陕西省金属结构厂研制生产的JS-1型建设牌翻斗车,在国内外用户中得到普遍的好评。尤其是新产品JS-lj型,增加了驾驶棚,自翻及机械回斗机构,驾驶员座椅上增添了减振器及弹簧、减少车辆振动,改善了劳动条件。为了了解该类车辆振动情况,西北农学院与厂方一起于80年12月至81年7月,对JS-1型,JS-lj型及进口的意大利P.G.S型,西班牙AUSI型四种翻斗车进行了振动测试。由于国家没有颁布正式的试验大纲,本试验的项目及要求,系根据试验条件研究制定的。一、测试方案及实施车辆在工作中由于地面的高低不平,发动机和传动系统的激励而引起的振动,是通过驾驶员的座椅而传递到驾驶员身上的。根据有关资料,决定人体对振动的反应有四个重要
The JS-1 construction brand dump truck developed and produced by the Shaanxi Provincial Metal Structure Factory has been widely praised by users at home and abroad. In particular, the new product, JS-lj, has increased the driving shed, self-turning and mechanical reversal mechanism, added shock absorbers and springs to the driver’s seat, reduced vehicle vibration, and improved working conditions. In order to understand the vibration situation of this type of vehicle, the Northwest Agricultural College and the factory together in December 1980 to July 81, the JS-1 type, JS-lj type and imported Italian PGS type, Spanish AUSI type four dump trucks Vibration testing was performed. As the country has not promulgated a formal test program, the project and requirements for this experiment are based on experimental conditions. First, the test program and the implementation of the vehicle in the work due to the uneven level of the ground, the vibration of the engine and transmission system caused by the vibration, is transmitted to the driver through the driver’s seat. According to the relevant data, it is important to determine the body’s response to vibrations.
