1989年9月25～26日,在无锡召开了降低摩托车噪声科研成果评审会。该项任务是中国汽车工业联合会摩托车办公室在1988年下达给上海汽车拖拉机研究所(上海摩托车研究所)的。会议由中汽联摩托车办公室主持。参加会议的有16个单位的22名专家和专业人员。会议期间,任意抽调两台有关工厂的250型摩托车在无锡马山东坝公路上作各种工况的行驶实测试验。行驶试验和台架试验表明:各厂的250型摩托车现在的最大噪声(加速噪声)为87～88dB(A)左右,经改进后的最大噪声不大于82dB(A)(最低为79.5 dB(A)),降低了5dB(A)左
September 25, 1989 ~ 26, held in Wuxi to reduce motorcycle noise research results review. This task was assigned to the Shanghai Automobile Tractor Research Institute (Shanghai Motorcycle Research Institute) by China Association of Automobile Manufacturers Motorcycle Office in 1988. The meeting was chaired by China Automobile Federation Motorcycle Office. Twenty-two experts and professionals from 16 units attended the conference. During the meeting, 250 motorcycles of two factories were randomly assigned to make various driving tests on the Dongba Road in Mashan, Wuxi. The driving test and the bench test show that the maximum noise (acceleration noise) of the 250 motorcycles at various plants is about 87 ~ 88dB (A), the maximum noise after improvement is no more than 82dB (A) (the lowest is 79.5dB A)), reduced by 5dB (A) left
