Abstract: To solve the quantitative evaluation problem of gunner operating posture in the process of artillery aiming,loading,repairing and march-combat conversion,a comprehensive evaluation model was constructed from the top-down at the application layer,performance layer,logic layer,data layer and knowledge layer based on the multi-index dimensions,which was relied upon the human-machine simulation technology.In the right of the evaluation data analysis part,the gunner position assessment data analysis system named DASGOPE 1.0 was developed by combining with Grey Relation Analysis(GRA),Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS),grey relation closeness and grey relational clustering.The operation evaluation of handwheel of a certain type of towed howitzer aiming mechanism was taken as an example to discussed the application of the proposed model.The digital model of gunner's body and design scheme for handwheel were constructed.The dynamic behavior process of gunners was simulated,and the operating posture was evaluated by eight indexes of wrists,elbow,trunk,hip,knee and ankle.The evaluation data of DASGOPE 1.0 was calculated and processed,and the research showed that the evaluation model was available.Aiming at the groups of artillery human-machine control equipment design scheme,the optimal or suboptimal scheme was quickly identified and extracted by evaluating the rationality of the corresponding behavior posture,which could provide guidance for the subsequent control equipment optimization.
