摘要
采用原始循环机构和ICAR-CIAE开发的动力踏板，设计了一种符合人体工程学的清洁分级机。研究对象为15名男性，年龄在20-40岁之间，平均身高1640±40 mm，平均体重54±5 kg。采用次最大运动方案测定受试者的最大有氧能力。使用原始循环机构时的平均工作心率为157次/ min-1，而使用动力装置时的平均工作心率为125次/ min-1。采用循环机构蹬车时工作脉搏(ΔHR)为57次min-1, 31次min-1。与采用循环机构蹬车相比，采用动力踏板可使机器的输出能力提高41 kg h-1。与原来的循环机制相比，在清洗分级机中使用dynapod可减少51.6%的工作量。
Intervention of Dynapod in Cleaner-cum-Grader for Drudgery Reduction
An ergonomic evaluation cleaner-cum-grader with original cycle mechanism and ICAR-CIAE developed dynapod was conducted. The study was conducted with 15 male subjects aged between 20-40 years, mean stature of 1640 ±40 mm and mean weight of 54 ±5 kg. The maximum aerobic capacities of the subjects were determined using sub-maximal exercise protocol. The mean working heart rate of the subjects in operation of machine with original cycle mechanism was 157 beats min-1 as against 125 beats min-1 with dynapod. The work pulse (ΔHR) of 57 beats min-1 and 31 beats min-1 was observed for pedaling with cycle mechanism and dynapod, respectively. The output capacity of machine increased by 41 kg h-1 with use of dynapod compared to pedaling with cycle mechanism. Using dynapod in operation of cleaner-cum-grader resulted in drudgery reduction by 51.6 % as compared to the original cycle mechanism.
