| 中文摘要: |
| 目的 获得机电混合驱动弧面凸轮机构的运动规律。方法 针对解析法无法直接求解非线性运动叠加的问题，采用数值分析的方法对其运动规律进行分析研究。将分析后得到的数值点代入到已编写好的Matlab程序中，并进行运算求解。对3种不同非线性运动规律与凸轮运动规律叠加后的结果进行分析。结果 经拟合得出的机电混驱弧面凸轮机构的运动规律曲线，与理论的凸轮运动规律曲线趋势相似。结论 这种数值分析的方法可有效解决非线性运动规律叠加后复合难度大、复合函数难求解的问题，在保持原有凸轮运动规律的情况下，进一步将从动件运动规律由单一化向多元化发展，且为其后续的复合运动规律的优化提供了依据。 |

| The paper aims to obtain the motion law of the electromechanical hybrid drive globoidal cam mechanism. For the problem that the analytical method cannot directly solve the nonlinear motion superposition, the numerical analysis was used to analyze the motion law. The numerical points after the analysis were put into the program, which was prepared in MATLAB to make an operation. The results of three different nonlinear motion rules superimposed with cam motion rules were analyzed. The trend of the curve of motion law of the electromechanical hybrid drive globoidal cam mechanism was similar to the curves of theoretical cam motion law. This method of numerical analysis can effectively solve the problem of great difficulty of compositing and the compound function. Under the condition of maintaining the original cam motion law, it promotes further development of motion law from singularization to diversification and lays a foundation for the optimization of its subsequent composite motion law. |
