It is even be applied to drivers' cab to be tested it is complex-curved on, realize then the test of static strength complex-curved to drivers' cab.
Based on same inventive concept, present invention also offers a kind of drivers' cab curved surface test of static strength loads the system of frock
Make method, comprise the following steps：Step one, determines the shape of the loading area housing of curved surface to be tested using projection form cutting；
Step 2, makes loading frock body according to the shape of loading area housing and pours mould, by mould and curved surface phase to be tested
To fixation, strong concrete is poured into into mould by the sprue gate on mould, maintained 24 hours with water, form test of static strength
Loading frock body.
Adding for suitable any irregular complex curved surface loading can fast and effeciently be produced using the method for the invention
Carry frock, it is ensured that big load being capable of smooth uniform load.
Used as a kind of optimal way, the projection form cutting includes：Curved surface to be tested from three-dimensional drawing is intercepted and led
Go out single diagram of block, diagram of block is projected along loading force direction, the loading area of curved surface to be tested is obtained
The shape of housing.
Based on same inventive concept, present invention also offers a kind of drivers' cab curved surface test of static strength device, including load
Lotus applying mechanism and described test of static strength loading frock, the load applying mechanism are connected with loading frock body.
By said structure, to be tested curved surface apply uniform load by loading frock using load applying mechanism, it is real
Now complex-curved to drivers' cab test of static strength.
Used as a kind of optimal way, the load applying mechanism includes reaction frame and at least one be fixed on reaction frame
Loading chain, the loading chain include oil cylinder, and oil cylinder is connected with reaction frame, and the piston rod of oil cylinder is connected with loading frock body.
Oil pump of the oil cylinder using outside provides loading power, by the piston rod of oil cylinder and loading frock to curved surface to be tested
Imposed load.
Further, the loading chain also includes load transducer, and the piston rod of oil cylinder is by load transducer and loading
Frock body is connected.
Load transducer is used for the size for monitoring loading force, loads dynamics with precise control.
Used as a kind of optimal way, the number of the loading chain is two, and the load applying mechanism also includes being installed in
Horizontal gird on reaction frame, the two ends of crossbeam respectively connect a loading chain.
Further, loading chain also includes articulated mounting, and oil cylinder is connected with crossbeam by articulated mounting.
Articulated mounting causes entirely to load two power bar of chain formation, it is ensured that loading is not because being loaded object bending and unstability.
Further, also including constraint seat and adjusting screw, one end of the adjusting screw and the bottom of loading frock body
Face is hinged, and the other end and the constraint seat of adjusting screw are hinged.
By the position relationship for adjusting constraint seat and the relative loading frock of adjusting screw and reverse frame, can be added with Auxiliary support
Carry frock and constrain loading frock and move along curved surface to be tested（As curved surface to be tested is subject to horizontal force, downward dividing can be produced
Power, makes to be loaded drivers' cab generation flexural deformation, is subject to counter-force effect upwards move so as to load frock, and movement can make to add
Frock unstability is carried, so as to load cannot be made to be loaded on curved surface to be tested）, it is ensured that loading is smoothed out not unstability.
The present invention ensure that loading force is uniformly applied to the complex-curved above and not unstability of drivers' cab to be tested, and it is right to realize
The complex-curved test of static strength of drivers' cab, it is adaptable to any irregular complex curved surface, it is ensured that big load can be smoothly uniform
Loading.
