Experimental Modal Test and Analysis for Auxiliary Beam of Sand Blender
Hua Jian, Zhu Hongwu, Zhou Sizhu and Zuo Yongqiang

Abstract:
The auxiliary beam of sand blender had a frame structure which was welded by profile steel, the structural feature of which determined that the natural frequencies along the vertical direction were fairly low. During the operation of sand blender, the possible equality between working frequencies of on-board devices and natural frequencies of the auxiliary beam could cause a strong vibration, not only influencing the normal fracturing, but also leading to structural damage of the auxiliary beam, jeopardizing the safety of the sand blender. In this study, the experimental modal test of the auxiliary beam was conducted by using the method of single point pulsing and multiple points receiving. The main goal of the study was to determine basic dynamic characteristics of the auxiliary beam. The working frequencies of on-board devices were calculated and the relationship between which and natural frequencies of the auxiliary beam was analyzed. The study results would provide reliable basis for modifying the structure of the auxiliary beam and adjusting the operating parameters of on-board devices aimed to reduce the vibration.
