课程名称：完整的机械振动在线课程 RAHME301 Rahsoft 概述：机械振动是力学中最重要的应用之一。在机械振动领域，我们处理许多重要且实用的问题，找到这些问题的解决方案至关重要。在大多数情况下，针对振动系统的解决方案可以挽救许多人的生命。学习机械振动的前提课程包括静力学、动力学和材料力学。为了解决机械振动中的问题并更好地理解其应用，学生需要具备这些领域的扎实知识。机械振动的学生必须学习如何利用现有知识，根据适当的假设对机械系统进行建模。这些假设包括自由度的数量和著名的力学原理。学生将会熟悉推导 governing model 的方程，然后对其进行求解。有时模型结果的解决方案容易找到（少量的微分方程），而有时需要其他假设。 本课程的目的是为学习机械振动的学生提供指导，涵盖振动分析的多个方面。同时，本课程还旨在培养学生设计有效结构以减轻令人烦恼的振动的能力。在第一章中，您将熟悉机械振动的基本概念，并介绍用于建模振动系统的不同元素。在第二章和第三章中，考虑了振动系统中的两个一般情况：自由振动和谐振。在每一章中都有许多与现实世界问题直接相关的实际示例，我们使用这些示例进行更详细的说明。
Mechanical vibration is one of the most important application of Mechanics. In Mechanical vibration we deal with many important and practical problems that finding their solution is critical. In most cases, solutions for vibratory systems can save many human's lives.The prerequisites for studying mechanical vibration are courses such as statics, dynamics and mechanics of material. To solve problems in Mechanical vibration and better understanding of its application a solid knowledge of all these areas is needed.A student of mechanical vibrations must learn how to use the knowledge that exists to model a mechanical system with appropriate assumptions. Assumptions like number of degrees of freedom, famous mechanics principles. The student will get familiar with deriving the equations governing the model and then solve them. Sometimes the solution for modeling results are easy to find (a small group of differential equations) and sometimes some other assumptions are needed.The purpose of this course is to draw a guideline for students who study mechanical vibrations through many aspects of vibration analysis. Also the course is planned to give the student the ability to design useful structures for damping annoying vibrations.In First chapter you will get familiar with basic concepts in Mechanical vibrations and also different elements used in modeling vibratory systems are introduced. In second and third chapter two general cases in vibratory systems are considered, free and harmonic vibration. in each chapter there are many practical examples that are directly connected with problems in real world, we use these examples for more illustration.
