When the suspended depth charge is used to explore the torpedo, how to estimate the range of course angle correctly becomes the key point to lay the suspended depth charge accurately, if the distance to the aim can only be estimated by the experience of sonar soldiers.

Evasive maneuver is one of key problems a surface ship faces while releasing suspended depth charge to intercept a torpedo.

Based on the structure and working principle of anti-torpedo system of suspended depth charge,operational effectiveness model of anti-torpedo system of suspended depth charge is proposed.

Based on this,center position of the suspension interception missile is ascertained.

This paper gives ballistic equation for the suspended projectile under nonstandard conditions,gives parameter correction method for nonstandard trajectory,weather and terrain,establishes a math model for simple and quick solution of firing data,and the paper conducts simulated computation.

To study the dynamic uncoupling capacity of the elastic suspension chassis when the multi-controllers were simultaneity running, the model of the high speed EMS maglev system was established which has several cascade PID controllers and the dynamic response of this model was analyzed.

In order to reduce the probability of bonding and lengthwise direction fold in process of hood-type annealing, choosing hood-type annealing production line of BaoSteel 1220 plant as subject investigated, this thesis puts forward a new suspension type coil stacking version and it has high theoretical sense and use value.
