基于 ADAMS 的纵轴式掘进机纵向振动的仿真研究
Simulation and study of vertical vibration for longitudinal roadheader based on ADAMS
摘要
Abstract
In order to find out vertical vibration characteristics of a longitudinal roadheader and improve the reliability of its work -ing,a multi-body dynamics model of the longitudinal roadheader is established according to the theory of multi -body dynamics . Through analysis loads of cutting head and between track and base ,and modal analysis ,the system modal vibration shape is ex-tracted and the frequency response diagram of the system vibration is drawn .For further exploring the vibration characteristics ,the effect on the vibration of machine is researched by using of computer simulation of the hydraulic systems damping ,the changing of cutting head and body stiffness and mass ,and vertical vibration characteristics of the geometric center of three test points of cut -ting head,cantilever and body are acquired .The results show that the vertical amplitude of cutting head and cantilever are re -duced by 38%and 20%when the body ’ s mass increases 5%;as the damping of the hydraulic system increase 20%,the vertical amplitude of cutting head ,cantilever and body are decreased by 33%,12%,10%;and the amplitude of cutting head and cantile-ver are decreased by 35.8%,25%when the stiffness of the body is doubling .The conclusions provide a theoretical basis for fur-ther analysis of the vibration characteristics of roadheader .关键词
