Aimed at the difficult technical problems of the servo system and fire control system of a type of antimissile gun in the design and qualification tests,the problems such as gun fire in danger area and slide angle beyond the limit too large were analyzed,and the technical measures were proposed to solve these problems.

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.

It establishes a full-aircraft taxiing dynamic behavior analysis model,and based on ADAMS/Aircraft software establishes the fullaircraft taxiing simulation model.
