【摘要】：機動車輛已成為許多大城市的首要污染源,如何解決由于機動車過快發(fā)展帶來的環(huán)境污染和道路擁堵問題是我國面臨的重要課題之一�？焖俟籅RT對于解決我國環(huán)境污染、交通擁堵問題有著非常重要的推動作用�？焖俟籅RT因其具有運量大、專用車道、站外售票和道路優(yōu)先權等特點迅速獲得各大城市青睞而得以快速推廣。實踐證明,城市快速公交BRT系統(tǒng)是解決大城市公共交通問題的有效途徑。然而,城市公共設施的供電問題一直為人們所詬病,尋找一種可以保障城市公共設施安全、穩(wěn)定的供電途徑已成為各專家學者的主要研究目標之一。利用快速公交BRT專用道進行道路能量采集并將采集到的能量用作公交站臺用電設施的備用電源和附近交通設施的電源供給,為解決用電設施的供電問題提供了一種新型的綠色節(jié)能發(fā)電技術。本文圍繞快速公交BRT道路能量采集關鍵技術展開研究,提出了一種基于城市快速公交BRT的棋盤式道路能量采集系統(tǒng)。本文的主要研究工作如下：首先,提出一種新型的棋盤式道路能量采集系統(tǒng)設計方案。本文提出的道路能量采集系統(tǒng),采用模塊化設計,包括棋盤式能量輸入模塊、能量傳輸模塊、微型發(fā)電機模塊和能量存儲模塊,并將所有模塊封裝在一個箱體中,可以實現(xiàn)快速安裝與更換。并且此系統(tǒng)無凸出地面的部分,解決了傳統(tǒng)道路能量采集裝置因凸出地面而對駕駛員行車心理產(chǎn)生干擾的問題。通過三個交替嚙合的錐齒輪實現(xiàn)了將雙向旋轉運動轉化為單向旋轉運動,大幅提高能量采集效率。其次,棋盤式道路能量采集系統(tǒng)建模與仿真。建立微型發(fā)電機的動力學模型,引入鍵結圖中“勢”和“流”的概念成功解決了涉及機械和電氣的多領域耦合仿真的問題。通過理論計算得到每輛車經(jīng)過本文設計的棋盤式道路能量采集裝置后可以采集到的能量,為分析系統(tǒng)發(fā)電量提供理論支撐。采用Solidworks Motion和Multisim對系統(tǒng)進行了軟件環(huán)境下的仿真研究,結果表明本系統(tǒng)的能量采集效率最高可以達到62.38%。機構分析結果顯示了能量采集機構的結構設計安全性。最后,棋盤式道路能量采集裝置的平臺搭建及優(yōu)化。在實驗平臺的加工過程中,根據(jù)現(xiàn)場實際對道路能量采集裝置的機構提出一些改進措施。改進之處主要包括三個方面：①大錐齒輪的加工方式；②棘爪的固定方式及配合方案；③發(fā)電機的支撐方案。通過這些改進措施降低了機構的復雜度,減小了加工工藝的難度,提高了裝置運行穩(wěn)定性,簡化了組裝程序并節(jié)約了加工成本。此外,本文還介紹了西南交通大學和深圳綠車道有限公司合作研發(fā)的電磁式道路能量采集裝置。和棋盤式道路能量采集系統(tǒng)不同,此能量采集裝置需依附于減速帶。在對其進行仿真研究之后,為驗證其實際道路能量采集效果,又對其進行了道路測試,測試結果顯示此道路能量采集裝置的瞬時峰值電壓可以達到194.0V。最后,對其能量輸入機構進行了改進以降低成本和工程難度。
[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.
