【摘要】：目前国家大力发展第三产业,过山车由于其刺激性与娱乐性,受到广大年轻人的喜爱,国内各大主题游乐园和小型室内游乐场在全国各地发展迅速,然而国内游艺设备公司的设计水平良莠不齐,设计方法在安全性与创新性方面仍存在不足,在此大背景下,根据国家对特种设备设计的要求规范,本文利用三维设计方法和仿真分析进行设计,以提高产品设计效率和该产品的安全性等设计质量。根据三环室内过山车车体的设计目标,本文进行了该车车体的总体方案设计,利用Solid Works软件对三环过山车车体进行三维结构设计,包括首车、中间车、尾车、轮桥装配、中间连接器和尾部连接器。按照室内布局初步设定了轨迹点,将轨迹点导入软件ADAMS中,生成样条曲线,然后将三环过山车的车体零部件导入软件ADAMS中,添加约束及载荷,对三环过山车进行了运动学仿真,经仿真后处理,得出相关数据,对这些数据进行分析,经过对轨迹和车体反复修改,满足了G加速度国标规范要求。在完成三环过山车的车体整体结构设计后,确定三环过山车的轨道轨迹,设计出来的轨道既要满足过山车运行过程中对速度、加速度和关键件受力的要求,又不能使过山车在运行过程中车体与轨道有干涉现象。采用仿真软件ADAMS提取关键件受力,再用ANSYS软件对三环过山车的轮组、立轴、中间连接器和尾部连接器等关键件进行强度校核与有限元分析,若不满足要求,则需要反复修改重新进行上述设计,直到满足设计要求。通过对轨道的半径与车体结构进行修改,得出的仿真结果表明该三环过山车可以在室内稳定的运行,轨道全长为355m,运行一周时间约为66.71S,最大速度低于80Km/h,安全系数达到5,满足设备设计要求,本文的研究方法和研究成果可给同类产品的设计作为参考。
[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.
