| 1. | Through newton ’ s law of motion , the continuous model of the cantilever is built . the author discretizes the model through lumped mass method and supposed modal method , analyzes the discretized model through influence coefficients method . compare the results of the two models ; the general analysis method of non - uniform beams is obtained 其次,对悬臂梁结构进行了理论分析,应用牛顿运动定律,建立了悬臂梁系统的连续模型,并用集中质量法和假设模态法对悬臂梁系统进行了离散化,运用影响系数法对离散化后的系统进行了分析,并把分析结果和连续系统进行了对比,得到了变截面梁的一般分析方法。 |
