The utility model relates to a transmission line gold utensil vibrationfatigue test device. It is including hanging mechanism and excitation mechanism. It includes the suspension line to hang the mechanism, the suspension line is used for hanging establishes the gold utensil that awaits measuring. The excitation mechanism is used for the drive the suspension line vibrates in predetermineeing vibration frequency and predetermine the vibration amplitude range. Foretell transmission line gold utensil vibrationfatigue test device, the gold utensil that will carry out vibrationfatigue test is hung and to be established on hanging the suspension line of mechanism, then through the sustained vibration in predetermineeing vibration frequency and predetermine the vibration amplitude range of excitation mechanism drive suspension line, can await measuring the gold utensil on transmission line and receive the actual operational environment of external force vibration in order to be used for the simulation, thereby alright in order to test assay to the gold utensil in the strain degree under the vibration condition, it to provide reliable foundation for the safe operation of transmission line gold utensil to make.
