摘　　要：为了研究气吸式免耕播种机在田间耕作时,由于免耕地表的不平度激励所产生的振动对播种机的排种装置的影响,推导了气吸式免耕播种机排种装置振动特性数学模型。同时,由所建立的数学模型得出气吸式免耕播种机排种装置的振动特性主要由播种机的结构特性、作业时的前进速度、排种器与土壤表面间的距离、土壤不平度和土壤粘性决定。通过建立振动特性数学模型,可对工作状态下免耕播种机排种质量进行预测和分析。In order to study air-suction when tillage planter in the field farming, Vibration due to the surface roughness of the resulting excitation tillage effects on seed planter of the device, Derivation of the air-suction device tillage planter seeder vibration characteristics of the mathematical model, Vibration characteristics of the mathematical model derived gas suction device tillage seeder seed planter primarily by structural properties, Forward speed when operating, Seed row distance between the soil surface, Soil roughness and soil sticky decision. Can predict and analyze working condition tillage planter seed quality through the establishment of the vibration characteristics of the mathematical model.
