It can individually adjust height.
Generally in use, totally two sets of charging assembly of bending, two sets of bending charging assemblies are by crew module, before crew module
The placement of standdle carrier body is distinguished afterwards；Positioned at front bending charging assembly two reinforcings cone 5 be loaded into two of white body 1 respectively before
It arranges on seat, two reinforcing cones 5 of the bending charging assembly being located behind are loaded into two back seats of white body 1 respectively
On.
For certain special vehicles, it is only necessary to which a set of bending charging assembly, bending charging assembly pass through crew module's standdle carrier body
Placement, the two reinforcings cone 5 for being bent charging assembly are loaded between the front-row seats and back seat of white body 1 respectively, are bent
After the loading beam 8 of charging assembly horizontally rotates and equalizer bar 10 is in angle, to avoid the B column of white body 1, avoids occurring with B column
Interference.The relatively flat balance beam 10 of loading beam 8 can be arranged if necessary with certain angle, increase the scope of application of loading device.
Before on-test, need to adjust the operating position of white body bending stiffness loading device for testing：Firstly, transmission rod is total
At alignment white body longitudinal axis；Secondly, reinforcing cone falls in front seats and back seats passenger riding position；Again, loading beam and equalizer bar
It is adjusted to level, equalizer bar also needs to be adjusted to horizontally-parallel with white body；Finally, reinforcing cone is set to zero with white body gap.When
When intermediate altitude not enough installs bending charging assembly in white body, the height of left and right lifting support assembly is adjusted.
When on-test, the force value display system of force snesor is opened.Then, by requirement of experiment, left lifting support is rotated
The adjusting sleeve (or screw lift of right lifting support assembly) of assembly pulls the rotation of loading beam vertical direction, power is passed
Transmission rod assembly is passed, force value is loaded to force value display system by the force snesor output installed on transmission rod assembly, thus
Control the operation of load and the size of loading force.Required loading force passes through equalizer bar again and is assigned to reinforcing cone, passes to white vehicle
Body realizes load.
