Make.
As shown in figure 3, the workflow of elevator door device for detecting stressed deformation of auto：Include the following steps：
It is needed to choose sufficiently long supporting rod according to scene, tightens attaching nut, adjusted vernier knob and so that supporting rod is steady
It is scheduled between lift door frame.Then force application apparatus is placed at the measurement point position chosen, locks connection buckle, it is micro- to adjust front end
Adjust surface and door good surface contact of the knob by load cell.
Suitable position is chosen, magnetometric sensor is fixed on elevator door suitable position, sensor stand is adjusted and makes displacement
Sensor front end and force application apparatus front end level of synchronization, and well contact.
Instrument fix after by the communications cable be inserted into measurement host echo port, then open measurement host enter measure it is soft
Part.
Software presses " measurement " button after starting, and interface is arranged into measurement parameter, can be according to reality in the interface
