Based on the theory of grey target,the patterns of different schemes on the overland mobility of tank are formed with the principal tactical and technical performance indices,and then a standard pattern is constructed according to ideal or better performance values.

Track searching of simulating platform of tank engine s movement state based on improved genetic algorithm;

The platform is a test-equipment which is used to simulate the tank engine s movement state.

On the basis of extracting the characteristic parameters form tank engine vibration signals,and by combination of C gray cognate analysis which is easy to fulfill and the BP neural network diagnostic method which is accurate, the fault pattern recognition and diagnosis are fulfilled for the tank engine.

Aiming at the existing problems of poor sealing effect and service and maintenance of an amphibious tank′s turret ring,this paper adopts a particular technique scheme which takes the solution combining active sealing and passive fast clearout and conducts specific design and true-vehicle tank experiment for this solution,which validates the feasibility and validity of this scheme.

The amphibious tank s double power switched device has the defect,when it is manipulated,which is felt inconvenience.

This paper is with an eye to man-machine-environment system optimization of 63A amphibious tank sea firing.
