**机械动力学课程总结** 本课程《机械动力学》在工业和日常家电领域扮演着至关重要的角色。课程核心在于研究运动中的机械系统。当系统处于动态运动状态时，惯性力随之产生，这是引起振动的根源。此外，重量或材料分布不均也会导致系统失衡，进而产生振动。 通过本课程的学习，学生将深入理解**平衡**的原理及其各种**平衡方法**，熟悉**机械振动**的基本概念。课程将涵盖**单自由度和双自由度系统**的自由无阻尼振动，以及自由阻尼和强迫阻尼系统。学成后，学生将能够根据系统要素**分类和识别**不同类型的平衡与振动。 此外，课程还将讲解**振动与噪声的测量技术**，为理解**机器的运行状态监测**提供关键参数知识。课程结束后，学生将掌握**平衡与振动**相关的实用技能，并能在实际应用中灵活运用。 **先修课程：** 材料力学、工程力学、工程数学与数值方法。
Dynamics of Machinery plays a very vital role in industry and the daily used appliances. Dynamics of Machinery deals with the study of machines or system when they are in motion. When there is motion of dynamic condition it leads to introduction of inertia forces in the system which is the cause of Vibrations. Also non uniform distribution of weights or non homogeneous distribution of material leads to genaration of unbalance in the system. This unbalance again generates the vibration in the system.Hence, studying this course will expose students to the principles of balancing and balancing machines. The course also describes the fundamental concepts in mechanical vibrations for the systems like - free undamped vibration for single degree and two degree of freedom systems, free damped and forced damped systems. Students will be able to classify and indentify the types of balancing and Vibrations based of elements in the system. Students will also learn the vibration and noise measurement techniques. This course will provide the knowledge of parameters to be considered for condition monitoring of machines. At the end of this course students would be in a position to apply the skills related to balancing and vibrations.Prerequisite: Strength of Materials, Engineering Mechanics, Engg. Mathematics and Numerical Methods
