Abstract: It is proved that the load position determination is the baes of the cross-talk elimination of a multicomponent force sensor under the condition of load position unfixed. A new method for recognizing on the base the sensor's out-put is developed by applying pattern recognition technique in load position .The problems of feature extraction, pattern pre-process and classification rule choice are discussed.Lastly, a practical example is given. The new method is proved of effective on load position determination and the sensor's cross-talk is greatly reduced.

Key words: multi-component force sensor, computer simulation recognition, interference
