Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] Please refer to Figure 1 and Figure 2, an embodiment of the present invention provides a vibration control method, comprising:

[0034] Step S001 , according to the constraint conditions and the target conditions, a topology optimization design method is used to design the controlled structure to obtain a topology structure 101 with optimized structure-stiffness-damping distribution.

[0035] First, the constraints and target conditions of the controlled structure are determined as needed, wherein the constraints can be the response characteristics of the controlled structure, such as acceleration range, displacement speed range, etc., or weight range, size range, etc. Then, a topological structure 101 with the best structure-stiffness-damping distribution is obtained through a topological optimization design method, and the topological structure 101 can effectively suppress vibration and help improve the safety of equipment use.

[0036] Step S002 : performing vibration modal analysis on the topological structure 101 to obtain the installation position of the actuating device on the topological structure 101 .

[0037] The installation position of the actuator is optimally configured, so that the actuator can cooperate with the topological structure 101 to more effectively suppress vibration after installation, thereby further improving the safety of the equipment.

[0038] In this embodiment, the actuating device includes a vibration sensor 201, an actuator 202 and a controller 203. The vibration sensor 201 and the actuator 202 are respectively connected to the controller 203 for communication. The vibration sensor 201 and the actuator 202 are both used to connect with the topological structure 101. The vibration sensor 201 is used to sense the vibration data of the topological structure 101 and provide it to the controller 203. The controller 203 is used to control the operation of the actuator 202 according to the vibration data. The installation position includes a first installation position 102 and a second installation position 103. The vibration sensor 201 is used to be installed at the first installation position 102, and the actuator 202 is used to be installed at the second installation position 103. Therefore, after the vibration sensor 201 is installed at the first installation position 102 and the actuator 202 is installed at the second installation position 103, the controller 203 can control the actuator 202 to apply vibration to the second installation position 103 according to the vibration data of the first installation position 102, thereby more effectively suppressing the generation and transmission of vibration of the topological structure 101, and further improving the safety of equipment use.

[0043] Step S004 , forming a control strategy of the controller 203 according to the interaction data, and the controller 203 is used to control the operation of the actuator 202 according to the vibration data and the control strategy.

[0044] By analyzing the interaction data of the actuator when it is connected to the topological structure 101, the interaction mechanism between the actuator and the topological structure 101 can be understood, thereby forming a control strategy of the controller 203. After the vibration sensor 201 is installed at the first installation position 102 and the actuator 202 is installed at the second installation position 103, the controller 203 can control the actuator 202 to apply vibration to the second installation position 103 according to the vibration data of the first installation position 102 and the control strategy, thereby more effectively suppressing the generation and transmission of vibration of the topological structure 101, and further improving the safety of equipment use.

[0049] Step S006, comparing the vibration control effect data with the target condition, and outputting the comparison result.

[0050] Therefore, it can be understood whether the vibration control effect of the actuating device and the topological structure 101 in actual cooperation can meet the given requirements.

[0052] In this embodiment, the constraints and target conditions of the controlled structure are first determined as needed, wherein the constraints may be the response characteristics of the controlled structure, such as the acceleration range, displacement velocity range, etc., or may be the weight range, size range, etc. Then, the controlled structure is topologically optimized through the topological optimization design module 301 to obtain the topological structure 101 with the best structure-stiffness-damping distribution. The topological structure 101 can effectively suppress vibration and help improve the safety of equipment use. Then, the topological structure 101 is subjected to vibration modal analysis through the analysis module 302 to obtain the installation position of the actuator on the topological structure 101, and the installation position of the actuator is optimized. Thus, after installation, the actuator can cooperate with the topological structure 101 to more effectively suppress vibration, thereby further improving the safety of equipment use.

By analyzing the interaction data of the actuator device when it is connected to the topological structure 101, the interaction mechanism between the actuator device and the topological structure 101 can be understood, thereby forming a control strategy of the controller 203. After the vibration sensor 201 is installed at the first installation position 102 and the actuator 202 is installed at the second installation position 103, the controller 203 can control the actuator 202 to apply vibration to the second installation position 103 according to the vibration data of the first installation position 102 and the control strategy, thereby more effectively suppressing the generation and transmission of vibration of the topological structure 101, and further improving the safety of the use of the equipment.
