|Title:||STRAIN SENSOR OPTIMIZATION ARRANGEMENT METHOD BASED ON VIRTUAL TEST|
In the technical field of dynamics tests, provided is a strain sensor optimization arrangement method based on a virtual test, comprising: a step of representing, by using a Delta function, whether there is a strain sensor; a step of performing transient response analysis during the random movement of an applied impact load acting point; and a step of obtaining an optimal arrangement scheme for the strain sensor using a genetic optimization algorithm by taking the minimization of the total number of sensors and the maximization of a 2-norm of the sum of strain of impact responses as optimization targets. The beneficial effects of the method are that: a Delta function is used to characterize whether there is a strain sensor, wherein same is practical; based on a genetic algorithm, an impact load acting point can randomly move between skinning nodes, so that a strain sensor optimization arrangement result is universal; an optimization target is simple and easy to define and describe; and compared with traditional sensors, at least half of the sensors can be saved on in terms of arrangement number.
