履带式拖拉机作业性能的计算机模型

本文建立了农用履带式拖拉机田间作业的微机模拟模型。该模型将发动机特性、传动系、行走系特性及土壤强度性质容为一体,以模拟整体拖拉机田间作业。文中列出了具有代表性的模拟结果,与实验数据进行比较表明,模拟结果能够较为准确地反应实际情况。该模型可用来模拟田间试验、研究土壤强度和拖拉机参数对拖拉机作业性能的影响,对拖拉机使用性能的研究将起到一定的作用。

COMPUTER SIMULATION OF DRAWBAR PERFORMANCE FOR A TRACKED TRACTOR IN THE FIELD

A computer simulation model was developed to predict drawbar performance for a tracked tractor in the field. The model considered engine characteristics, transmission, track characteristics, and soil strength properties, which combine to represent a physical tractor in the field, Typical outputs of the model was presented. Predicted and measured performances were compared and they were in reasonably goad agreement. The model can be used to analyze the effects of tractor and soil strength parameters on tractor performance, It is a useful tool for optimizing tractor performance in the field.
