【摘要】：隨著水路運(yùn)輸業(yè)的發(fā)展,船用客梯車(chē)成為各大港口不可缺少的專用車(chē)輛。汽車(chē)輕量化是現(xiàn)代汽車(chē)工業(yè)發(fā)展的方向,輕量化技術(shù)通過(guò)減小汽車(chē)質(zhì)量來(lái)降低油耗及排放,對(duì)節(jié)省能源與保護(hù)環(huán)境有重大意義。本課題以廣泰空港設(shè)備股份有限公司的GTK95C船用客梯為主要研究對(duì)象,對(duì)其上的車(chē)載式剪式升降機(jī)構(gòu)進(jìn)行結(jié)構(gòu)優(yōu)化和輕量化設(shè)計(jì),以減小客梯車(chē)整車(chē)整備質(zhì)量、降低油耗、改善排放、降低成本。本課題主要以船用客梯車(chē)上的升降機(jī)構(gòu)為研究對(duì)象,在三維建模軟件Pro/Engineer中建立升降機(jī)構(gòu)的三維模型,并將其導(dǎo)入多體動(dòng)力學(xué)分析軟件ADAMS中進(jìn)行結(jié)構(gòu)動(dòng)力學(xué)分析,進(jìn)行分析時(shí)根據(jù)升降機(jī)構(gòu)實(shí)際工作情況,分別對(duì)升降機(jī)構(gòu)的舉升工況和加載工況進(jìn)行仿真模擬,得到兩種不同工況下各約束副處的作用力值。并在ADAMS中建立升降機(jī)構(gòu)的參數(shù)化模型,對(duì)參數(shù)化模型進(jìn)行多體動(dòng)力學(xué)分析,同樣也需要分別對(duì)升降機(jī)構(gòu)的舉升工況和加載工況進(jìn)行仿真模擬,得到兩種不同工況下各約束副處的作用力值。隨后參照升降機(jī)構(gòu)實(shí)際模型在兩種工況下的各約束副處作用力值,檢驗(yàn)升降機(jī)構(gòu)參數(shù)化模型在兩種工況下的各約束副處作用力值,發(fā)現(xiàn)兩種模型仿真所得結(jié)果非常接近。故而,在后期的結(jié)構(gòu)優(yōu)化中可以不用實(shí)際模型,而采用升降機(jī)構(gòu)的參數(shù)化模型進(jìn)行優(yōu)化,從而簡(jiǎn)化優(yōu)化過(guò)程。利用ADAMS對(duì)升降機(jī)構(gòu)參數(shù)化模型進(jìn)行結(jié)構(gòu)優(yōu)化,根據(jù)優(yōu)化目標(biāo)可將優(yōu)化過(guò)程分為兩步進(jìn)行:首先,假設(shè)液壓缸安裝距在人為調(diào)節(jié)下始終能滿足要求,對(duì)升降機(jī)構(gòu)剪叉臂長(zhǎng)度進(jìn)行優(yōu)化,使升降機(jī)構(gòu)模型各剪叉臂的受力情況趨于最優(yōu)。通過(guò)優(yōu)化,升降機(jī)構(gòu)剪叉臂長(zhǎng)度由初始設(shè)計(jì)時(shí)的2550mm縮短為2320mm;然后,在第一步優(yōu)化的基礎(chǔ)上,對(duì)升降機(jī)構(gòu)液壓缸安裝位置進(jìn)行優(yōu)化,使升降機(jī)構(gòu)模型各剪叉臂的受力情況更為合理。對(duì)完成結(jié)構(gòu)優(yōu)化的剪式升降機(jī)構(gòu)各剪叉臂進(jìn)行ANSYS有限元分析,在滿足剪叉臂的剛度要求的前提下,對(duì)剪叉臂進(jìn)行尺寸優(yōu)化,通過(guò)縮小剪叉臂管型材的厚度實(shí)現(xiàn)升降機(jī)構(gòu)的輕量化目標(biāo),四個(gè)剪叉臂的總質(zhì)量明顯減小。
[Abstract]:With the development of waterway transportation, ship passenger ladder has become an indispensable special vehicle in various ports. Automobile lightweight is the direction of the development of modern automobile industry. Lightweight technology reduces fuel consumption and emissions by reducing vehicle quality. It is of great significance to save energy and protect the environment. The main research object of this paper is the GTK95C ship passenger ladder of Guang Tai Airport equipment Co., Ltd. The structure optimization and lightweight design of the on-board shearing mechanism are carried out in order to reduce the quality of the whole vehicle preparation, reduce the fuel consumption and improve the emission. To reduce the cost, this paper mainly takes the lifting mechanism of the passenger ladder car as the research object, and establishes the three-dimensional model of the lifting mechanism in the three-dimensional modeling software Pro/Engineer. And it is introduced into the multi-body dynamics analysis software ADAMS for structural dynamics analysis, according to the actual working situation of lifting mechanism. The lifting and loading conditions of the lifting mechanism are simulated respectively, and the force values of the two different conditions are obtained, and the parametric model of the lifting mechanism is established in ADAMS. In the multi-body dynamics analysis of the parameterized model, it is also necessary to simulate the lifting and loading conditions of the lifting mechanism separately. The force values of the two different working conditions are obtained, and then the actual model of the lifting mechanism is referred to the force values of the two kinds of working conditions. The test results of the parameterized model of lifting mechanism at each constraint side under two working conditions show that the simulation results of the two models are very close. Therefore, the actual model can be used in the later structural optimization. In order to simplify the optimization process, the parameterized model of the lifting mechanism is adopted to optimize the structure of the lifting mechanism. ADAMS is used to optimize the structure of the parameterized model of the lifting mechanism. According to the optimization objective, the optimization process can be divided into two steps: first, assuming that the installation distance of the hydraulic cylinder can always meet the requirements under artificial adjustment, the length of the shearing fork arm of the lifting mechanism is optimized. Through optimization, the length of shearing fork arm of lifting mechanism is shortened from 2550mm to 2320mm. Then, on the basis of the first step of optimization, the hydraulic cylinder installation position of lifting mechanism is optimized. The ANSYS finite element analysis of the shear fork arm of the structure optimization is carried out under the premise of satisfying the requirement of the stiffness of the shear fork arm. The dimension of the shearing arm is optimized and the light weight target of the lifting mechanism is realized by reducing the thickness of the shear-arm tube profile. The total mass of the four shearing arms is obviously reduced.
