Sentence examples for modal frequency was from inspiring English sources

Physical properties such as Young's modulus and section inertias were chosen as the input features and modal frequency was the only response feature.

Then, the modal frequency is reduced to lower frequencies (20,100 and 200 Hz).

The structural optimization shows that the mass of the side plate is decreased by 194.50kg, the second and third modal frequency is increased by 1.73% and 2.91% respectively and a better optimal effect is received.

The method involves screening out non-relevant assembly parameters using IV-optimal designs and the preload of the joints is chosen as the input features and modal frequency is the only response feature.

More specifically, the maximum fundamental modal frequency is limited to about 2 MHz in immersion by the process design rule, and the maximum output pressure is restricted by a maximum driving voltage of 25Vpp because of potential dielectric breakdown of the piezoelectirc layer.

The results show satisfactory accuracy, as the overlap ratio index of each modal frequency is over 89% without the average absolute value of relative errors, and the CDF of normal distribution has a good coincidence with measured frequencies of Guanhe Bridge.

A novel concept of combining the mode shape ratios with the modal frequencies was recently introduced to develop an accurate method for the determination of stay cable force.

As a result, mode and modal frequencies are obtained from mathematical expressions.

For wind turbines, a further complication is that the modal frequencies are dependent on the turbine rotation speed.

An appreciable decrease in the modal frequencies is observed when fluid structure interaction is taken into account.

Using only damping ratios judged to be reliable, the variation of damping with modal frequencies is studied for all buildings.
