Hydraulic support is an important equipment for coal mine production,and its design and manufacturing level directly affects the safety production and economic benefits of coal mine.Taking ZT6500/19.5/34 hydraulic bracket as an example,the 3D solid model of the simplified hydraulic bracket prototype and its 1∶5 model was established by using 3D modeling software SolidWorks,and the 3D solid model was imported into ANSYS software,which was used to carry out a strength test under the base torsion condition of the prototype of this type of hydraulic bracket and its 1∶5 model.The corresponding total displacement distribution law and equivalent force distribution law of the simplified hydraulic support prototype and its 1∶5 model were found,and the proportional relationship between the total displacement and equivalent force of the simplified hydraulic support prototype and its 1∶5 model was determined.
