[0056] like Figure 2 As shown, the surge converter includes: a charge amplifying unit, a filtering unit, a voltage amplifying unit and a voltage stabilizing unit.

[0057] In this embodiment, the pressure range is 0-500 N (Newton), the linear increasing rate is 10 N / second, the total test time is 50 seconds, and the pressure change curve is y=10x (x is time, unit: second).

[0058] In this embodiment, the discrete voltage vector is: V = [v1,…,v n ,…,v L ], the pressure vector is: S=[s1,…,s n ,…,s L ], v1 is the first voltage, v n is the nth voltage, v L is the Lth voltage, s1 is the first pressure, s n is the nth pressure, s L is the Lth pressure. The Hankel voltage matrix is: The Hankel pressure matrix is:

[0059] In the present invention, the length and width of the Hankel voltage matrix and the Kerr pressure matrix are the same.

[0060] In this embodiment, the development trend vector construction subsystem includes: a voltage deviation extraction module, a pressure deviation extraction module, a development trend value calculation module and a development trend vector construction module;

[0061] The voltage deviation extraction module is used to subtract each element in each row vector of the Hankel voltage matrix from the mean of the elements in the same row to obtain the voltage deviation value;

[0064] The development trend vector construction module is used to construct a development trend vector by taking the development trend value corresponding to each row as an element.

[0065] The present invention extracts voltage and pressure deviation values, accurately capturing deviation information from the signal and more accurately reflecting the performance changes of the impulse transducer under varying pressure conditions. By calculating the development trend of voltage and pressure deviation values within the same row number, the present invention can capture the performance trends of the impulse transducer during pressure changes.

[0066] In this embodiment, the formula of the development trend value calculation module is: Among them, ε i is the development trend value of the i-th row, v i,j is the voltage deviation value of the jth value in the i-th row, s i,j is the jth pressure deviation value in the i-th row, where i is the row number, j is a positive integer, and N is the number of voltage deviation values or pressure deviation values in a row.

[0067] In this embodiment, when the development trend value approaches 1, the voltage signal of the unit increases with the output of the accompanying piezoelectric sensor, and the two change in the same direction.

[0073] The present invention takes the ratio of pressure at adjacent moments and the ratio of voltage at adjacent moments to facilitate comparison of the overall ratio of pressure growth ratio to voltage growth ratio. The larger the growth trend value, the more sensitive the impact converter is to pressure changes and the better the performance of the impact converter.

[0076] The second-level element screening module is used to screen out elements less than or equal to 0.5 and greater than or equal to 0 in each development trend vector to obtain the second-level elements;

[0077] The third-level element screening module is used to screen out elements less than 0 in each development trend vector to obtain the third-level elements;

[0078] The development evaluation value calculation module is used to calculate the development evaluation value of the corresponding unit according to the first-level elements, the second-level elements and the third-level elements;

[0079] The adjustment module is used for obtaining the performance value of the impact converter based on the adjustment of the growth trend value according to the development evaluation value of each unit.

[0080] In this embodiment, the formula for the development evaluation value calculation module is: Among them, E is the development evaluation value, ζ 1,k is the kth first-level element, ζ 2,k is the kth second-level element, ζ 3,k is the kth third-level element, K1 is the number of first-level elements, K2 is the number of second-level elements, K3 is the number of third-level elements, and k is a positive integer.

[0081] By dividing the elements in the development trend vector into three levels (first level, second level and third level), the present invention can more finely distinguish the contribution of each element to the overall performance. Then, using the quantities K1, K2 and K3 as weights, the performance of the impact converter can be evaluated more accurately, ensuring that the evaluation results can truly reflect the actual contribution of each element.

[0083] The development evaluation value sequence construction submodule is used to arrange the development evaluation values of each unit according to the order of the units in the impact converter to obtain a development evaluation value sequence;

[0084] The growth trend value sequence construction submodule is used to arrange the growth trend values of each unit according to the order of the units in the impulse converter to obtain a growth trend value sequence;

[0086] The addition submodule is used to add all elements in the adjustment sequence to obtain the performance value of the impulse converter.

[0087] The present invention arranges the elements in the development evaluation value sequence and the growth trend value sequence according to the order of the units in the impact converter, so that when performing Hadamard product processing, the development evaluation value of the same unit is multiplied by the growth trend value of the same unit to obtain an adjustment value, and the adjustment values of all units are added together to obtain the performance value of the impact converter.

[0088] Example 2, a method for testing the dynamic performance of an impact converter, comprising the following steps:

[0089] S1, applying linearly increasing pressure to the piezoelectric sensor to collect the output voltage signals of each unit in the impact transducer;

[0090] S2. Sampling the output voltage signal of each unit at the same time interval to obtain a discrete voltage vector of each unit, and extracting the pressure at the corresponding sampling moment to construct a pressure vector;

[0093] S5. Calculate the growth trend value of each unit according to the discrete voltage vector and the pressure vector;

[0094] S6. Perform hierarchical processing on the elements in each development trend vector, calculate the development evaluation value of each unit, and calculate the performance value of the impact converter based on the adjustment of the growth trend value.

[0095] The specific implementation process of Example 2 is the same as that of Example 1.

[0096] This method applies linearly increasing pressure to the piezoelectric sensor to reveal the response characteristics of the impact transducer at different pressure levels. This linear increase allows for continuous dynamic changes in the impact transducer under different pressure states to be observed, avoiding transient response distortion that may be caused by sudden load changes.

[0097] The present invention samples the output voltage signal and pressure to obtain discrete voltage and pressure vectors, respectively. Hankel matrices are constructed for each discrete voltage and pressure vector, ensuring that each row and column of the matrix contains local information about the signal, thereby better reflecting the dynamic characteristics of the signal. By calculating the row vector trend values of the Hankel voltage and pressure matrices and constructing a trend vector, the performance trend of each unit under different pressures can be quantitatively evaluated, improving the accuracy of performance evaluation.

[0098] The present invention combines discrete voltage vectors and pressure vectors to calculate the growth trend value of each unit, reflecting the sensitivity of each unit's response, and then performs hierarchical processing on the elements in each development trend vector to calculate the development evaluation value of each unit. At the same time, combined with the adjustment of the growth trend value, it can more accurately reflect the performance of the impact converter at different pressure stages.

[0099] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
