    摘要:

    車轍表面原始形貌數(shù)據(jù)對(duì)深入研究車輪與松散地面相互作用機(jī)理具有重要意義。為了快速準(zhǔn)確地獲得土槽試驗(yàn)中松散地面上車轍表面原始數(shù)據(jù)，設(shè)計(jì)了帶有二維移動(dòng)框架的激光掃描儀，該裝置的最大掃描面積是650mm×400mm，測(cè)距范圍為0.05~65m，掃描分辨率為0.1mm。在此基礎(chǔ)上設(shè)計(jì)出帶有一維移動(dòng)框架的激光掃描儀，以滿足月球車內(nèi)場(chǎng)試驗(yàn)中快速測(cè)量車轍表面形貌的要求。對(duì)土槽試驗(yàn)與月球車內(nèi)場(chǎng)試驗(yàn)中的車轍表面進(jìn)行測(cè)量，試驗(yàn)結(jié)果表明所設(shè)計(jì)的激光掃描儀能夠使用非接觸測(cè)量方法在不擾動(dòng)車轍的條件下獲得車轍表面形貌的縱向斷面圖和三維圖形。

    Abstract:

    The rut geometric analysis is necessary for studying the interaction between the driving wheel and the loose soil. A laser scanner that consisted of a laser sensor and a 2-D traversing frame was developed to measure the digit parameters of ruts in the soil bin which were produced by the rigid wheel on loose soil. The maximum scanning area was 650mm×400mm, measurement range was 0.05～65m and scanning resolution was 0.1mm. A laser scanner with 1-D traversing frame which might be more appropriate for the measurements of rut deformation in the infield of rover was also discussed. The experimental results showed that the scanners could obtain the sections and the 3-D graphics of the surface of ruts by using contactless measuring method without disturbing the ruts. 
