Abstract: The lifting device prototype is developed to realize the transportation of tungsten alloy balls. The tungsten alloy balls are new targets used in the accelerator driven subcritical system(ADS). The basic principle is the electromagnetic force of the solenoid. Controlling the power-on and power-off time of a group of solenoids can achieve the movement of magnetic field. The magnetic field acts on the targets to complete the transportation of alloy balls. The solenoid is the main component of the device and its structure should be beneficial to lifting the targets. Ansys Maxwell is used to analyze the distribution of magnetic field for solenoid to determine the structure of the solenoid. It is also used to accomplish simulation at different pulse width for each solenoid. Power-on time and power-off time of each solenoid and the number of solenoids working simultaneously are regulated to simulate the force of alloy ball. Based on the numerical analysis, the processing and experiments of the device prototype have been finished. The results show the device prototype has achieved the desired effect of tungsten slloy ball transportation.
