Statistical Analysis of Human Reliability of Armored Equipment

Human errors of seven types of armored equipment, which occur during the course of field test, are statistically analyzed. The human error-to-armored equipment failure ratio is obtained. The causes of human errors are analyzed. The distribution law of human errors is acquired. The ratio of human errors and human reliability index are also calculated.     

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.

冻融疲劳作用下LHFRC损伤演变规律

为了研究层布式混杂纤维混凝土（LHFRC）在冻融疲劳作用下的损伤演变规律，提出了混凝土抗冻劣化的损伤演变数学模型，同时进行了普通混凝土（OC）与层布式混杂纤维混凝土的冻融试验，并在试验的基础上，回归出它们的冻融损伤演变方程。结果表明，LHFRC和OC的初劣点值相同，且在劣化初始阶段具体相同的损伤演变方程；在劣化扩展阶段，LHFRC和OC均具有幂函数形式的损伤演变方程，但LHFRF损伤变量小于同期的OC，钢纤维和聚丙烯纤维有效地抑制了其内部损伤发展。     

基于公共对象请求代理架构和面向对象着色Petri网的分布式系统开发

网络的发展带来了越来越多的异构性,从而给分布式系统开发带来了很大的困难。公共对象请求代理架构(common object request broker architecture,CORBA)技术有效屏蔽了异构性,使其在分布式系统开发中起着重要作用。Petri网作为一种系统的数学和图形描述与分析工具,非常适合对具有分布性质的系统进行建模。针对CORBA编程,整合面向对象和Petri网,定义了一种面向对象着色Petri网,并在此基础上介绍了基于CORBA和面向对象着色Petri网的分布式系统的开发过程,最后给出了一个简单实例。
