摘要: 建立了大型机架温度场的模型。对缩小床身结构用差分法求出温度分布与试验测定值比较,得到比较一致的结果。在结构温度分布数值基础上用SAP-5软件计算出热变形量,从而初步获得一种补偿测量和形变预测的方法。

Abstract: A methmetical model of temperature field in a large machine frame is structured from which the numerical solution of temperature distribution can be obtained. The results in surface temperature distribution of a reduced scale model from the above calculation compared with that from experimental measurement are relatively indentical. Based upon these values, the thermal deformation in a structure is calculated using a structure analysis program package SAP-5. In its primary stage, a new method of form departure measurement with temperature compensation is thus obtained.
