摘　　要： 机床中的工作台或工作平台是一种具有强横隔的单箱或多箱室结构,以往的设计都凭经验而确定,容易造成材料的浪费或刚度不足等现象。本文试图从理论上来解决此类结构的设计计算问题。通过实例的计算与测试,本文提出对具有强横隔的箱室结构,其内力计算可先按肋梁的荷载分配系数决定各肋梁荷载,再由各单肋梁相应截丽的内力计算值而确定的计算方法,能够较准确地反映实际情况。可供设计人员参考。 The working table of a machine tool is a kind of single or multiple box-construction with strong transverse partition plates.The design of which is determined by experience in the past,which results in a waste of materials or an in sufficience in rigidity.In this paper,the authors try to solve the calculation problems of the construction designs theoretically.Through the calculations and tests to some examples,this paper provides a calculation method for the box-construction with.strong transverse partiton plates.The internal force can be determined first accord-ing to the load of each rib fixed by the coefficient of load distri-bution and then to the calculated value of the internal force of the cross-sections relative to each single rib.The result can accurately reflect the actual conditions.And this paper can be used as a gui-dance and a reference to the designers.
