GPS技术及其在农业装备中的应用研究
|
摘要
本文阐述了GPS的特点、应用现状及其在农业装备可靠性应用方面的优势。在可靠性研究中,实际载荷谱、S-N曲线及线性累积损伤理论等是计算结构疲劳损伤的主要因素,而GPS能够为实际载荷谱提供准确的数据支撑,同时其在载荷谱外推及虚拟迭代技术中具有不可替代的作用。GPS技术的应用大大节约了试验成本,缩短了试验时间。
Expound the characteristics and application status of GPS and explain its advantages in reliability application of agricultural equipment. In the process of research on reliability, actual load spectrum, S-N curves and linear cumulative damage theory are the main factors for calculating structural fatigue damage, GPS can provide accurate data support for actual load spectrum. At the same time, GPS plays an irreplaceable role in the extrapolation of load spectrum and load iterations. The traveling trace can be restored by using Google Earth map. The application of GPS reduces the test cost and shortens the test time for enterprise.
