MATLAB-STM32 hybrid power test system and test method thereof

Abstract

The invention discloses an MATLAB-STM32 hybrid power test system which comprises an MATLAB numerical calculation unit, a data communication module, an STM32 embedded control module, a data acquisition module and a test unit, wherein the STM32 embedded control module comprises an STM32 embedded controller and a servo motor. The invention further discloses a test method of the MATLAB-STM32 hybrid power test system. An MATLAB (matrix laboratory) is creatively combined with the STM32 embedded controller, and the advantages of rich and flexible configuration, low power consumption, easiness in control and high control precision of the STM32 embedded controller are taken. Real-time bidirectional communication between the MATLAB and the STM32 embedded controller is realized, a numerical simulation test of an engineering structure MATLAB numerical calculation unit and a real object test of a test unit are cooperatively performed, and the problems of singleness, high cost, too high hybrid power test system manufacturing cost and application field limitation of an electro-hydraulic servo actuator of a traditional hybrid test system are solved.

Description

technical field [0001] The invention belongs to the field of experimental mechanics, and in particular relates to a novel hybrid power test system and a test method thereof which combine computer numerical simulation tests with physical physical tests. Background technique [0002] In the field of experimental mechanics, the test methods mainly used for some engineering structures include pseudo-static test, pseudo-dynamic test and shaking table test. The pseudo-static test applies a predefined displacement to the specimen through the actuator, so as to obtain the basic information of the specimen, such as stiffness, bearing capacity, deformation and energy dissipation capacity. This method is easy to operate and the results are easy to compare and analyze, but this method cannot reflect the change of the reaction force of the specimen caused by the strain rate, so this method cannot be used to study the performance of velocity or even acceleration-related components. The p...
