Dynamics
动力学研究物体的运动与受力之间的关系,是理论力学的核心内容之一。课程内容包括质点运动学、刚体运动学、质点动力学、刚体动力学、动能定理、动量定理、达朗贝尔原理以及振动基础。学生将学习运用牛顿第二定律、拉格朗日方程等方法分析机械系统的运动规律,为机械设计、机器人学和振动分析等后续课程提供理论支撑。
Dynamics studies the relationship between motion and forces, a core part of theoretical mechanics. Topics include kinematics and kinetics of particles and rigid bodies, work-energy principles, impulse-momentum methods, d'Alembert's principle, and vibration fundamentals. Students analyze mechanical system motion using Newton's laws and Lagrange's equations, providing theoretical support for machine design, robotics, and vibration analysis.
学生需对给定参数的曲柄滑块机构进行完整动力学分析,包括运动学分析(位移、速度、加速度)、受力分析(含惯性力)、平衡分析及飞轮设计计算。要求建立机构运动方程,绘制运动线图,并讨论机构参数对动力学性能的影响。最终提交分析报告及MATLAB仿真结果。
Students perform complete dynamic analysis of a slider-crank mechanism, including kinematic analysis (displacement, velocity, acceleration), force analysis with inertial forces, balancing, and flywheel design. Establish motion equations, plot kinematic curves, and discuss the influence of parameters. Submit a report with MATLAB simulation results.
