Electric current calculates the output torque of driving motor 12, for example, for asynchronous AC motor, the relationship of operating current and output torque is
Tn=C × Φ × I, wherein C is constant of the machine, Φ is motor magnetic flux, TnFor output torque, I is operating current, other types electricity
The calculation method of machine also belongs to the prior art, does not repeat;Secondly, according to the output torque of driving motor 12, in conjunction with crane
Structural parameters, driving motor 12 is calculated to the driving force of crane, for example, when driving motor 12 is for driving vehicle with walking machine
When the wheel of structure 11, driving force F=Tn × i/ (D/2) of the every driving motor 12 to crane, wherein i is subtracting for reduction gearbox
Speed ratio, D are the diameter of running wheel 111.
S300, determination step, if crane continues to keep parked state, determine under the driving of driving motor 12
Specify parked mechanism that can resist setting simulation wind-force;If crane is driven to operating status, parked machine is specified in judgement
