由于机器及其零件的工作条件各种各样和对机器的使用特性及其零件的要求也很不一样,所以目前尚缺少用以研究各种机器及其零件工作能力消耗的统一的试验台和试验方法。研究各种材料和最标准共轭零件的摩擦、磨损及寿命的试验表明,必需把这些试验分成三种基本形式:实验室试验、试验台试验和使用试验。它们之间的区别取决于对机器任何共轭零件接近实际工作条件的程度。
Because the working conditions of machines and their parts are various and the requirements for the use characteristics of machines and their parts are also very different, there is currently a lack of a unified test bench to study the consumption of various machines and their parts’ working capacity. experiment method. Experiments to investigate the friction, wear, and life of various materials and the most standard conjugate parts show that these tests must be divided into three basic forms: laboratory tests, bench tests, and use tests. The difference between them depends on the extent to which any conjugate parts of the machine are close to the actual working conditions.
