【Abstract】 How stripper headers work on crop and how the crop changes its moving state are described by analyzing the stripping process of the stripper header of stripping harvesters, and a mathematical model of moving state of the crop is derived at the same time. Using this model the moving state of the crop in the working process of stripping header can be simulated on computer, and the research on stripping theory of stripper header can be advanced. An ultimate thought analyzing several kinds of loss is presented based on the analysis of stripping process. It provides partial theoretical grounds for the computer dynamic simulation research of stripping combine harvesters. It can be also consulted when designing the structure of a stripper header.更多还原
