摘要
为减小液态施肥机的振动,实现平稳施肥作业,采用结构简单、运转平稳的椭圆齿轮机构作为液态施肥机的执行装置。本文在分析椭圆齿轮传动原理基础上,建立模糊可靠性优化模型。利用MATLAB软件编程,获得椭圆齿轮各优化参数。通过与期望值相比较,优化设计精度达到99.98%,可靠度提高2.551%。运用ADAMS进行仿真,得出从动轮角速度与主动轮极角之间的关系曲线以及传动比仿真值,与理想值相比较,误差精度符合实际工作要求,证明优化结果真实可信。此优化方法及仿真试验提高了椭圆齿轮设计的效率、精度和科学性,为机器的进一步研究提供理论依据。
In order to minimize the vibration of liquid fertilizer applicator, and achieve a steady fertilization operation, an elliptic gear mechanism was used as actuating mechanism in liquid fertilizer applicator. The elliptic gear has a simple structure and steady movement. On the basis of analyzing transmission principles of elliptic gear, a fuzzy reliability optimization model was established. Each optimization parameter of elliptic gear was obtained using MATLAB procedure. Compared with expected values, the precision of optimization design was increased to 99.98%, the reliability was improved by 2.551%. With the simulation using ADAMS, the relational curve between driven wheel angular speed and the driver polar angle was obtained, and also the simulated value of transmission ratio was obtained. In comparison with the ideal values, the error satisfies the practical requirement. It proves that the optimization results are credible. The optimization method and simulation study improve the efficiency, precision and scientific backing of elliptic gear design. This study provides a theoretical reference for further study.
