VIBRATION EXPERIMENT OF COAL SHEARER CUTTING UNIT GEARBOX HOUSING IN OBLIQUE CUTTING

open access: yesJixie qiangdu, 2020
Oblique cutting is a working condition in fully mechanized mining whose main task is making it possible for long wall shearer to cut the coal seam,and it is a harsh working condition since the shearer is forced to be bent.

An Investigation into Orthogonal and Oblique Cutting Processes [PDF]

open access: yes, 2019
The cutting process may be divided into two major types. The one type is called as straight angle cutting, where blade is in continuous contact with metal sheet from one side of edge to another side of the edge at the beginning of the cutting process. The another type is known as shearing, where the blade edge is oblique and progressively proceed from ...

Soil-Cutting Simulation and Test of Oblique Rotary Tiller [PDF]

open access: yes, 2012
A virtual prototype of oblique rotary tilling based on SPH(Smooth Particle Hydrodynamics) was developed. Digital simulation and field test of oblique rotary tilling were conducted. The digital simulation suggested that soil mainly was torn to failure during oblique rotary tilling. Therefore, oblique rotary tilling could save energy.

An experimental research of dynamic characteristics for long wall shearer cutting unit gearbox in oblique cutting

open access: yesInternational Journal of Coal Science & Technology, 2020
Oblique cutting is a working condition in fully mechanized mining whose function is making it possible for coal shearer to cut coal wall. Coal shearer often exhibit large vibration amplitudes in oblique cutting since the shearer is forced to be bent.
