【摘要】 作者根据手扶拖拉机优化调整跟踪试验的数据,分析了手扶拖拉机性能参数和技术参数随时间变化的规律。应用灰色系统理论中关联度分析方法,找出了造成手扶拖拉机在实际使用过程中机况恶化的主要技术参数,并制定了主要技术参数检测调整的适宜期限。更多还原

【Abstract】 According to the results of following survey of walking tractors in use, the rule of the change with time of the tractor’s property parameters and technical parameters were analyzed. By applying the relational grade to the grey system theory, the main technical parameters influencing walking tractor’s proterty parameters were found out. Suitable adjustment time of the main technical parameters were worked out.更多还原
