Abstract: Based on the analysis on the generation factor of a parasic power in the doutble axle drive vehicle the kinenatcs equation and parasticpower judgement fomul/a of the double axle drve vehicle were derived ,the judgement was conducted on the fiow direction of the parasitic power and a quantiative calculation methodof the parasitic power and thecontroltatics to elininate and reduce the parcstic power were further provided.n combination with the whole vehicle parameters of thedouble axle drive vehicle a NATLAB sofiware was appied to write the calculation program.An analysis calculation was conduced on the WC5E(B) mine explosion profrcklss uboer tye vehicle as a case. The paper verifed caculato methods mentioned in the papes, meanwhil ,the wireless remote signal monitoring and analysis system was applied to comparison and anaysi test.The resuts showed tht the method cou d well make quantitative analysis and calculation on the parcastic power ofthe double axle drive vehicle.
