Design and Simulation Analysis of a Small Mobile Vibratory Equipment
摘要
Under the general trend of ‘Carbon Peak and Carbon Neutrality’ in China, the wind power market is developing rapidly and the number of wind turbine installations is rising year by year. The foundation of the wind turbine is the fixed end of the wind turbine, and the quality of the foundation directly determines the stability and safety of the wind turbine, and the concrete vibration technology is an important part of the foundation construction. For the traditional manual operation of concrete vibration, there is a certain safety risk which causes vibration disease to the health of construction. In this study, a small mobile vibratory equipment is designed, which has the functions of image return and remote control. The equipment includes a flexible shaft expansion structure, a screw lift structure, a steering structure, and a track structure. In addition, the kinematic characteristics of the equipment were analyzed by establishing the D-H parametric model of the equipment and analyzing the solution of its forward and inverse kinematics. Based on the ANSYS Workbench simulation platform, static and vibration modal simulations were carried out to ensure that the static strength of the device structure meets the working requirements and does not resonate with the vibrator, which ensures the reliability of the device. Although the background of the development of this equipment is for the construction of wind turbine foundations, it is also applicable to construction scenarios such as concrete pavements and bridge abutment foundations that meet the requirements of equipment track erection.
