锤击激励 meaning in Chinese
impact excitation
Examples
- Under these assumptions , three kinds of excitations , namely , harmonic force with frequency equal to the structural fundamental frequency , harmonic force with frequency equal to half of the structural fundamental frequency and pulse force are inputted to the undamaged and damaged structures . then under the same excitation , the undamaged structural displacement responses , velocity responses , acceleration responses , jerk responses and responses of integrated displacement are compared with that of the damaged ones
在此假定基础上,分别将激励频率等于结构基频的简谐形激励、激励频率等于结构基频之半的简谐形激励和锤击激励输入结构,而后比较了损伤前后结构在相同激励下的位移响应、速度响应、加速度响应、加加速度响应和位移积分响应。 - Three kinds of excitations , namely , harmonic force with frequency equal to the structural fundamental frequency , harmonic force with frequency equal to half of the structural fundamental frequency and pulse force are applied to such four kinds of models . the displacement responses of the four kinds of models are calculated using sap2000 and the integrations of displacement responses are obtained by numerical calculations
将三种激励形式:激励频率等于结构基频的简谐形激励、激励频率等于结构基频之半的简谐形激励和锤击激励分别施加在这四种模型上,通过计算得到四种模型的位移响应,进而得到位移积分响应。 - The outputs of tests on the thin plate under different inputs have been investigated for testifying the system . different solutions have been compared according to the frequency - spectrum characters and structure modal parameters . it is indicated that the solutions in this paper are consistent with the solution of the fea methods
