【摘要】：工程机械驾驶室是工程机械的重要组成部分，特别是在野外艰苦环境下施工的工程机械，对其驾驶室进行人性化设计尤为重要。本论文利用人机工程学理论，对工程机械驾驶室的安全性和舒适性进行了理论研究和设计实践，并应用多层次模糊理论对设计结果进行了设计评估。本论文的主要研究工作如下： 1.详细叙述了工程机械驾驶室的分类和构成，分析研究了工程机械驾驶室构成部分的设计要点和设计原则，在此基础上提出了工程机械驾驶室的设计评估流程。 2.以工程机械中凿岩机的驾驶室为例，对凿岩机驾驶室骨架进行了结构设计，并根据FOPS/ROPS理论，利用ANSYS对骨架进行有限元仿真,完成对骨架的安全性设计与校核。 3.在满足安全性设计的基础上，，进行驾驶室的舒适性设计，应用坐姿作业、视野、以用户为中心等人机工程学理论，对驾驶室的舱体、座椅等部件进行布局设计和校核，并对驾驶室总体进行了减震降噪处理，使得驾驶室设计更符合人体舒适性需求。 4.应用多层次分析法及模糊理论对凿岩机驾驶室的设计结果进行了舒适性评估，从理论上来验证凿岩机驾驶室的设计结果。本论文将结构设计、安全设计理论、以用户为中心的人机工学理论、心理学、减震降噪理论融合，对以凿岩机驾驶室为代表的工程机械驾驶室进行了综合设计。在工程机械的人性化设计方面做了一些有益的尝试。
[Abstract]:The cab of construction machinery is an important part of construction machinery, especially the construction machinery under the difficult environment in the field, so it is very important to design the cab humanized. Based on the ergonomics theory, the safety and comfort of the cab of construction machinery are studied and designed in this paper, and the design results are evaluated by using the multi-level fuzzy theory. The main work of this thesis is as follows: 1. The classification and composition of the cab of construction machinery are described in detail, and the design essentials and design principles of the cab of construction machinery are analyzed and studied. On the basis of this, the flow of design and evaluation of the cab of construction machinery is put forward. 2. Taking the cab of rock drill in construction machinery as an example, the structural design of the cab skeleton of rock drill is carried out. According to FOPS/ROPS theory, finite element simulation of the skeleton is carried out by using ANSYS, and the safety design and verification of the skeleton are completed. On the basis of satisfying the safety design, the comfort design of the cab is carried out. By applying the ergonomics theory, such as sitting posture, visual field, and taking the user as the center, the layout design and checking of the cabin, seat and other components are carried out. And the overall cab vibration noise reduction treatment, so that the cab design more in line with the human comfort requirements. 4. The design results of drilling cab are evaluated by using multi-level analysis method and fuzzy theory, and the design results of drilling cab are verified theoretically. In this paper, the structural design, safety design theory, user-centered theory of human mechanics, psychology, shock absorption and noise reduction theory are combined to design the cab of construction machinery, which is represented by rock drill cab. Some useful attempts have been made in humanized design of construction machinery.
