【摘要】：為了解決有軌起重機(jī)在轉(zhuǎn)彎時(shí),出現(xiàn)的啃軌問(wèn)題。提出先修正內(nèi)側(cè)軌道再修正外側(cè)軌道的方法。對(duì)于內(nèi)側(cè)軌道,在直線(xiàn)段和圓弧段軌道加入一段緩和曲線(xiàn),使曲率半徑從無(wú)窮大逐漸過(guò)渡到圓弧曲率半徑;對(duì)于外側(cè)軌道,通過(guò)四角門(mén)框計(jì)算出外側(cè)兩角點(diǎn)的軌跡。通過(guò)求兩角點(diǎn)軌跡的中線(xiàn),即四角門(mén)框的外側(cè)軌道,再疊加多輪修正值δ進(jìn)一步修正外側(cè)軌道。應(yīng)用Adams進(jìn)行動(dòng)態(tài)仿真,驗(yàn)證修正軌道是否可以安全通過(guò),并用Adams仿真優(yōu)化起重機(jī)基距、平衡梁尺寸。結(jié)果表明,加入的回旋線(xiàn)長(zhǎng)度Ls越大,有軌起重機(jī)大車(chē)在轉(zhuǎn)彎時(shí),出現(xiàn)的偏移量越小。同時(shí),得出有軌起重機(jī)平衡梁和基距最優(yōu)解。
[Abstract]:In order to solve the problem of gnawing the rail when the rail crane turns, the method of correcting the inner track and then the outer track is put forward. For the inner track, a relaxation curve is added to the line and arc track. The curvature radius is gradually transferred from infinity to arc curvature radius; for the outer orbit, the trajectory of the outer two corners is calculated by the quadrangular door frame, and the outer orbit of the quadrangular door frame is obtained by finding the central line of the trajectory of the two corners, that is, the outer orbit of the quadrangular door frame. The lateral track is further modified by superposition of multi-wheel correction value 未. The dynamic simulation with Adams is carried out to verify whether the modified track can pass safely. The base distance of crane is optimized by Adams simulation and the size of the balance beam is optimized. The results show that, The greater the raceway length of the rail crane is, the smaller the deviation will be. At the same time, the optimal solution of the equilibrium beam and the base distance of the rail crane can be obtained.
