工程机械在工作状态时,驾驶员与整机构成了一个完整的人机系统,如何使人机系统的工作效率达到最大化是业内一直研究的课题,其中,环境因素是对其产生影响的主要因素之一。这里的环境通常包括外部工作环境和内部操控环境。一般来讲,我们很难控制或改变工程机械的外部工作环境,却可以从噪声和振动控制、温度环境、驾驶室空气质量、安全性等方面有效保证驾驶室内操控环境的舒适性。尤其是安全方面,既要考虑驾驶室内环境的安全性,也要考虑驾驶员在外环境中视线可及区域的布置。需要注意的是,鉴于成本压力、操作实用性等方面的考虑,部分机型的驾驶室采用了开放性设计。这种情况下,需要限制整机的工作场地,以保证驾驶员的人身安全。
Construction machinery in the working state, the driver and the machine constitutes a complete man-machine system, how to maximize the efficiency of man-machine system is the industry has been the subject of research, of which environmental factors are its main impact One of the factors. The environment here usually includes the external working environment and the internal control environment. In general, it is difficult to control or change the external working environment of the construction machinery, but it can effectively guarantee the comfort of the operating environment in the cab from noise and vibration control, temperature environment, cabin air quality and safety. Especially in terms of safety, it is necessary to consider the safety of the driving indoor environment as well as the layout of the driver’s sight in the outer environment. It should be noted that, in view of cost pressures, operational considerations, etc., some models of the cab adopted an open design. In this case, you need to limit the work area of the machine to ensure the driver’s personal safety.
