Because of hydrodynamic force and surrounding environment disturbance,the tail of body interact with vehicle wall and generate planing force,which induces system has great nonlinearity and unstable navigation state.

To analyze the force characteristics of the vehicle,it is necessary to linearize the planing force and cavity lift.

Owing to the existence of planing forces and cavitation,modeling and control problems for supercavitating vehicles are very complicated.

The automobile resistance of taxiing coefficient determination method is introduced.

Engine Fuel Injection Control Research from Vehicle Normally Driving to Sliding Period;

In order to improve such conditions,the field investigation and testing for the causes for sliding of rolling stock are made,the sliding detection device is developed,the railway cars and lines where sliding is likely to happen are found out,the theoretical analysis is made,and.
