自動(dòng)液壓車轍試驗(yàn)成型機(jī)基本原理和結(jié)構(gòu)：

瀝青混合料的車轍試驗(yàn)是試件在特定的溫度和荷載條件下，測(cè)定試驗(yàn)輪往返行走所形成的車轍變形速率，以每產(chǎn)生1mm變形的行走次數(shù)（即動(dòng)穩(wěn)定度）表示。本車轍試驗(yàn)儀采用試件固定，試驗(yàn)輪運(yùn)動(dòng)的方法。試件被固定在恒溫槽(空間)，試驗(yàn)輪在減速電機(jī)和曲軸連桿的拖動(dòng)下，以每分鐘21次的速率來(lái)回往返。如圖所示：試驗(yàn)輪以及荷重被安裝在光杠導(dǎo)軌上，被來(lái)回拖動(dòng)。試驗(yàn)輪碾壓試件，產(chǎn)生形變，位移傳感器檢測(cè)到微小的變形，這些變形數(shù)據(jù)及其試驗(yàn)輪運(yùn)動(dòng)次數(shù)數(shù)據(jù)被傳輸給計(jì)算機(jī)，經(jīng)過(guò)運(yùn)算后，顯示成變形曲線。

試驗(yàn)輪負(fù)重(壓強(qiáng))出廠已經(jīng)調(diào)整到0.7Mpa。根據(jù)試驗(yàn)要求，荷重可以被調(diào)整。一個(gè)三相電動(dòng)機(jī)被減速器調(diào)整為每分鐘21轉(zhuǎn)，拖動(dòng)試驗(yàn)輪每分鐘往返21次。

The basic principle and structure of the automatic rutting test machine:
The rutting test of the asphalt mixture is to determine the deformation rate of the rut formed by the test wheel moving back and forth under specific temperature and load conditions, and is expressed by the number of walking (ie, dynamic stability) per 1 mm deformation. The rutting tester uses a test piece to fix the test wheel movement method. The test piece was fixed in a constant temperature bath (space), and the test wheel was reciprocated back and forth at a rate of 21 times per minute under the drag of the geared motor and the crankshaft link. As shown in the figure: The test wheel and the load are mounted on the light bar guide and are dragged back and forth. The test wheel crushes the test piece to generate deformation, and the displacement sensor detects minute deformation. The deformation data and the data of the number of times of the test wheel movement are transmitted to the computer, and after the operation, the deformation curve is displayed.
The load weight (pressure) of the test wheel has been adjusted to 0.7Mpa. The load can be adjusted according to the test requirements. A three-phase motor was adjusted to 21 rpm by the reducer, and the test wheel was dragged 21 times per minute.
