Numerical Simulations and Experiments on Single-Tooth Rock-Breaking

نویسندگان

چکیده

The rock-breaking efficiency of a drilling tool directly affects the production costs and progress foundation construction. It is essential to understand mechanism mechanical improve efficiency. In this study, dynamic simulation research was carried out on drill bit based LS-DYNA platform. Additionally, influence rotational speed spindle feed rate force in process obtained. vibration also analyzed. content presented theoretical verified through experiments. following conclusions were drawn: first, reaction that rock has presents law according different types parameters. With increase speed, axial decreases. rate, increases. effect type nonlinear. Second, during rock-breaking. When amount constant, transverse slows down, intensifies as increases, down intensifies. results provide basis for selecting parameters improving

Numerical Simulations of Laboratory Experiments for Determining the Post-yielding Mechanical Parameters of Soil and Rock

ABSTRACT: The mechanical parameters of constitutive equations for soil and rock can be determined by laboratory experiments in which a cylindrical specimen is commonly tested under uniaxial and triaxial compressive conditions. The distribution of stress in the specimen during the tests must be kept uniform and homogeneous. In this paper, numerical simulations are carried out to determine the di...

Numerical simulations and cutting experiments on single point diamond machining of semiconductors and ceramics

This chapter presents numerical simulation work and single-point nano-machining experiments conducted on semiconductor and ceramic materials, e.g. silicon (Si) and silicon carbide (SiC). The apparent ductile mode material removal mechanism observed in these materials is believed to be the result of a high pressure phase transformation (HPPT), which generates a small Correspondence/Reprint reque...

Comparison between Numerical Simulations and Experiments for Single Point Diamond Turning of Silicon Carbide

Single Point Diamond Turning (SPDT) experiments conducted on single crystal 6-H Silicon Carbide (SiC) has shown chip formation similar to that seen in the machining of metals. The ductile nature of SiC is believed to be the result of a high pressure phase transformation (HPPT), which generates a plastic zone of material that behaves in a metallic manner. This metallic behavior is the basis for ...
