When row aerostatics typical case's connector strength test, testpieces is tensioned by the way of manually adjusting, complicated for operation, efficiency
Lowly, and there is no Special test rack, since the randomness installed every time causes test repeatability poor.The experimental rig passes through
The ball-screw of transverse and longitudinal both direction adds servo motor and control program, realizes the auto-tensioning of testpieces, quick for installation, easily
It is reproducible in operation.
2, the experimental rig can be realized the tensioning of twin shaft fast quantification；The experimental rig on mounting plane by being arranged phase
Mutually vertical twin shaft tensioning apparatus, may be implemented the tensile force synchronous tension on planar biaxially oriented by setting, preferably
Applying working condition under simulation test piece installation state.
3, the experimental rig can satisfy testpieces of different sizes, universal relatively strong；The experimental rig can meet centainly
The test demand of different size testpieces in range.
4, the experimental rig can satisfy the load demand of different angle；The experimental rig can be quickly real by pulley system
The demand of existing multi-angle load.
5, it is adjustable to can be realized loading speed for the experimental rig；The experimental rig is by process control for the electronic of load
Cylinder meets requirement of the testing standard to loading speed, it can be achieved that rate of extension accurately controls.
6, the experimental rig can be automatically controled, and realizes the automation of test installation and load, test efficiency is greatly improved.
The experimental rig is all carried out automatically controlling using program from load is installed to, test efficiency is greatly improved.
