This paper discusses Lagrange s equations of motion of a holonomic system for impulsive forces, introduces the action of virtual work and discusses the calculation of generalized impulse, finally, discusses the solving process of analytical mechanics for impulive motion of the holonomic system.

With the foundation of the computational theory of generalized capability of urban road network,through computing the road network capability of planning year, then making certain the restricted possession of vehicles of planning year from the balanceable angle of supply and demand,which offers the important decision_making basis for the development programming of urban vehicles.

On the basis of making full use of expert knowledge, three methods for structural behavior evaluation are proposed in this paper, which are weighted average method?fuzzy comprehensive evaluation method and generalized quantification method.

This article is based on the result of the predecessors research trial,organically combined fuzzy mathematics theory with analysis principle of generalized quantification.

The process of fuzziness, fuzzy inference and defuzziness can be expressed in the sum of hyperbolic functions of generalization state variables.

It is interpreted by the research that generalized mass can be depicted as M=HΦMΦ *H *, and secondly it can be depicted as M=(I+HΦK)D(I+HΦK) *.

The inverse dynamics of the rigid multibody system is studied based on the spatial operator algebra theory,and the generalized mass procedure is realized in the environment of Mathematica 5.

To improve the generalized mass modeling efficiency of multi-body system dynamics,the recursive design and realization of the generalized mass procedure was built in the environment of software Matahematica6.
