論文分析、計算結果表明， qtjs160t鐵路起重機底架結構滿足強度要求，論文給出了車架、支腿和銷軸聯接處的局部應力情況，指出車架在回轉支承圈處存在應力集中部位。 -
Taking the natural frequency arid the ratio of frequency drop as input characteristic parameters, crack damage in the cylindrical supporting shell of a portal crane is diagnosed and its length and position are forecasted, applying finite element emulation and artificial neural network technologies
摘要應用有限元模擬技術和人工神經網路模型，以反映結構損傷程度的固有頻率和損傷的頻率下降率作為神經網路輸入的特徵參數，對門座起重機筒形支柱上出現的裂紋損傷長度和位置進行了綜合診斷和預測分析。 -
During construction, special building methods were used to limit environmental damage, such as the piles being bored into the seabed rather than pile driven, to avoid mud sediment settling on the corals and killing them. most of the superstructure was prefabricated off - site, brought in by barge and then placed in position by crane to minimise the pollution, rubbish and noise
例如裝設支撐中心的樁柱時採用鉆挖形式，取代普通的打樁方式，務求減少翻起海床的沙泥，避免珊瑚窒息及死亡大部份上層建築組件是在建築地點以外的地方預先製作，並由駁船運到海下，再以吊車裝嵌，從而把施工帶來的污染垃圾及噪音減至最少。 -
All the major crane manufacturers have been devoted to solving these problems ; few ideal resolutions have been obtained yet. though. with the development of gps technology. some tentative new methods to deal with such problems are made possible. this paper probes into how to apply gps technology - global position system with the function of measuring time and distance by use of navigation satellites into integrated container rtp
各大製造廠長期以來致力於這些問題的研究，但效果似乎並不理想。 gps的誕生及技術性能的提高為輪胎吊這些問題解決提供了新的方法。 gps的含義是利用導航衛星進行測時和測距，以構成全球定位系統，本文就gps在集裝箱rtg上的應用進行探索和研究。 -
A new control method to use single chip controller and grating position sampling technology is put forward based on the control principle of crane hoisting limiter
摘要根據起重機的行程限位控制原理，提出了採用單片機作為控制主機，光柵作為位置采樣的新型控制方案，並就其硬體和軟體的設計做了較深入的闡述。 -
Anti - sway and position control of tower crane
塔式起重機吊裝物擺動的控制 -
Furthermore, because the three grades decelerate control method, which is used widely, in stack crane control in china has some shortcoming, two rbf neuron network applied in position error study and dot position control is put forward. because neuron network is of self - study, emendation and modification can be achieved in control and can remedy the shortcoming caused by shortage of sample
另外，本文還針對目前國內在對堆垛機控制方面普遍採用的三段式減速控制規律的弊病，提出用兩個rbf神經網路分別作為位置誤差學習器和點位位置控制器，由於神經網路的自學習功能，可以使得在控制當中不斷校正和修改在訓練時由於樣本不足造成的缺憾。 -
For the sake of the meet the market demand, the time wasted in the aspects of designing lowers, designing the efficiency higher - is an inevitable require that visitations heavy design developing whole crane design, the dam in crane occupies the very important position, it is the foundation of the crane design in this paper, we summarized developing status of computer aided design and monumental design method made a comparatively systematic study of computer aided design, and approach computer aided design from different angles
為了滿足市場需求，在設計方面耗費的時間降低，設計效率高是起重設計發展的必然要求。在整個起重機設計中，起重機小車占據極其重要的地位，它是起重機設計的基礎。本文首先綜述了計算機輔助設計的發展狀況和基本設計方法，比較系統地研究、探討了計算機輔助設計技術。
