Abstract:
To study the relationship between the mechanics and structure parameters in the process of static rotary penetration,the experiential formula of rotated penetration to concrete is established based on the classical theory of the cutting.LS-DYNA is used to simulate the process.Simulation experiments on static rotated penetration to concretes are done with orthogonal experiments.The Levenberg-Marquardt arithmetic is used to fit experiential formulas.The experiential relations of the force,torque,diameter,feed level and circumrotation are established.The results show:the experiential formulas follow the simulation results well,the diameter of the rotary penetrator influences the force greatly,the feed level influences the torque greatly,and the circumrotation influences the force and the torque little.
