弹体动不平衡度的静态测试法

基于支持向量机（SVM）在处理小样本、高维数及泛化性能强等方面的优势，提出了基于主元分析和支持向量机（PCA—SVM）对过程进行监控的方法。文中先利用主元分析方法进行特征数据提取，得到降维的主元特征向量，去除了高维样本变量相关性。然后分析各状态T^2统计、SPE统计量的变化趋势，对实际生产状况进行监控，最后利用SVM与最近邻法相结合的策略对特征向量进行分类识别。试验结果证实了提出算法的有效性。     

Submarine Magnetic Field Extrapolation Based on Boundary Element Method

In order to master the magnetic field distribution of submarines in the air completely and exactly and study the magnetic stealthy performance of submarine, a mathematic model of submarine magnetic field extrapolation is built based on the boundary element method （BEM）. An experiment is designed to measure three components of magnetic field on the envelope surface surrounding a model submarine. The data in different heights above the model submarine are obtained by use of tri-axial magnetometers. The results show that this extrapolation model has good stabilities and high accuracies compared the measured data with the extrapolated data. Moreover, the model can reflect the submarine magnetic field distribution in the air exactly, and is valuable in practical engineering.     

Static Stiffness Analysis of a New Type 6-DOF Micro-manipulation Robot

A 6-DOF micro-manipulation robot based on a 3-PPTTRS mechanism is proposed in this paper. Its static stiffness is an important index to evaluate load capacity and positioning accuracy. However, it is insufficient to consider the static stiffness only when the robot is in its initial pose. The stiffness in different positions and poses in its work space must be analyzed also. Thus a method to analyze the relationship between static stiffness and poses in the whole work space is presented. A static stiffness model is proposed first, and the relationship between structural parameters and static stiffness in different poses is discussed. The static stiffness analysis provides foundation for structural parameter design.     

Dynamic Study on Rigid and Flexible Coupling System for Terminally Sensitive Submunition

A kinetic model of the rigid and flexible coupling system for terminally sensitive submunition is set up with Kane＇s method. The parachute is considered as a flexible body, the flexible displacement is expressed with modal spread method, the position of the parachute is expressed with a hybrid coordinate method, and the kinematics of the terminally sensitive submunition is analyzed. Ten generalized coordinates relative to the attitude of the terminally sensitive submunition are chosen, and the correlative generalized active forces, the generalized inertial forces, the generalized internal forces are calculated in turn. On the base of the Kane＇s method, the ten degrees of freedom dynamic equations for the coupled terminally sensitive submunition are finally set up. This model can be used to expediently simulate and analyze accurately the exterior ballistic trajectory of terminally sensitive submunition, and provide the overall design of the terminally sensitive submunition with some helpful references.     

Study on Storage Reliability Evaluation for Ammunition Using Gibbs Sampler

For the gradual maturity of Bayesian survival analysis theory, as well as the defects of the traditional methods for storage reliability evaluation, the Bayesian survival analysis method is proposed to build regression models for reliability in the random truncated test. These models can reflect the influences of different environments on the ammunition storage lifetime. As an example, the common exponential distribution is used here, and Markov chain Monte Carlo（MCMC） method based on Gibbs sampling dynamically simulates the Markov chain of the parameters＇ posterior distribution. Also, the parameters＇ Bayesian estimations are calculated in the random truncated condition. The simulation results show that the proposed method is effective and directly perceived.
