Space explosion explosive shock test multiple parameters

Calculate the increase | lIIL1 speed, and then a secondary integral treatment of 0, that is, s = ÷ mouth, and second is the pressure from the measured data processing curves of the displacement curve obtained in Figure 4 for a round in which the data were tested products are after treatment compared with the measured displacement curve, we can see two curves are basically the same, with a small ripple in the curve of the measured curve. Can also be directly measured acceleration curve for the second integral handle, the same acceleration curve can be obtained from the measured displacement data processing curves obtained in this article data from the two measured curves obtained processing the graphics the same. (Continued on page 20) * 20 * new technologies and new equipment in 2009 Vol 29 No. 3 Table 1, the angle of the angle signal simulator output signal and measured values from Table 1 in the test data can be seen, the measurement results more accurate, measurement error in the range of ± 7, l2-bit resolution is consistent with the 12XSZ/ZSZ resolver digital converter module output angle error should be less than ± 8.5 of the design requirements. Using the resolver digital converter module design point of signal measurement in a certain type of aircraft attitude and heading reference system of regular inspection and troubleshooting work requirements played an important role. Application shows that: The point of the angle signal measurement device measuring accuracy, high reliability, small volume, light weight, flexible and convenient.

(Continued from page 16) Figure 4 from the measured pressure curve obtained by data processing with the measured displacement of the displacement curves of Figure 5 Conclusions special device designed, in a trial can be explosive at the same time after the structure of the displacement response parameters, acceleration parameters and the source of the pressure generated this response a total of three parameters, derived among each other, consistent with the theoretical calculation. Test results can be seen from the choice of sensor performance and stability,[link widoczny dla zalogowanych], a special bomb design, reasonable structure,[link widoczny dla zalogowanych], function normally, to replace the current and end by the closed bomb test bench to complete the test functions, respectively, in line with the output parameters of explosive testing requirements , to achieve more space explosive impact test parameters.
