| 摘 要： | 建立了深松、铺管、施肥一体铲的动力学模型,并进行了仿真分析。深松、铺管、施肥一体铲是一种具有深松、犁底层下铺渗灌管及施肥的多功能联合作业铲。依据一体铲的工作原理,建立了一体铲在工作时所受到的水平阻力模型,该阻力由深松、铺管和施肥3部分的水平阻力构成。将一体铲三维模型导入ADAMS仿真软件中进行了动态仿真,主要分析了工作深度和行走速度对水平工作阻力的影响。结果表明:一体铲的水平工作阻力与拖拉机的行走速度成抛物线函数关系;一体铲的水平工作阻力与工作深度近似于成正相关的线性函数关系。通过对一体铲的动力学建模与分析,为进一步设计、改进一体铲提供了参考依据。

| Abstract: | In this paper, a dynamic model of the integrated shovel of subsoiling, pipe laying and fertilizing was estab-lished and analysed. The integrated shovel of subsoiling, pipe laying and fertilizing was a multifunctional combined work-ing shovel ,which could deep loose,lay pipe under under the plough,and fertilize. According to the working principle of the integral shovel, the horizontal working resistance model of the integral shovel was established,which was composed of three parts that were the resistance of subsoiling, pipe laying and fertilizing application. Three dimensional model was in-troduced into the ADAMS simulation software for dynamic simulation and the influence of working depth and walking speed on the horizontal working resistance was mainly analyzed. The results show that the horizontal working resistance of the shovel was a parabolic function relationship with the walking speed of the tractor and are similar to the linear function of the positive correlation with the working depth. Through the dynamic modeling and analysis of the integrated shovel, it provided a reference for further design and improvement. |
