Abstract  Accurate finite element modeling of accurate tuning unit is conductedand relationships between connecting spring, tuning bolt and matching are analyzed through equivalent modeling method. Within the range of 0-65 ℃, mechanical performance of tuning unit has been investigated and evaluated. In addition, frequency compensation principle of tuning unit under high temperature is studied. Testing results indicate that the calculation and analysis are right.
