以水稻插秧机分插机构为研究对象,进行了运动学和动力学分析,建立了计算机模型,其中包括自动绘制特性曲线子程序。该模型与以往国内外研究的不同之处在于,它模拟了推秧装置在工作过程中对机构的动力学作用。研制了试验台,对2ZT-935型插秧机分插机构曲柄轴受力进行了测试。理论计算和测试结果比较表明:它们基本是吻合的,也验证了推秧装置是机构的主要振动源,在理论分析中是不能忽略的。利用模型建立起来的程序,对该机构生产上可行的改进方案进行了优化计算,并且再次进行试验验证,得到了最佳改进方案。该模型和试验台适用于各种机型的分插机构的理论分析和试验。
Taking rice transplanter as a research object, kinematics and dynamics analysis were carried out, and a computer model was established, which included automatic drawing of characteristic curve subroutine. The difference between this model and the previous studies at home and abroad is that it simulates the dynamics of the mechanism during the operation of the device. The test bench was developed to test the stress on the crank shaft of 2ZT-935 transplanter. The comparison between the theoretical calculation and the test results shows that they are basically consistent, and also verified that the poplar planting device is the main vibration source of the mechanism, which can not be neglected in the theoretical analysis. The program established by the model is used to optimize and calculate the feasible improvement scheme of this institution, and the experiment is validated again to get the best improvement plan. The model and test bench for a variety of models of substituting institutions theory analysis and testing.
