根据耕作与驱动领域的特殊要求,研制了适用于测量常用耕作速度范围内土壤抗剪强度和金属-土壤摩擦阻力的直接剪力仪。该系统采用液压加载,利用微机进行数据采集和处理,具有较高的测量精度和自动化程度。该系统的研制为农业工程领域中土壤力学参数的研究提供了必要的手段。
According to the special requirements in the field of tillage and drive, a direct shear instrument suitable for measuring soil shear strength and metal-soil friction resistance in the commonly used tillage speed range was developed. The system is hydraulically loaded and uses microcomputers for data acquisition and processing, with high measurement accuracy and automation. The development of this system provides the necessary means for the study of soil mechanics parameters in the field of agricultural engineering.
