As to the failure of the condensator's crust in the system of cold circulation in a enterprise, mechanical evaluations of the maximal water press of the condensator's crust were conducted via the simplified theoretical model and the finite element numerical computation, according to the relationship of the corresponding unisonous deformation beteween the long fixed bolts on the condensator's crust and themselves. The results show that the structural design of the condensator's crust and the w...
