Calculation study of heater plateCalculation procedureTwostage calculation was performed:
As a result of calculation of heating conditions, temperature fields were determined. These fields were used as a load for the calculation of tensedeformed state. Calculation of heating conditionsPotential difference in current leads was defined as a load in the calculation of heating conditions. The process is not stationary. Time change of temperature due to tension was monitored.
Calculation of tensedeformed stateTemperature fields determined in the calculation of heating conditions were used as a load in the calculation of tensedeformed state.
ConclusionsThe calculation showed that tension in the heater exceed the ultimate strength. This results in damage to the heater according to the results of experiment. To ensure operability of the heater in all conditions it is necessary to change its geometry or to use the heater made from a different material. A range of special calculations is needed to determine an optimal geometry with the use of different materials. Hexa Company, 2006
