【摘要】：隨著社會經(jīng)濟的發(fā)展和人民生活水平的提高，兒童入學(xué)率逐年提高，從而帶動了兒童上下學(xué)的運輸市場逐漸興起和擴大。然而，不斷發(fā)生的各種校車行駛安全事故，反復(fù)刺痛著人們敏感的神經(jīng)，引發(fā)了全社會對校車安全的關(guān)注和討論。因此，開展校車的安全性評價系統(tǒng)研究，，對提高校車的綜合安全性能，減少校車安全行車事故的發(fā)生具有重要意義。同時，也為學(xué)校或校車運營企業(yè)選擇校車車型提供一定參考依據(jù)。 目前國內(nèi)外常用的汽車安全性評價方法主要是碰撞試驗和碰撞仿真試驗。盡管試驗可以給出汽車被動安全性較為準確地評價結(jié)果，但由于未考慮影響車輛安全性能的主動安全性因素，其評價結(jié)果缺乏全面性�，F(xiàn)有的汽車安全性仿真評價模型是以轎車為基礎(chǔ)建立的，由于轎車和校車在結(jié)構(gòu)上存在明顯差異，因此并不適用于校車安全性評價。 本文在研究分析校車安全性影響因素基礎(chǔ)上，以校車安全性評價試驗規(guī)范要求和仿真試驗方法為參考，使用目標(biāo)分解法對評價指標(biāo)進行初選、篩選和優(yōu)化，建立了校車安全性評價指標(biāo)體系。校車安全性評價指標(biāo)包括定量指標(biāo)和定性指標(biāo)兩類。根據(jù)評價指標(biāo)不同的數(shù)據(jù)分布特征，選擇合適的標(biāo)準化方式對其進行標(biāo)準化處理。然后運用相對比較法計算出校車安全性評價體系指標(biāo)權(quán)重，確定各評價指標(biāo)對校車安全性影響的不同程度。進而建立基于模糊綜合評價的校車安全性評價模型。論文最后以兩款已投放使用的校車安全性對比為工程實例，驗證了校車安全性評價模型的科學(xué)性、準確性、可行性和實用性。
[Abstract]:With the development of social economy and the improvement of people's living standard, the school enrolment rate of children is increasing year by year, which leads to the rising and expanding of the transportation market of children to and from school. However, various kinds of school bus safety accidents repeatedly prick people's sensitive nerves and cause the whole society to pay attention and discuss the school bus safety. Therefore, the research of school bus safety evaluation system is of great significance to improve the comprehensive safety performance of school bus and reduce the occurrence of school bus safety accidents. At the same time, it also provides some reference for school or school bus operation enterprises to choose school bus models. At present, the commonly used vehicle safety evaluation methods are collision test and collision simulation test. Although the test results can give a more accurate evaluation of the passive safety of the vehicle, the evaluation results are not comprehensive because the active safety factors affecting the safety performance of the vehicle are not taken into account. The existing vehicle safety simulation evaluation model is based on the car, because there are obvious differences in the structure between the car and the school bus, so it is not suitable for the school bus safety evaluation. Based on the research and analysis of the influencing factors of school bus safety, this paper uses the goal decomposition method to select, select and optimize the evaluation index, taking the requirements of school bus safety evaluation test standard and simulation test method as the reference. The evaluation index system of school bus safety is established. School bus safety evaluation index includes quantitative index and qualitative index. According to the different data distribution characteristics of the evaluation index, the appropriate standardization method is selected to standardize it. Then the relative comparison method is used to calculate the index weight of school bus safety evaluation system and determine the different degree of influence of each evaluation index on school bus safety. Then the safety evaluation model of school bus based on fuzzy comprehensive evaluation is established. At the end of this paper, the safety comparison of two school buses has been taken as an engineering example to verify the scientific, accurate, feasibility and practicability of the safety evaluation model of the school bus.
