引言 在主轴或传动轴设计中,经常涉及变截面梁的强度和刚度计算。在设计多支承轴时,会遇到解变截面超静定梁问题。虽然材料力学为这些问题在理论上提供了各种解法,实际计算过程相当复杂。笔者以梁的基本理论为基础,按数字式电子计算机的特点,选择适当的计算模型,用 BASIC语言设 INTRODUCTION In the design of spindles or drive shafts, the calculation of the strength and stiffness of variable section beams is often involved. In the design of multi-bearing shaft, you will encounter the problem of variable cross-section statically indeterminate beam. Although mechanics of materials provides theoretically various solutions to these problems, the actual computational process is quite complex. The author based on the basic theory of beam, according to the characteristics of digital electronic computer, select the appropriate calculation model, with BASIC language
