什么是振动呢? 物体往复通过平衡位置,沿直线或曲线的运动过程称为振动,如钟摆在工作时就处于振动状态。振动又分为简谐振动、周期振动和随机振动。 简谐扳动 物体最简单的振动形式是简谐振动。简谐振动符合正弦运动规律,可由下式表示: 式中: X—瞬时位移; A—振幅(最大位移); What is vibration? Reciprocating object through the equilibrium position, along a straight line or curve of the movement process is called vibration, such as the pendulum in the work in a state of vibration. Vibration is divided into harmonic vibration, periodic vibration and random vibration. Simple harmonic vibration object is the simple harmonic vibration form. Harmonic vibration in line with the law of sinusoidal motion can be expressed by the following formula: Where: X-instantaneous displacement; A-amplitude (maximum displacement);
