Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation examples.
[0036] figure 1 Shown is a structural block diagram of the multi-dimensional random vibration test control device of the present invention. The display interaction module ① and the calculation control module ② are composed of PC or industrial computer, and the computer plays the role of the upper computer in the test control device. The display interaction module ① mainly provides human-computer interaction interface and data curve display function, and the calculation control module ② includes the multi-dimensional random vibration test control algorithm based on matrix power operation according to the present invention. These two modules are developed by software and controlled by computer. Control software integration is realized.
[0037] The signal acquisition and processing module ③ and the signal output module ④ are compose...
