7.- 力学

力学是一门科学学科,负责研究影响自然界中存在的元素的物理现象。尽管它被称为力学,但它实际上涵盖了古典力学和量子力学,这是现代物理学的两个基本支柱。

古典力学研究刚体以及具有有限或无限数量(连续介质)自由度的系统,而量子力学则研究小型或低能系统。

如同任何实验科学一样,对人体的任何机械研究都涉及从物理和数学的角度进行分析和实验的过程。但是,与其他科学学科不同,在力学中,研究在实际系统中解释的理论行为并不那么复杂。

得益于牛顿,拉格朗日,汉密尔顿或薛定er等众多科学家的贡献,可以建立一些力学的基本原理或定律:

  • 牛顿定律。
  • 保持动量原理。
  • 节约能源的原则。
  • 角动量守恒原理和旋转动力学基本方程。

考虑到他们的研究领域,最值得一提的是:

  • 工程。
  • 静态的。
  • 动态。
  • 流体力学。
  • 热力学和热传递。
  • 科学,材料的弹性和抵抗力。
  • 数值分析(有限元方法)。

由于该行业的不断发展,机械工程,汽车和汽车工程,结构计算,机械开发以及它们的安装和维护等分支是当前正在经历最大发展的领域。

7.1.- 机械工业

机械工程是将物理学应用于我们周围的元素,以改进现有的机械设备或创造新的设备。由于它是以物理原理为基础的,所以它的起源可以追溯到物理原理的起源,它的发展与力学的进步密切相关。然而,直到蒸汽机的发明,它才成为工业发展的支柱之一。由于这个装置的产生,17世纪的工业革命发生了。从那一刻起,随着瓦特、史蒂芬森、特斯拉或兰金等地位的科学家和工程师的贡献,无论是在理念上还是在新机器的研发上,都开始了前所未有的更新。随着这些机器的发展,人们对工业的概念发生了改变。大规模生产的引入,机器设计的改进,以及随之而来的生产工艺范围的扩大,催生了迄今为止难以想象的适应社会需求的各种新产品。在机械工程中,应特别提及...

7.2.- 汽车机械工程

汽车工业是当今机械工程的主要应用领域之一。使用汽油内燃机的汽车被认为是20世纪最伟大的发明,尽管第一辆原型车在18世纪末就开始制造。第一辆原型车可以追溯到1769年,由一辆蒸汽驱动的马车组成。虽然没有成功,但为1860年汽油机的发展开创了先河。从这一发现开始,就开始了不可阻挡的发展,奔驰、标致、菲亚特或福特等汽车工业如雨后春笋般涌现。在千年之交,开始研究使用其他化石燃料,如柴油。今天,利用现有的所有技术和手段,可以了解构成车辆的所有元素在无限多情况下的行为。之所以能达到这样的水平,得益于每个设计、分析等背后的工程。研究最多的一些系统是:传送。刹车。暂停。发动机性能。电子产品。排放。安全性...

7.3.- 材料工程

材料工程是负责材料科学工业解释的科学工业分支。人类学上,根据制造工具的材料(石器时代、青铜时代等),对人类发展的不同阶段进行了分类。因此,人类的发展与新材料的研究密切相关。在过去的200年里,关于材料的发现就像吉布斯的贡献一样具有启示性,它证明了材料的特性与其结构之间存在着关系。这些都使得石墨烯等新材料的开发和纳米材料或纳米技术等新领域的研究成为可能。为了达到这样的发展水平,必须进行无数次的试验,既有屈曲、硬度(洛氏、布氏、维氏、马顿斯)、扭转、牵引力(韧性和回弹力)、拉力(蠕变)、剪切力等机械试验,也有化学试验(热处理、内部结构等)。还可以对材料进行以下分类:金属(黑色和有色金属);瓷...
