海運(yùn)甲板重大件設(shè)備剛性系固方案校核研究

發(fā)布時(shí)間:2018-08-14 17:48
【摘要】:近年來(lái),重大件運(yùn)輸已成為遠(yuǎn)洋運(yùn)輸市場(chǎng)中的重要組成部分。重大件設(shè)備通常都具有超高、超長(zhǎng)、超重的特點(diǎn),積載在船舶甲板上,多采用剛性系固方式。目前國(guó)內(nèi)外針對(duì)重大件剛性系固校核評(píng)判沒(méi)有明確的、有效的規(guī)范。由此,重大件設(shè)備運(yùn)輸過(guò)程中因重大件設(shè)備系固原因引起的事故時(shí)有發(fā)生,造成了生命和財(cái)產(chǎn)損失。因此,建立為之有效的剛性系固方案校核評(píng)判規(guī)范,確保系固方案的安全性,已成為一個(gè)重要課題。本文從甲板重大件設(shè)備的種類及其剛性系固設(shè)備入手,研究重大件所受外力的計(jì)算方法,分析基于直接計(jì)算法的剛性系固校核方法。結(jié)合有限元思想,提出了基于ANSYS的重大件設(shè)備剛性系固方案校核方法。本文采用基于ANSYS的重大件剛性系固方案校核方法對(duì)某一工程實(shí)例剛性系固方案進(jìn)行校核,分別對(duì)裝船機(jī)設(shè)備、系固設(shè)備和局部船體的結(jié)構(gòu)強(qiáng)度進(jìn)行校核。校核結(jié)果顯示:螺旋鋼管和插板的連接處出現(xiàn)了應(yīng)力集中,應(yīng)力值接近螺旋鋼管材料的許用應(yīng)力值,建議在螺旋鋼管和插板的連接處設(shè)置應(yīng)力釋放孔;裝船機(jī)設(shè)備、系固設(shè)備和局部船體的強(qiáng)度均滿足要求。該校核結(jié)果表明該剛性系固方案是安全有效的,與使用直接計(jì)算校核方法所得結(jié)果相同;贏NSYS的重大件剛性系固方案校核方法輸出的應(yīng)力結(jié)果直觀、可靠,能精確地找到系統(tǒng)結(jié)構(gòu)強(qiáng)度的薄弱區(qū)域,由此改良其剛性系固方案,具有實(shí)際應(yīng)用價(jià)值。本論文的研究成果對(duì)重大件設(shè)備剛性系固方案的校核評(píng)判具有一定的指導(dǎo)意義,為國(guó)內(nèi)研究重大件海上安全運(yùn)輸提供了技術(shù)支持。
[Abstract]:In recent years, the transportation of major parts has become an important part of ocean transportation market. Heavy equipment is usually super-high, super-long, overweight, stowage on the ship deck, most of the rigid fastening mode. At present, there is no clear and effective criterion for the evaluation of rigid fastening and checking of major parts at home and abroad. As a result, accidents caused by the fastening of major pieces of equipment occur from time to time, resulting in loss of life and property. Therefore, it has become an important subject to establish an effective criterion for the verification and evaluation of rigid fastening schemes and to ensure the safety of the fastening schemes. Starting with the types of deck heavy equipment and its rigid fastening equipment, this paper studies the calculation method of the external force of the heavy parts, and analyzes the method of rigid fastening and checking based on the direct calculation method. Based on the idea of finite element method, a method of checking the rigid fastening scheme of heavy parts equipment based on ANSYS is proposed. In this paper, the method of checking the rigid fastening scheme of major parts based on ANSYS is used to check the rigidity fastening scheme of a certain engineering example, and the structural strength of the loading equipment, the fastening equipment and the partial hull are checked respectively. The checking results show that the stress concentration appears at the joint of spiral steel pipe and socket plate, and the stress value is close to the allowable stress value of spiral steel pipe material. It is suggested that the stress release hole should be set at the joint of spiral steel pipe and socket plate, and the equipment of loading machine should be installed. Both the fastening equipment and the strength of the partial hull meet the requirements. The results show that the rigid fastening scheme is safe and effective, and the results are the same as those obtained by the direct calculation method. The stress output from the checking method of the rigid fastening scheme for major parts based on ANSYS is intuitionistic, reliable, and can accurately find the weak area of the structural strength of the system. Therefore, it is of practical value to improve the rigid fastening scheme of the system. The research results of this paper have a certain guiding significance for the verification and evaluation of the rigid fastening scheme of major parts equipment, and provide technical support for the domestic research on the maritime safety transportation of major parts.
