当前电子计算机已被广泛地应用于工农业生产和科学研究的各个领域。以电子计算机解题为特色的有限元法自五十年代以来迅速发展,不少过去无法计算的问题,找到了新的计算方法,以往为了便于手算必须简化、甚至误差较大的问题,现在可以进一步作精确研究了。这充分显示了用有限单元法解题速度快、精确度高、有利于多种方案比较,大大节省了人力和时间,具有巨大的优越性。矿井提升机是矿井运输中的咽喉设备,是井下与地面联系的唯一工具。它的状况如何,直接关系到生产的正常进行和人身安全。提升机卷筒是矿井提升机的主要承载部件,它的作用是缠绕钢丝绳,承担全部提升负荷,进行动力传递,完成提升矿石、人员、设备的任务。据有关部门的调查,国内使用期限达十年以上的提升机80%发现有卷筒开裂、塌陷、开焊或联接螺钉剪断等现象,这除了使用和制造方面的
The current computer has been widely used in various fields of industrial and agricultural production and scientific research. The finite element method, which is characterized by solving electronic problems, has developed rapidly since the 1950s. Many of the problems that can not be calculated in the past have found a new calculation method. In the past, in order to facilitate the calculation, the finite element method Can be further accurate research. This fully shows that using the finite element method solves the problem fast, high accuracy, is conducive to the comparison of a variety of programs, saving manpower and time, with great advantages. Mine hoist is the throat equipment in the mine transportation, which is the only tool that connects the mine with the ground. Its status is directly related to the normal production and personal safety. Hoist drum hoist is the main bearing component of the mine, its role is to wind the rope, to undertake all the lifting load, the power transmission, to complete the task of upgrading ore, personnel, equipment. According to a survey conducted by relevant departments, 80% of hoisting machines with domestic service life of more than 10 years were found to have phenomena such as reel cracking, collapse, open welding or joint screw cutting, which, apart from the use and manufacture
