a country’s military capability and comprehensive strength,and is also an important military force to safeguard maritime territorial rights.As the main towing tool for carrier-based aircraft,carrier-based aircraft tractor plays an irreplaceable role.Due to the limited space above the aircraft carrier and the influence of the complex environment of the ocean,the research on the driving behavior of the aircraft carrier tractor is of great significance to improve the efficiency of the carrier aircraft and improve the safety of the traction system.This paper mainly studies and analyzes the stability characteristics of linear traction motion and the stability of steering traction in the driving behavior of carrier-borne tractors,and then provides theoretical support and reference for improving the efficiency and safety of carrier aircraft scheduling.Through consulting the related research on the running performance of carrier-based aircraft tractor at home and abroad,the research scheme for this topic is formulated.Through the analysis and study of the marine environment,the motion state of the carrier is determined,the kinematics model and dynamics model of the carrier-based aircraft tractor system are established.On the basis of the established traction system model,considering the influence of sea state level,crosswind level,traction speed and traction tonnage and other conditions,the driving characteristics of the carrier-based aircraft traction system in straight and steering driving are simulated,and the response curves of the carrier-based aircraft and tractor in different driving conditions are obtained and analyzed.Based on the analysis of the running characteristics,the lateral stability control system of the traction system is established.The fuzzy PID controller and the optimal slip ratio logic threshold controller work together to reduce the yaw rate of the carrier-based aircraft and the tractor by reducing the additional yaw moment in the movement of the traction system,so as to improve the running stabilityof the traction system.
