Force Analysis And Computer Simulation Of The Subsoiler In Working State

Protected farming is an important item of agricultural persistent development, and take on significance and graveness. Many year's practice show that subsoiler is an important tool of agricultural protected farming, and the subsoiling technique is an technology and measure that promote the agricultural persistent development. And the field of scientific research have been attached importance to research of subsoiling and develop of subsoiler, and gained considerable development, but subsoiling technology has not been extensive application, subsoiler has so many limitations too, and great resistance is prominent limitation.This dissertiation start with improving the status of resistance, optimizing parameter of structure, ploting structure graph of subsoiler by AutoCAD, and constituting mathematical model of subsoiler resistance, finding out every affect factor of resistance, it is not only significant to optimize subsoiler, but to gain more precise value and parameter. And that it can detract the process of producing sample, experimentation and correcting, in addition to economizing time, saving resource and enhancing efficiency. At the same time, the dissertation compiling the program to solve the mathematical model by Visual Basic, predigest consequently process of solving and grain more precise value, on the side, compare resistance state of the different parameter and simulate the curve of resistance to optimize sciencly structure and design parameter of subsoiler. And then validate the mathematical model by trough experimentation, prove that the model can show totally draughting resistance of subsoiler. At last, simulating process of work by programming in Visual Basic, observe distinctly situation of working and resistance and precisely control the process of work and design better performance of subsoiler.
