主 题：Rubber track Static steering torque Friction model Chassis Maneuverability Vehicle
摘 要：Tire and rubber track interchangeable chassis combines the advantages of tire and rubber track,which can greatly improve the maneuverability of military construction ***,there is almost no effective calculation model for the real-time static steering *** the relative sliding speed is greater than 0.01 m/s,the influence of friction heating can not be *** improved LuGre model is established to calculate the static real-time steering torque of tire and rubber track interchangeable ***,the friction heating model between rubber and ground is *** with the influence of temperature on the dynamic performance of rubber material,the influence of friction heating on the stiffness and friction coefficient of rubber track is analyzed,and the improved LuGre friction model is *** steering torque of tire and rubber track interchangeable chassis is affected by rubber material properties,steering speed,pavement type,and ambient *** with the original Lu Gre model,the improved LuGre model captures the change in friction torque during multiple in-situ turns due to frictional *** error with the experimental data is small,which verifies the effectiveness of the improved LuGre model.
