【摘要】：机动车辆已成为许多大城市的首要污染源,如何解决由于机动车过快发展带来的环境污染和道路拥堵问题是我国面临的重要课题之一。快速公交BRT对于解决我国环境污染、交通拥堵问题有着非常重要的推动作用。快速公交BRT因其具有运量大、专用车道、站外售票和道路优先权等特点迅速获得各大城市青睐而得以快速推广。实践证明,城市快速公交BRT系统是解决大城市公共交通问题的有效途径。然而,城市公共设施的供电问题一直为人们所诟病,寻找一种可以保障城市公共设施安全、稳定的供电途径已成为各专家学者的主要研究目标之一。利用快速公交BRT专用道进行道路能量采集并将采集到的能量用作公交站台用电设施的备用电源和附近交通设施的电源供给,为解决用电设施的供电问题提供了一种新型的绿色节能发电技术。本文围绕快速公交BRT道路能量采集关键技术展开研究,提出了一种基于城市快速公交BRT的棋盘式道路能量采集系统。本文的主要研究工作如下：首先,提出一种新型的棋盘式道路能量采集系统设计方案。本文提出的道路能量采集系统,采用模块化设计,包括棋盘式能量输入模块、能量传输模块、微型发电机模块和能量存储模块,并将所有模块封装在一个箱体中,可以实现快速安装与更换。并且此系统无凸出地面的部分,解决了传统道路能量采集装置因凸出地面而对驾驶员行车心理产生干扰的问题。通过三个交替啮合的锥齿轮实现了将双向旋转运动转化为单向旋转运动,大幅提高能量采集效率。其次,棋盘式道路能量采集系统建模与仿真。建立微型发电机的动力学模型,引入键结图中“势”和“流”的概念成功解决了涉及机械和电气的多领域耦合仿真的问题。通过理论计算得到每辆车经过本文设计的棋盘式道路能量采集装置后可以采集到的能量,为分析系统发电量提供理论支撑。采用Solidworks Motion和Multisim对系统进行了软件环境下的仿真研究,结果表明本系统的能量采集效率最高可以达到62.38%。机构分析结果显示了能量采集机构的结构设计安全性。最后,棋盘式道路能量采集装置的平台搭建及优化。在实验平台的加工过程中,根据现场实际对道路能量采集装置的机构提出一些改进措施。改进之处主要包括三个方面：①大锥齿轮的加工方式；②棘爪的固定方式及配合方案；③发电机的支撑方案。通过这些改进措施降低了机构的复杂度,减小了加工工艺的难度,提高了装置运行稳定性,简化了组装程序并节约了加工成本。此外,本文还介绍了西南交通大学和深圳绿车道有限公司合作研发的电磁式道路能量采集装置。和棋盘式道路能量采集系统不同,此能量采集装置需依附于减速带。在对其进行仿真研究之后,为验证其实际道路能量采集效果,又对其进行了道路测试,测试结果显示此道路能量采集装置的瞬时峰值电压可以达到194.0V。最后,对其能量输入机构进行了改进以降低成本和工程难度。
[Abstract]:Motor vehicle has become the primary source of pollution in many large cities. How to solve the problem of environmental pollution and road congestion caused by the rapid development of motor vehicles is one of the important issues facing China. The rapid transit BRT has a very important role in promoting the problem of environmental pollution and traffic congestion in our country. The bus rapid transit BRT has a great effect on the problem of traffic congestion. Large volume, special lane, ticket and road priority and other characteristics quickly get the favor of the big cities and quickly popularize. Practice has proved that the urban rapid transit BRT system is an effective way to solve the problem of public transportation in big cities. However, the power supply problem of urban public facilities has been criticized by people, looking for a kind of guarantee city. The safe and stable way of power supply for public facilities has become one of the main research targets of the experts and scholars. Using the BRT special channel of bus rapid transit to collect the energy of the road and supply the energy used as the standby power supply of the bus station and the power supply of the nearby traffic facilities to provide the power supply for the power supply facilities. A new green energy saving power generation technology is introduced. This paper focuses on the key technology of BRT road energy acquisition, and puts forward a chessboard road energy acquisition system based on Urban BRT BRT. The main research work of this paper is as follows: first, a new type of chessboard road energy acquisition system is proposed. The road energy acquisition system, which is proposed in this paper, uses modular design, including chessboard energy input module, energy transmission module, micro generator module and energy storage module, and encapsulates all modules in a box, which can be quickly installed and replaced. And the system does not protrude the ground part and solves the traditional path. The problem that the road energy acquisition device interferes with the driver's driving psychology because of the protruding ground. Through three alternately meshed bevel gears, the bidirectional rotation motion is transformed into one direction rotation motion, and the energy acquisition efficiency is greatly improved. Secondly, the model and Simulation of the chessboard road energy acquisition system are established and the dynamics of the micro generator are established. The model, introducing the concept of "potential" and "flow" in the bond graph, successfully solved the problem of multi field coupling simulation involving mechanical and electrical. Through theoretical calculation, the energy collected by each car after the design of the chessboard road energy acquisition device is obtained, which provides theoretical support for the analysis of the power generation capacity of the system. The use of Solidworks Motion and Multisim have carried out simulation research on the system in software environment. The results show that the energy acquisition efficiency of the system is highest and the result of 62.38%. mechanism analysis shows the structural design security of the energy acquisition mechanism. Finally, the flat platform and optimization of the chessboard road energy acquisition device are built and optimized. Some improvement measures are put forward to the mechanism of the road energy collection device according to the actual situation. The improvement mainly includes three aspects: 1. The processing mode of the big bevel gear, the fixed mode and the matching scheme of the pawl, and the supporting scheme of the generator. The difficulty of the device improves the stability of the device, simplifies the assembly program and saves the processing cost. In addition, this paper also introduces the electromagnetic road energy acquisition device, which is developed by Southwest Jiao Tong University and Shenzhen Green Lane Co., Ltd., which is different from the chessboard road energy acquisition system. After the simulation study, in order to verify the actual road energy acquisition effect, the road test is carried out. The test results show that the instantaneous peak voltage of the road energy acquisition device can reach 194.0V., and the energy input mechanism is improved to reduce the cost and the difficulty of the engineering.
