However, this method can only be performed when the equipment is stopped. Repeated shutdowns of the fault simulation equipment can reduce its service life. Moreover, each adjustment requires disassembling and reassembling the bearing housing, which is complicated and the simulation effect is not obvious. Utility Model Content

[0008] The aforementioned adjustable support stiffness bearing housing for fault simulation has an adjusting bolt threadedly connected to a clamping cover plate, with the bottom end of the adjusting bolt contacting a boss on the bottom side of the bearing housing body.

[0009] The aforementioned adjustable support stiffness bearing housing for fault simulation includes a clamping cover plate comprising two horizontal plates arranged in parallel with staggered vertical alignment and a vertical plate connecting the two horizontal plates. The clamping cover plate has a Z-shaped bent structure. An adjusting threaded hole for threaded connection with an adjusting bolt is provided on the upper horizontal plate, and a through hole is provided on the lower horizontal plate. A fastening bolt for connection with the bearing base is installed in the through hole.

[0010] The aforementioned adjustable support stiffness bearing housing for fault simulation has mounting holes on the bearing base for connecting the bearing base to a corresponding mounting platform, and also has threaded holes for fastening bolts for threaded connection with fastening bolts.
