The guide rail of the working device of the road drilling machine is prone to shock vibration during the working process,which may lead to fatigue failure of the guide rail.Therefore,it is very important to study the structure,natural frequency and mode shape of the guide rail device of the road drilling machine.A 3D model of the guide rail is established by using SolidWorks,and the modes of the guide rail were analyzed by ANSYS Workbench under the working conditions of power head and hydraulic hammer,and the natural frequency and mode shape contour of the first 8 orders of the guide rail were calculated.The simulation results show that the structure of the guide rail can effectively prevent the resonance during the driving process and the power head and hydraulic hammer during the work,and provides theoretical support and practical reference for the subsequent multi-order modal analysis and structural optimization.
