Principle of finite element analysis: the function v may be a dependent variable in a partial differential equation (i.e., temperature, torque, vibration, pressure, etc.). The function v can be approximated as a new function v h by a linear combination of basis functions according to the following expression:
and u is uh 
And here psi i represents these basis functions and υ i represents the coefficients in the υ h function used to approximate υ. Fig. 11 illustrates this principle in a one-dimensional problem.
For example, υ may represent the temperature of a certain uniformly heated rod at a certain length (x). The values of the linear basis functions in fig. 10 are 1 at the respective nodes and 0 at the other nodes. In this example, the x-axis portion (i.e., the length of the shaft) in which the domain of the function resides has seven elements in total.
The function υ (a solid line) is approximated by υ h (another solid line), which is a linear combination of linear basis functions (denoted by ψ i, the third solid line). The coefficients of the linear basis functions are represented by v 0 to v 7.
One of the benefits of using the finite element method is that it provides great freedom in the choice of dispersion (including both the choice of dispersion for the elements of the discrete space and the discrete basis functions). For example, in FIG. 10, the cells are evenly distributed on the x-axis (although this is not always the case). In a region where the gradient of the function v is large, smaller cells may also be used, as shown below. The function υ (a solid line) is approximated by υ h (another solid line), which is a linear combination of linear basis functions (denoted by ψ i, the third solid line). The coefficients of the linear basis functions are represented by v 0 to v 7.
Each pulse acquisition unit is calculated through a finite element analysis chip, all the units are linearly projected on a two-dimensional space, and when the pulse function value in a certain time region exceeds the average function value, an alarm is triggered (as shown in fig. 10).
