In this Paper, the theory of optimization modeling and computer application for Planning the development of a hydropower reservoir system in cascades, are introduced. It is a comparatively new method of hydropower Planning which will lessen considerable amount of Planning work. After careful analysis by considering the effective storages of the reservoirs as state variables, the regulated discharges from the reservoirs as decision variables and taking the Procedure of solving the recursions along the downstream direction, a simple and efficient approach by dynamic Programming model has been Proposed. The reservoir system of Hongshui River cascades is used as a case study, in which the computation has been done by ALGOL language

将最优化、模型化和电算化的理论和方法引进到现有水能规划设计中来,这是一个崭新的研究课题,也是加快水能规划设计工作的唯一正确途径。本文在这一方面作了初步探讨,将动态规划具体应用到梯级水电站水库死水位的选择中来。文中着重论述动态规划模型的建立,对状态变量、决策变量和方程递推求解方向的选定作了较深入的分析之后,提出了以有效库容作状态变量、以调节流量作决策变量和按水流方向逐级顺序递推的最简捷的解题方法。并以红水河梯级开发为实例,用ALGOL语言编制程序,在TQ-16机上进行计算,以常规方法所得成果加以对比,证实了所建议的方法是完全可行的,成果是可信的。

This paper puts forward a mathematical model for the optimum design of the connecting rod with horizontal split big-end for internal combustion engines as well as its computer program. In adopting this model, the lightest connecting rod can be designed automatically within the specified limits of strength and rigidity on a computer.In this model the author uses the finite element method to analyse the structure of the connecting rod with the weight of the connecting rod as the target function and the limits of stress and deformation of connecting rod as the restricted conditions. The program is solved by means of the penalty function.This paper gives also an example to design the optimum connecting rod for a high speed diesel engine.

本文提出一个干切口式连杆结构最优化设计的数学模型及其计算程序。采用这个最优化模型,可以获取满足强度、刚度等各种设计要求而又最轻的一个最佳连杆结构方案,从而可以在电子计算机上实现连杆结构的自动化设计。在本文所叙述的连杆最优化设计方法中,对于连杆的结构分析采用了有限无法数值计算技术。最优化设计的目标函数选为连杆的重量,将连杆应力、变形和疲劳安全系数的设计限制作为约束条件,求解这一非线性规划问题采用了罚函数法。文中还以一台高速柴油机连杆结构的最优化设计为例,介绍这种方法的应用。
