DMH Thermal Fatigue Test System
Thermal Fatigue Test System

●Thermal Fatigue Test System

By synchronizing heat cycles with stresses cycles, this system can evaluate the effects of boundary restriction caused by thermal change. The stress cycle is given by hydraulic servo system and the heat cycle is given by high-frequency inductive heating system.
