ADCP流速仪检定拖车驱动方案探讨

Discussion on driving scheme of ADCP current meter verification trailer

近年ADCP流速仪在国内应用不断增多，急需建设可以检定ADCP流速仪的检测平台规范水利行业产品应用。ADCP流速仪检定水槽的长、宽、深等尺寸设计，必须根据ADCP流速仪产品特点进行专门设计。相比以往检定水槽，ADCP水槽的宽度增加很多，相对应的检定拖车的跨度也会增加很多，导致检定拖车的车重增加很多，而大型检定拖车的驱动设计方案是系统设计成败的关键。根据ADCP流速仪检测特点，该文提出基于交流伺服同步电机的ADCP流速仪检定拖车混合动力驱动（4马区／2驱）设计方案：高速段（0．2～6m／s）采用四轮驱动，低速段（0．01-0．2m／s）采用2轮驱动，很好地解决工作速度段大跨度下速度准确度控制难题，满足ADCP流速仪不同速度段检定需求。

In recent years, application urgent need to build a testing platform of ADCP current meter in China has been increasing, so it is in capable of testing ADCP current meter to regulate the application of products in the water industry. Length, width, depth and other dimensions of verification tank must be specially designed in accordance with the features of Compared to the previous verification tanks, ADCP tank is obviously wider, co ADCP current meter ADCP current meter. rrespondingly, span of corresponding verification trailer will also increase, which will inevitably lead to increase of weight of the verification trailer, while driver design scheme of large verification trailer is the key for success of the system. According to the testing features of ADCP current meter, NZS design group puts forward a design scheme of ADCP current meter verification trailer hybrid drive （4 WD/2 WD） based on AC synchronous servo motor： 4 - wheel drive is adopted in the high - speed segment （0.2 - 6m/s） and low 2 - wheel drive is adopted in the low- speed segment （0.01 -0.2m/s）,so that problem that it is difficult to control speed accuracy at large span in the operating speed segment is solved well, and the verification requirements of ADCP current meter at different speed segments are met.
