【摘要】：电梯以其快捷方便的特性逐渐成为人们日常生活必不可少的工具。电梯由于其使用环境、功能、使用普遍等特殊性，一旦发生事故不但会导致人员伤害和财产损失，还会造成严重的社会影响，因此，研究电梯风险评价及控制具有十分重要的意义。本文从电梯系统使用寿命周期的全过程出发，结合电梯系统运行故障，建立电梯系统风险评价体系，借鉴模糊理论构建风险评价方法模型。文章所采取的方法及研究的内容如下：（1）电梯系统风险评价影响因素指标体系。从电梯设计、制造、安装、维保、改造/重大维修、使用、管理、检验等八个环节出发进行系统风险因素辨识，结合电梯使用实际特性构建事故可能性评价指标体系；从困人时间、社会影响、应急救援三方面出发构建事故后果严重程度评价指标体系。（2）电梯系统风险评价计算模型。对风险评价方法原理及适用性进行详细分析，在充分考虑电梯实际应用特征及故障运行情况的基础上，选用模糊变换计算建立基于故障率的电梯系统风险评价模型。在该模型基础上，提出科学的指标权重获取方法，建立合理的因素等级准则体系，完善正确的风险计算过程，得出有效的结果。（3）电梯系统风险评价实施过程及具体内容。在建立了完善的电梯系统风险评价方法模型后，，明确电梯系统评价详细的实施步骤及过程内容。主要包括信息资料收集，风险计算，构建风险矩阵判定风险等级，以ALARP原则判定控制措施，风险评价后续跟踪内容。（4）电梯系统风险评价软件。根据电梯系统风险评价方法模型，采用Microsoft C#语言进行电梯系统风险综合评价系统软件编制，完成风险评价因素管理、风险计算、结果处理等功能，快速得出准确结果。（5）工程实例应用。选取具有代表性和对比性的两台电梯，应用于已建立的电梯系统风险评价模型及软件系统，对评价得出的结果进行对比分析，同时与该电梯系统实际状况进行对比验证，分析本文风险评价模型及评价软件系统的有效性及工程应用效果。
[Abstract]:Elevator has gradually become an indispensable tool in people's daily life because of its quick and convenient characteristics. Because of the particularity of using environment, function and general use of elevator, once an accident occurs, it will not only cause injury and property loss, but also cause serious social impact. It is of great significance to study elevator risk assessment and control. Based on the whole process of the life cycle of elevator system and the running failure of elevator system, the risk evaluation system of elevator system is established in this paper, and the risk evaluation method model is constructed by using fuzzy theory as reference. The methods and contents of this paper are as follows: 1) the index system of influencing factors of elevator system risk evaluation. The system risk factors are identified from eight aspects of elevator design, manufacture, installation, maintenance, renovation / major maintenance, use, management and inspection, and the evaluation index system of the possibility of accident is constructed based on the actual characteristics of elevator. The evaluation index system of the severity of accident consequence is constructed from the aspects of time of trapped person, social impact and emergency rescue, and the evaluation model of elevator system risk is established. The principle and applicability of risk assessment method are analyzed in detail. On the basis of considering the actual application characteristics and fault operation of elevator, fuzzy transformation calculation is used to establish the risk evaluation model of elevator system based on failure rate. On the basis of this model, a scientific method of obtaining index weight is put forward, a reasonable criterion system of factor grade is established, a correct risk calculation process is perfected, and effective results are obtained. After establishing a perfect risk assessment model of elevator system, the detailed implementation steps and process contents of elevator system evaluation are clarified. It mainly includes collecting information, calculating risk, constructing risk matrix to judge risk grade, judging control measures based on ALARP principle, following up on risk evaluation. 4) elevator system risk evaluation software. According to the risk evaluation method model of elevator system, Microsoft C # language is used to compile the software of the elevator system risk comprehensive evaluation system. The functions of risk assessment factor management, risk calculation, result processing and so on are completed, such as risk assessment factor management, risk calculation, result processing and so on. Get the accurate result quickly. 5) the engineering example application. Two representative and comparative elevators are selected and applied to the established elevator system risk assessment model and software system. The results obtained from the evaluation are compared and verified with the actual situation of the elevator system. This paper analyzes the effectiveness of risk assessment model and evaluation software system and engineering application effect.
