Study on Structural Stress and Optimisation of Hydraulic Support Roof Beam under Partial Loading Condition
Taking ZY29000/45/100D hydraulic support as the research object,ANSYS and ADAMS software are used to study the reliability of hydraulic support,through the stress-strain analysis of the whole machine,it is found that the stress value is larger in the main reinforcing plate,the pin hole of the main reinforcing plate of the roof beam and the connection of the tail cover plate,therefore,the structural size optimization is carried out for the larger stress points,and the stress on the roof beam is significantly improved after optimization,the maximum value is smaller than the yield limit of the material,and the rigidity of the structure is improved.After the optimisation,the stress on the roof beam has been significantly improved,the maximum value is less than the yield limit of the material,the stiffness and stability of the structure have been greatly improved,and the optimisation plan is feasible.
