优化设计就是将实际的技术问题抽象成为最优化的数学模型,选择一种合适的优化设计方法,使用电子计算机来求导数学模型,得到最佳方案的先进产品设计方法。 本文以向心球轴承为例,对设计过程中目标函数的建立、设计变量与约束条件的确定等加以论述。经过优化设计的向心球轴承,其额定动负荷(C值)有一定的提高。附图3幅,表1个。 Optimal design is the abstraction of the actual technical problems into the optimal mathematical model, select a suitable optimization design method, the use of electronic computers to derive mathematical models, the best solution for advanced product design methods. In this paper, the radial ball bearing is taken as an example to discuss the establishment of objective function in design process, the determination of design variables and constraints and so on. The optimized design of the radial ball bearings, the rated dynamic load (C value) has a certain increase. Figure 3 Figure, Table 1.
