钢索传动涉及的主要另、部件有钢丝绳、滑轮组、卷筒和吊钩。吊钩可按起重量大小,直接从国家标准中查取;其余另、部件则主要靠经验公式并结合标准规范加以选择。不过由于所定滑轮组的倍率不同,可能会出现多种传动方案,应当从什么角度衡量方案的优劣并加以优选呢?本文试图就钢索传动的主要另、部件(钢丝绳、滑轮组和卷筒)具有最小重量(亦反映其成本最低)为目标,以卷筒收、放钢丝绳时的最大偏斜角等作为限制条件,提出一种利用简便程序对离散变量进行优选的设计方法供大家参考。
The other major components involved in cable transmission are wire ropes, pulley blocks, reels and hooks. Hooks can be from the weight of the size, directly from the national standard check; the other, the components are mainly based on empirical formulas and standards to be selected. However, due to the different ratios of the given pulley block, a variety of transmission schemes may appear and at what point should the pros and cons of the scheme be measured and be optimized? The main purpose of this paper is to provide the main components and components (wire ropes, pulley blocks and reels) Minimum weight (also reflects the lowest cost) as the goal, take the reel, put the maximum skew angle when the wire rope as a constraint, the use of a simple procedure for the discrete variable optimization design method for your reference.
