摘　　要：本文就火炮手轮力对炮手工作负荷及系统工效的影响进行了实验研究。结果表明，炮手的瞄准作业工作负荷很高，各种手轮力条件下炮手的平均工作心率在每分钟１６５至１９０次之间。负荷大小不仅取决于手轮力，而且和火炮的转动惯量有直接关系。手轮力的加大会降低系统工效，即瞄准误差加大，瞄准时间增长，在手轮力降低到一定值之后，进一步减小手轮力时对炮手负荷及系统工效不再产生明显的影响。瞄准前体力负荷较大的作业会降低炮手瞄准作业能力，从而降低系统的工效。he effect of gun handwheel resistance on gunner's workload and system efficiency was studied in the presentpaper。Results showed that gunner's workload was very high when they were aiming. The average work heart rateranged from 165 to 190 beats per minute。 Gunner's workload bore direct relation to not only handwheel resistancebut also the inertia of the gun。 The system efficiency decreased as the gun handwheel resistance was raised,i.e.the aiming time became longer and the aiming error larger.After handwheel resistance was regulated down to a cer-tain level,its further decrease had no significant effect on both workload and efficiency.Work with higher work-load before aiming would result in reduced gunner's aiming performance and system system efficiency。
