Simulation of Output Amplitude Response of Electroacoustic Converting System in an Ultrasonic Plastic Welder Using the Finite Element Method

超声波塑料焊机电声转换系统输出振幅响应的有限元模拟

The amplitude-frequency response curves of the system are acquired.

通过对定常解平均方程的稳定性分析,得到了系统主参数共振解的幅频响应曲线.

It is concluded that the response of this system is a pitchfork bifurcation and the influence of excitation amplitude F 1, F 2 and damping μ is great. The property of the solutions can be easily controlled by adjusting F 1, F 2 and μ.

研究表明，该系统的稳态响应为一叉型分岔，激励幅值F1，F2和阻尼μ对普适开折参数的影响很大，通过调整F1，F2和μ可以很方便地控制解的分岔特性。

If the phase change, while the amplitude is almost constant, tidal water level response to meet the transition state.

若相位变化，而振幅几乎不变，井水位潮汐响应满足过渡状态。

This text offer a technique to generate totally non-stationary ground motion spectrum with non-stationary phase as the consideration of site conditions and earthquake environment and it is on the base of traditional technic which only take consideration of non-stationary amplitude to fit target response spectrum.

本文提出一种在传统的通过调整傅立叶幅值谱以拟合目标反映谱的基础上根据不同的场地条件和地震环境引入非平稳的相位来拟合目标反应谱。
