摘　　要：为了合理地设计操作台面,使操作人员的动作快而准确又少费力气,我们对操作人员在坐姿条件下左右手的往复动作进行了分析。实念结果表明:从人体对称轴向左(右)30°至60°区域内,左(右)手操作频率最高;向左(右)外转30°区域内,左(右)手操作频率居中等;向左(右)外转60°至90°区域内,左右手操作频率较低。左右手动作准确性均在0°、90°和180°方位较差,其它方位较好,错误率曲线呈“W”形。本实验结果与美国人类工程学家斯夸尔斯(P.C.Squires)。确定的经常操作范围较为一致,可供有关部门设计时参考。For a better design of work-surfaceso as to facilitate the operator'sjob,we conducted an analysis on thereciprocating movement of both handsof the operator under seated condition.The results indicate that the left/righthand operating frequency is the highestin the area between left/right 30°—60°turning outside from body symmetricalaxis,medial between left/right 0°—30°and the lowest between left/right 60°—90°.The movement correctness of bothhands is poor at the angles of 0°,90°and 180°,but better in other directions.The error rate curve is in the shape of“W”The result of this experimentis relatively consistent with the normalworking area proposed by the Americanhuman engineering specialist P.C.Squires and can be used as a designreference.
