Reliability Of Cutting Test Bed Of Road Header

Test Bed of Road Header is very important in the development of Road Header , existing mathematics and mechanics model is hard to describe road header tunneling process structure and the change of mechanical parameters ,and in construction field , physical prototype test will lead economic costly and take the very high technology security risks . Therefore, establishing Cutting Test Bed of Road Header is an effective means to improve the reliability of the system road header.This paper based on the mechanical design theory of determing cutting cut pieces of geometric parameters test on design and strength check , at the same time use 3d parametric software Pro/E on test-bed three-dimensional entity model in establishing this project , and through the reliability of static interference and inspection model integral design ,will test-bed as just - soft coupling many-body system, based on software interface technology and virtual prototype technology , using finite element software ANSYS software of dynamics and ADMAS for static/dynamic characteristic analysis , analysis when the different raise Angle, flat determing cutting of Cutting Test Bed of Road Header bench cut the influence , using hydraulic software module ADAMS/Hydraulies simulated test hydraulic loop, inspects the stability of hydraulic system.This research for Cutting Test Bed of Road Header and obtain a variety of transverse cutting conditions to provides a way for the prototype structure information , which helps reduce x-ct tests caused the waste of equipment and material withit has a great application prospect .
