Abstract


Given the extensive power vibrating plate compactor market demand and potential applications that require high power vibratory plates have good adaptability and reliability , which gives the plate compactor design made ??requests. In order to provide theoretical support to the design calculations , in -depth study of this vibrating plate compactor power structure based on the principle of one of the key techniques are studied . Finite element analysis theory to software UG and MSC.Nastran software as a platform for key components of reliability analysis . The results and material allowable stress compared to verify the structural design is reasonable and material selection reliability. This paper established a vibrating plate compactor - mathematical model of the soil , the mathematical model using MATLAB programming and simulation solution , obtained vibrating plate compactor working dynamic response. According to results from the theoretical analysis for solving plate compactor damping block the causes of damage and identify the relative displacement of the upper and lower plate and the upper plate size centroid deviation , vibration block stiffness, damping block installation angle relationship between the proposed measures to avoid damage damper . The use of high-power indoor soil bin vibratory plates acceleration tests carried out to study the characteristics and the work plate compactor vibration parameters , by changing the excitation frequency and damping stiffness of the system has been up and down plate acceleration and relative displacement distribution of the proposed flat rammer reasonable working frequency and damping stiffness of the system for subsequent product design provides an important theoretical basis.
