【摘要】：目前國家大力發(fā)展第三產(chǎn)業(yè),過山車由于其刺激性與娛樂性,受到廣大年輕人的喜愛,國內(nèi)各大主題游樂園和小型室內(nèi)游樂場(chǎng)在全國各地發(fā)展迅速,然而國內(nèi)游藝設(shè)備公司的設(shè)計(jì)水平良莠不齊,設(shè)計(jì)方法在安全性與創(chuàng)新性方面仍存在不足,在此大背景下,根據(jù)國家對(duì)特種設(shè)備設(shè)計(jì)的要求規(guī)范,本文利用三維設(shè)計(jì)方法和仿真分析進(jìn)行設(shè)計(jì),以提高產(chǎn)品設(shè)計(jì)效率和該產(chǎn)品的安全性等設(shè)計(jì)質(zhì)量。根據(jù)三環(huán)室內(nèi)過山車車體的設(shè)計(jì)目標(biāo),本文進(jìn)行了該車車體的總體方案設(shè)計(jì),利用Solid Works軟件對(duì)三環(huán)過山車車體進(jìn)行三維結(jié)構(gòu)設(shè)計(jì),包括首車、中間車、尾車、輪橋裝配、中間連接器和尾部連接器。按照室內(nèi)布局初步設(shè)定了軌跡點(diǎn),將軌跡點(diǎn)導(dǎo)入軟件ADAMS中,生成樣條曲線,然后將三環(huán)過山車的車體零部件導(dǎo)入軟件ADAMS中,添加約束及載荷,對(duì)三環(huán)過山車進(jìn)行了運(yùn)動(dòng)學(xué)仿真,經(jīng)仿真后處理,得出相關(guān)數(shù)據(jù),對(duì)這些數(shù)據(jù)進(jìn)行分析,經(jīng)過對(duì)軌跡和車體反復(fù)修改,滿足了G加速度國標(biāo)規(guī)范要求。在完成三環(huán)過山車的車體整體結(jié)構(gòu)設(shè)計(jì)后,確定三環(huán)過山車的軌道軌跡,設(shè)計(jì)出來的軌道既要滿足過山車運(yùn)行過程中對(duì)速度、加速度和關(guān)鍵件受力的要求,又不能使過山車在運(yùn)行過程中車體與軌道有干涉現(xiàn)象。采用仿真軟件ADAMS提取關(guān)鍵件受力,再用ANSYS軟件對(duì)三環(huán)過山車的輪組、立軸、中間連接器和尾部連接器等關(guān)鍵件進(jìn)行強(qiáng)度校核與有限元分析,若不滿足要求,則需要反復(fù)修改重新進(jìn)行上述設(shè)計(jì),直到滿足設(shè)計(jì)要求。通過對(duì)軌道的半徑與車體結(jié)構(gòu)進(jìn)行修改,得出的仿真結(jié)果表明該三環(huán)過山車可以在室內(nèi)穩(wěn)定的運(yùn)行,軌道全長為355m,運(yùn)行一周時(shí)間約為66.71S,最大速度低于80Km/h,安全系數(shù)達(dá)到5,滿足設(shè)備設(shè)計(jì)要求,本文的研究方法和研究成果可給同類產(chǎn)品的設(shè)計(jì)作為參考。
[Abstract]:At present, the country is vigorously developing the tertiary industry, and the roller coaster, because of its stimulating and entertaining nature, is loved by the broad masses of young people. Domestic major theme amusement parks and small indoor playgrounds are developing rapidly throughout the country. However, the design level of domestic entertainment equipment companies is mixed, and the design methods are still insufficient in terms of safety and innovation. Under this background, according to the requirements of the state for the design of special equipment, In this paper, 3D design method and simulation analysis are used to improve the design efficiency and safety of the product. According to the design goal of the three-ring indoor roller coaster body, the overall scheme of the car body is designed in this paper, and the three-dimension structure design of the three-ring roller coaster body is carried out by using Solid Works software, including the assembly of the front car, the middle car, the rear car and the wheel bridge. Intermediate connector and tail connector. According to the indoor layout, the trajectory points are preliminarily set, and the trajectory points are introduced into the software ADAMS to generate the spline curve. Then, the body parts of the three-ring roller coaster are imported into the software ADAMS, and the constraints and loads are added to simulate the kinematics of the three-ring roller coaster. After the simulation, the relevant data are obtained and analyzed. After repeated modification of the track and the car body, the requirements of the GB standard for G acceleration are met. After the overall structure design of the three-ring roller coaster has been completed, the track of the three-ring roller coaster is determined. The designed track must meet the requirements of the roller coaster for speed, acceleration and the force of the key parts during the operation of the roller coaster. Also can not make roller coaster in the operation of the car body and track interference phenomenon. Using the simulation software ADAMS to extract the force of the key parts, and then using the ANSYS software to check the strength and finite element analysis of the key parts of the three-ring roller coaster, such as wheel group, vertical shaft, middle connector and tail connector, if the requirements are not satisfied. The design needs to be modified again and again until the design requirements are met. By modifying the radius of the track and the structure of the car body, the simulation results show that the three-ring roller coaster can run steadily indoors. The track has a total length of 355m, the running time is about 66.71S, and the maximum speed is less than 80km / h. The safety factor is up to 5, which meets the requirements of equipment design. The research method and research results in this paper can be used as reference for the design of similar products.
