表1列出了在恶劣条件下使用的56台各种型号的推土机柴油机破坏时工作时数的分布状态。从这些资料中可以获得在决策中有助于管理部门的许多信息。下面用可靠性工程中熟知的概念进行详细分析。数据的分布状态表1为由司机工作时间卡针计算的记录时数而获得的分布状态。工作时数分成十四级,每级1000小时。一般,级之间隔应该是设备预防维修期的倍数。可 Table 1 lists the working hours of 56 sets of bulldozer diesel engines under harsh conditions. Much of this information is available to help manage the sector in decision-making. The following is a detailed analysis of the concept of reliability engineering. Data Distribution Status Table 1 shows the distribution status obtained from the number of recording hours counted by the driver’s working time card. Hours divided into fourteen, each level of 1000 hours. In general, the interval between levels should be a multiple of the equipment’s preventative maintenance period. can
