With the increase of labor cost and mining difficulty of mineral resources, large-scale mining excavators are more and more widely used. With the deepening of the research, the large-scale mining excavator has made great progress in external perance and technology. In comparison, the man-machine problem in the cab is more and more prominent. As the drivers main operating space, the man-machine layout, interior decoration, interface and other aspects of the cab man-machine design level will have an important impact on the drivers comfort, operating efficiency, safety. Therefore, the application of ergonomics has important practical significance for the design of mining cab for large mines. Based on the theory of ergonomics and taking the WK-35 mining excavator of Taiyuan Heavy Machinery Group Co., Ltd. as the research object, this study proposed a design scheme of cab suitable for mining excavators.By means of experiment and computer simulation, the operating area of the existing large mining excavator was deeply analyzed, and man-machine system problems such as the positioning of the operating device, the design of the console interface and the modeling of the cab were studied, so as to provide a more comfortable and more reasonable working environment for the driver. The main research work and results of this paper are as follows 1 A control device layout based on motion capture technology was proposed. The motion capture experiment was designed to study the positioning of the controlling device by using the wearable 3D motion capture system and the subjective comfortability questionnaire based on semantic differential SD . By testing the angle and subjective comfort of the upper limb joint of the subjects, the comfort area of the control handle was obtained, and the joint comfort gradient table of the excavator driver was established. 2 A joystick design based on 3D coordinate measurement of key points was proposed. The shape of the joystick was studied and the shape of the grip area was determined by measuring the coordinates of key points in different 万方数据 太原理工大学硕士学位论文 IV percentile to which operators may grip. On this basis, the overall design of the joystick was completed, and the 3D model of the joystick was established by using the NURBS modeling . 3 Applying the interface layout principle of human-machine engineering and the design of vector controller interface into the interface design of large mining excavator, the interface design and positioning of the console were studied. The existing interface was optimized and the console was rearranged based on human vision theories, and the 3D model of the console was established. 4 A more suitable modeling for the large excavator based on the traditional purpose-oriented product modeling and semantic differential SD was proposed. This was used to study the modeling problems in the operational space of the WK-35s cab and to establish the design purpose of the cab of the large mining excavator. Based on the design of the control device and the console interface, the design of the operational space of the large excavators cab was completed, and the 3D model of the cab was established. 5 Based on Jack virtual simulation technology, this study uated the man-machine system of the excavator cab, including the visibility of the display panel and bucket, the accessibility of operators upper limbs and the comfortability. Through virtual simulation analyses before and after the improvement, the feasibility of the improving scheme was verified. The outcome of this study could provide some insights for the initial cab design in large mining excavators, and also help improve the domestic man-machine design capability of large mining excavators cab.
