1. The vibration states of the foundation of the hammering block and concrete have been simulated in different excitation conditions, different spring stiffness and damping conditions.
为了减少振动对周围环境的影响，目前工业中常采用主动隔振来消减振动，即采用各种弹性支承的方法来减少振动和噪声。
2. The solution of the model has been given using RKF (Runge-Kutta-Felhberg) algorithm which has high precision and high numerical stability. The vibration states of the foundation of the hammering block and concrete have been simulated in different excitation conditions, different spring stiffness and damping conditions.
采用高精度及高数值稳定性的RKF (Runge—Kutta—Felhberg)算法对模型进行了求解；对不同激励条件、不同弹簧刚度和阻尼条件下砧座及混凝土基础的振动情况进行了仿真；讨论了弹簧刚度、阻尼器阻尼系数和混凝土质量等参数对隔振效果的影响。
3. A heavy block of iron or steel with a smooth, flat top on which metals are shaped by hammering.
铁砧顶端平整光滑用来锤锻金属成型的厚重的钢块或铁块现在大部分是匀整的半翻着的燥裂的泥块。
