Abstract：The sliding electric contact can be considered as a current-passing tribosystem with coupling action,and the contact state is influenced by many factors. It is the method to find the best contact load,which makes both of the contact resistant and ratio of wear least. For the conflict of the both,the Pareto meaning is given in the multi-object,and some definitions are given too. Then some experiments about the sliding electrical contact on the designed machine were done. With the data,whose inputs are running velocity,current and contact load,and outputs are contact resistant and ratio of wear,and the black box model using the neural network is trained. So a multi-objective artificial fish arithmetic is proposed to optimize the model to minimize the contact resistant and ratio of wear. At last the contact load is obtained in the giving condition,which shows the validity of the arithmetic.
