    Dynamic simulation and test research of impact

    1/1/2014· Dynamic simulation and test research of the impact mechanism were carried out. Dynamic simulation is realized by numerical calculation based on the mathematical model. Two types of hydraulic rock drill YYG138 and YYG150 are tested on the horizontal stand. The numerical results are basically consistent with test results.

Numerical simulation of the dynamic impact breakage

By improving the simulation of breakage in numerical models it should be possible to optimise the fragmentation process in terms of both energy input and product size range produced for a wide range of rock fragmentation processes. Other authors have studied the dynamic fragmentation process in a number of contexts. General dynamic fragmentation papers are presented by a range of authors [4

Full-Scale Impact Test and Numerical Simulation of a New

A full-scale buffer unit was designed, and two impact tests, with an impact energy of 25 kJ and 50 kJ, respectively, were conducted in succession to study the impact-resilient characteristic of the structure combined with numerical simulation. The dynamic responses of the buffer structure, including force, deformation, and energy dissipation, were analysed in depth. Finally, simple approaches

Full-scale impact test and numerical simulation of a new-type resilient rock-shed flexible buffer structure . By ZX Yu, L Zhao, LP Guo, YP Liu, C Yang and SC Zhao. Cite . BibTex; Full citation; Abstract. Rock sheds have been widely used to protect against rockfall. Traditionally, a cushion layer is placed on the top of a rock shed to reduce the impact force and dissipate energy. However, heavy

Charpy impact test Wikipedia

The Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture. Absorbed energy is a measure of the material's notch toughness. It is widely used in industry, since it is easy to prepare and conduct and results can be obtained quickly and cheaply. A disadvantage is that some

Impact Crusher Working Principle

19/4/2018· An example of gravity impact would be dropping a rock onto a steel plate (similar to what goes on into an Autogenous Mill). Dynamic impact could be described as material dropping into a rapidly turning rotor where it receives a smashing blow from a hammer or impeller. Attrition crushing is the reduction of materials by rubbing; primarily a grinding method. Shear crushing is accomplished by

Monte Carlo Simulation: What Is It and How Does It Work

Monte Carlo simulation performs risk analysis by building models of possible results by substituting a range of values—a probability distribution—for any factor that has inherent uncertainty. It then calculates results over and over, each time using a different set of random values from the probability functions. Depending upon the number of uncertainties and the ranges specified for them
