分析了船上泵源液压系统压力脉动产生的原因及频率成分。根据气体消声器的原理,结合液压系统高压、大流量等工作特点,设计和制造了一种基于流体-结构(fluid-structure)耦合振动的结构共振式液压脉动滤波器,并推导出其波动衰减的传递矩阵模型。通过调整液压泵转速来改变压力脉动频率,在液压系统压力脉动试验平台上进行了三组对比试验。试验表明,当滤波器的结构振动体固有共振频率与系统频率接近时,系统的脉动能量得到有效衰减,系统的压力波动幅度和脉动率大幅降低。试验结果验证了结构共振式液压脉动滤波器的使用效能和存在的不足,它为液压系统振动控制提供了新的技术手段。

This paper proposes a distributed control law for three mobile autonomous agents to shape an acyclic triangle *** move themselves autonomously in two orthogonal axes to pursue and maintain the prescribed distances to their *** dynamical system approaches exactly to the desired edge lengths and the orientation of the triangle in any initial condition except initial collocation of agent 1 and *** minimally rigid graphs with more than three agents constructed by the Henneberg sequence,using orthogonal control law leads to the exact formation *** analysis of the dynamical system shows the exponential convergence to the only stable equilibrium which corresponds to the desired formation.A set of three variables is defined to describe floating triangle formation,which neglects the translation and rotation of triangles but not its flipping over in the *** variables are also used as a set of state variables of the floating triangular formation to show the trajectories of the dynamical system.

Focussing on unification of concrete portions into a generic form of computational evolution,a generalized theoretical framework is necessary and imperative to be built to construct a universal computational theory of evolution *** NP problem solving capacity can be traced to the nature of metaevolution mechanism with emergence features that determine corresponding homeostasis and diversity ranging in the domain of nonlinnear mapping from genotype to *** this paper a criterion that guarantees the global optimality of evolutionary computation process is proposed and proven *** global optimization criterion obtained is based on the nonparametric measarement for the whole evolution system and has great flexibility and *** leaves room for evolutionary system designing and *** formulization of the global description in statistical manifold space of information object family expresses evoluable evolutionary operator architecture and operation procedure in terms of evolution by *** theoretical results are helpful to applications such as machine learning for automatic knowledge acquisition,pattern classification and recognition of complex images(***) and unsupervised system identification of nonlinear dynamical systems as well as chaos *** kernal of the formal system guided by global evolutionary optimization is proper to the implementation with objectoriented programming paradigm and abstract machine modelling.
