Computer Stochastic Processing of Fuze Overload

The method which can simulate the stochastic process of the overload during the course of a projectile launching is discussed in detail.The calculated theory bases on the principle of information diffusion in fuzzy theory.To approach the actual launching overload,the calculated theoretical overload is disposed by the white noise.The dynamic test is used to calculate the fuze response of the launching overload.Finally,the launching overload of a projectile fuze is simulated to verify the validity of the method.The result is found basically to be in accord with the actual launching overload of the fuze,and the calculation accuracy is perfect.

试论联合办学管理体制

联合办学是在十一届三中全会以后出现的一种新的办学形式。它的出现,给教育事业的发展和教育管理体制的改革带来了生机和活力。近年来,我校与能源部、轻工业部、纺织工业部、四川建设部等单位实行联合办学,共建立了四个联办的学院,利用办学经费征地400余亩,使学校的占地面积由原来的500余亩扩大到918亩,形成一个联合办学新区,现各学院将陆续建成。     

（五）窗式空调器的减振降噪技术

空调器是人们生活、工作、科研环境等必需和深受人们欢迎的用品,因此研究发展很快,目前已有系列产品,如:窗式,分离式,璧挂式,柜式,中央空调等。我们已搞了几种空调器的噪声控制,一般均能减小振动降低噪声,使原有产品提高了档次又延长使用寿命。窗式空调器对室内环境的噪声影响是不容忽视的,减振、降噪的难度又较大,这就需要进行系统分析,充分利用现有的理论和新技术致力于对不同类别、牌号的空调器实施减振、降噪。我们的研究已取得成效,具体思路如下:

The calculated theory bases on the principle of information diffusion in fuzzy theory. To approach the actual launching overload, the calculated theoretical overload is disposed by the white noise. The dynamic test is used to calculate the fuze response of the launching overload. Finally, the launching overload of a projectile fuze is simulated to verify the validity of the method. The result is found basically to be in accord with the actual launching overload of the fuze, and the calculation accuracy is perfect.     

m条对角线的n阶对角矩阵压缩存储的通用寻址公式

本文将通常数据结构中三对角矩阵压缩存储的寻址公式推广到ｍ对角矩阵（具有ｍ条对角线的ｎ（〉ｍ）阶矩阵）的情况，得到了新的一般寻址公式。同时指出文献「２」中关于这个问题所给出的公式是错误的。并用具体例子加以说明。     

Mechanism Modeling and Simulation Based on Dimensional Deviation

To analyze the effects on motion characteristics of mechanisms of dimensional variations, a study on random dimensional deviation generation techniques for 3D models on the basis of the present mechanical modeling software was carried out, which utilized the redeveloped interfaces provided by the modeling software to develop a random dimensional deviation generation system with certain probability distribution characteristics. This system has been used to perform modeling and simulation of the specific mechanical time delayed mechanism under multiple deviation varieties, simulation results indicate the dynamic characteristics of the mechanism are influenced significantly by the dimensional deviation in the tolerance distribution range, which should be emphasized in the design.     

发动机缸体压铸工艺数值模拟及合金成分优化

根据发动机缸体的结构特点,在铸造ADC12铝合金成分的基础上,调节铝合金中Fe、Cu、Mn的含量,通过提高Fe含量,降低Cu含量来降低合金的成本,最后通过ProCAST软件对发动机缸体的充型凝固过程进行数值模拟。结果表明,根据铸件的温度场、充型流动情况、凝固场、固相率、铸件缩松、缩孔所在位置及孔隙率,模拟结果优化了铸件的压铸工艺参数。在浇注温度为680℃、模具初始温度为240℃、压射速度为12 m/s的条件下,调节成分后的发动机缸体模拟方案更优。
