    Abstract

    To reduce trailing noises mixed in ultrasonic echoes during ultrasonic wave propagation in a buffer rod, the influence of the rod’s boundary shape and dimension on the signal-to-noise ratio (SNR) was analyzed using a simulation method. Novel buffer rods with complex structures and shapes based on a cylinder or cone reference surface were proposed. The novel rods were found to be more effective in obtaining signals with high SNR than the cylinder or cone rods currently in use. Simulation results showed that the rod proposed in this paper exhibited better performance in a given installation space compared with the cylinder or cone rods.
