弹性与刚性深松部件对深松机牵引阻力的影响
Experimental Study on the Tractive Resistance of Elastic and Rigid Subsoiling Parts
摘要
Abstract
To analyze elastic and rigid subsoiling partsˊ influence to tractive resistance, with spring-tooth subsoiling shovel and rigid subsoiling shovel as research object, this experimental tested tractive resistance and vibrating of these two types of shovels. Through the stress analysis for two shovels, the following results were obtained. Compared with rigid subsoiling shovel,the tractive resistance of spring-tooth subsoiling shovel had reduced by 9.95% and specific resistance had reduced by 14.52%. Spring-tooth subsoiling shovel had better drag reduction performance. The orthogonal test analysis showed that when the choice of the elastic tooth type of deep loosening shovel, forward speed was 1m•s-1, tillage depth was 25cm, the traction resistance and power consumption were the minimum. The spring-tooth subsoiling shovel was suitable for loosening the soil of the tillage layer, and the rigidity subsoiling shovel was better for deep loosening plough bottom hard soil.The vibration frequency of spring-tooth subsoiling shovel was 5.86Hz. The vibration frequency of rigid subsoiling shovel was 4.39Hz. The main reason for the vibration of spring-tooth subsoiling shovel was the change of soil resistance.关键词
