我国自行设计研制的十立方米挖掘机和一百零八吨电动轮自卸车于今年九月廿七日在首钢通过了国家级鉴定.这次通过鉴定的四辆SF3102型电动轮自卸车,首次装用了由我校汽车教研室主任黄天泽教授等同志与湘潭电机厂共同研制的防寒驾驶室.抚顺煤矿研究所、湘潭电机厂和我校等三单位组成的性能抽查复测小组,对被鉴定的样车进行了部分性能抽测.测试结果表明:新型防寒驾驶室室内噪声为77.8dB,比原驾驶室83dB降低5.2dB,降噪效果明显.新驾驶室正前方盲区距离为4m,比原驾驶室5.5m减小1.5
China’s own design and development of 10 cubic meters of excavators and 108 tons of electric wheel dump truck in Shougang passed the national appraisal on September 27. This passed the identification of four SF3102 electric wheel dump truck for the first time Fitted with a cold cab by Professor Huang Tianze, director of the Automotive Teaching and Research Division of our school and the cold cab developed jointly by Xiangtan Electric Machinery Factory.An investigation team of performance random sampling composed of three units including Fushun Coal Mine Research Institute, Xiangtan Electrical Machinery Factory and our school, The test results show that: the new cold-proof cab interior noise of 77.8dB, 83dB lower than the original cab of 5.2dB, noise reduction effect is obvious.The new cab in front of the blind spot distance of 4m, 5.5 than the original cab m decreases by 1.5
