车载式颠簸累积仪是路面平整度快速测定设备,是国家“七五”科技攻关项目。仪器在测试精度、测试速度及具有打印输出等总体技术性能方面超过了英国同类产品水平,已在路面评价管理系统中广泛应用,效果良好,深受用户欢迎。研制单位根据三年来各地的使用经验,最近对仪器的传感器作了重大改进,以光电编码器取代了过去仿英产品用的超越离合器,用链条取代钢丝绳传送位移量等,大大的提高了仪器的使用质量,扩大了仪器对平整度的测量范围,对于一些有严重破损(如坑洼、拥包)的等外待修路面也可进行测量。仪器结构更为合理,不仅测试速度快,而且由于取消了易损件钢丝绳大大减少了使用保养的工作量。
Car bump accumulator is a rapid determination of road surface roughness equipment, is the national “Seventh Five-Year” scientific and technological projects. The instrument surpasses the level of similar products in the United Kingdom in terms of test accuracy, test speed, and printout. It has been widely used in pavement evaluation management system and has been well received by users. Based on the experience of the past three years, the development unit made major improvements to the sensor of the instrument recently. The photoelectric encoder replaces the overrunning clutch used in imitation of British products, the displacement of the wire rope by a chain, etc., greatly improving the The use of quality, expanding the instrument on the flatness of the measurement range, for some serious damage (such as potholes, kits) waiting for pavement can be measured. Instrument structure is more reasonable, not only test speed, but also because of the elimination of consumable wire rope greatly reduce the workload of maintenance.
