近十余年来,矿井提升设备的设计方法有了引人注目的新趋向,主要是计算方法日益合理化和精确化。不仅要求对设备的外载荷、内应力的计算要精确,结构要合理,并且开始要求对构件的使用寿命能有一个比较切合实际的计算方法。这样,就迫使设计人员从经验类比、概算、校核和天才的猜想的传统圈子里走出来,运用 In the past ten years or so, there has been a remarkable new trend in the design of mine hoisting equipment, mainly due to the increasingly rational and precise calculation methods. Not only requires the external load on the device, the calculation of internal stress should be accurate, the structure should be reasonable, and began to require components of the service life can have a more realistic calculation method. In this way, designers are forced to come out of the traditional circle of empirical analogies, estimates, checks, and guesses of genius
