机械毕业论文范文大全(篇十一)1为何如此重视人机工程学在煤矿机械的作用

中国是产煤大国，因资源丰富所以矿山机械产品也很多，煤矿机械属于野外施工中的重型机械，设备不仅庞大，而且操作复杂，而且面临的问题也很多，例如：噪音、油污、振动等干扰因素多，并且天气的复杂多变也影响操作员的正常工作，因此长时间操作是非常困难的，操作员一直不停地操作会因疲劳无法提高生产效率。现在人们对煤机设备的设计即希望造型新颖、布局合理、线条优美等有着审美价值，又希望操作过程中疲劳和精神负担，提高工作效率，减少事故发生。人机工程学作为这些年来新兴的一门学科。它涵盖的综合性较强，例如：人体科学、安全科学、环境科学、工程技术科学、社会科学及技术美学等各种方面理论的知识、研究方法和手段,运行到整个体统中去,把人的生理、心理特征整合到机械中区，让人与环境与机电设备三者这件的关系相互贯通,这样操作简便、安全舒适、让人、机、环境的结合达到最佳状态。

2人机工程学在煤矿机械设计中的作用

人体数据在机械设计中的应用

人性化设计的机械界面

这里所指的操作界面主要是指人机界面的页面。人机界面是人与机器之间传递和交换信息的媒介，是人与机器之间的界面交流。我们所知煤矿设备由于机械较庞大所以结构复杂、零部件机构较多,所以操作界面很是复杂和繁琐。界面杂乱无序会让你眼花缭乱，操作起来使人烦躁,还有种很粗糙的感觉,并且存在严重的安全隐患。我们所希望的人机界面，在外形上要美观大方,操作上要通俗易懂、操作便利，而且要有引导功能,让操作员在工作的过程中感觉到快乐,从而提高工作效率。操作面板是人与机器相交的主要界面,人在面板上进行运行操作,操作起其位置和倾斜角度达到人的需求，对界面上的显示、控制装置的大小、位置等，都要适应的人的舒适度，这样在操作时可以便捷、正确和高效的工作状态。

减少煤矿机械操作中的噪音

煤炭工业是多噪声行业,这种噪声不止存在在一个环节中，而是在各个生产环节中都存在的，所以对人的危害是很大的。煤矿生产设备噪声的生源繁多而且音量很高。这种噪声长时间下来对人耳可造成听力损失；这种噪声已经严重到影响技术员的正常工作，还造成人的睡眠质量下降，严重的还会引起各种疾病的发生；音量太大，技术员在工作中无法专注，会引起一系列的工作上的失误，对于较大负荷的强度工作，如果因为噪声的原因，引起的后果将是不可想象的；不仅如此，因为噪声还会让仪器设备无法正常运转,造成仪表读数不准、失灵，甚至还可能金属材料因声疲劳而破坏。因此，设计人员在煤矿机械设备设计的时候就要考虑到噪声的因素，我们要减少因噪声带来的影响。例如在设计时，设计人员了解煤矿通风机和局部通风机是噪声最大的发源地，我们就要减少这些部件的噪声，在通风机选型、空气动力学设计与机械设计时，保证通风机工作时噪声较低，或是把通风机的尺寸变大或是缩小，设计的这些原理，前提是不能影响技术经济的指标下，方可达到减低噪声的效果。

3结束语

现代化的机械工程在设计中会考虑人机工程学原理，已达到人性化的设计。结合环境因素、人为因素在设计中的影响。保证技术人员在工作操作中者可以放心安全的工作，还能保证提高工作效率。机械设计是非常重要的环节，因此设计产品时要充分考虑到人为的因素才可以解决劳动主体与劳动工具之间的矛盾，但也因现在人的能力是有限的，设计的有些产品无法适应人的操作，这样就不可能达到期望的人机协调。随着
