Abstract

Summary The purpose of the research: implementation in Ukraine of the technical requirements of the Delegated Regulation of the EU Commission 2015/68 on the parameters of pneumatic braking systems of agricultural trailers by preparing a methodological and technical base. Research methods: research was conducted in accordance with the methods specified in Commission delegated Regulation (EU) 2015/68, 2015; SOU L. Pohorilyi UkrNDIPVT 01.1-37-04604309-008 and DSTU 1.5. The main indicators of the effectiveness of the pneumatic braking system of the trailer, which must be determined during the conformity assessment tests, are: the effectiveness of the braking system during cold brakes (type 0 test); loss of braking system efficiency with heated brakes (type 1 test); effectiveness of emergency automatic braking; brake activation time; capacity of energy storage devices. Research results: To conduct testing of the pneumatic brake system of the trailer at L. Pohorilyi UkrNDIPVT developed, manufactured and adjusted a pneumatic braking simulator that would replace a tractor to actuate the braking system of a trailer, and serial measuring equipment was used. As a result of the work carried out, the operating manual «Brake-1. Efficiency of the braking system»; developed, agreed and approved standard of L. Pohorilyi UkrNDIPVT «Agricultural machinery. Pneumatic braking systems of agricultural trailers. Test methods». The research results were implemented during tests for the European type approval of agricultural trailers produced by VARZ LLC. Conclusions. The developed methodical and technical bases contribute to the implementation in Ukraine of the technical requirements of the Delegated Regulation of the EU Commission 2015/68 on the parameters of pneumatic braking systems of agricultural trailers and make it possible to carry out testing of the equipment of domestic manufacturers without taking them outside Ukraine and to receive certificates of approval of the type of the European sample. Keywords: agricultural trailers, pneumatic braking system; testing; braking simulator; type approval certificate.

关于在乌克兰实施欧洲方法测试农业拖车气动制动系统的问题
研究目的:通过准备方法和技术基础,在乌克兰实施欧盟委员会2015/68授权法规关于农业拖车气动制动系统参数的技术要求。研究方法:根据欧盟委员会授权法规(EU) 2015/68, 2015中规定的方法进行研究;苏林。波霍里伊。乌克兰。ndipvt . 01.1-37-04604309-008和DSTU . 1.5。在合格评定试验中必须确定的拖车气动制动系统有效性的主要指标是:冷制动(0型试验)时制动系统的有效性;加热刹车时制动系统效率损失(1型试验);紧急自动制动的有效性;制动激活时间;储能设备容量。研究结果:为了在L. Pohorilyi UkrNDIPVT进行拖车气动制动系统的测试,开发、制造和调整了一个气动制动模拟器,该模拟器可以代替拖拉机驱动拖车的制动系统,并使用了串行测量设备。由于所进行的工作,操作手册«Brake-1。制动系统的效率»;制定,商定和批准了L. Pohorilyi UkrNDIPVT农业机械标准。农用拖车气动制动系统。测试方法。”研究结果在VARZ有限责任公司生产的农用挂车欧洲型式认证试验中得到了实施。开发的方法和技术基础有助于在乌克兰实施欧盟委员会2015/68关于农业拖车气动制动系统参数的授权法规的技术要求,并使其能够在不将其带到乌克兰境外的情况下对国内制造商的设备进行测试,并获得欧洲样品类型的批准证书。关键词:农用挂车;气动制动系统;测试;制动模拟器;型式认可证书。
