Abstract

The invention relates to a combined loading system for static strength tests of solid motors. The combined loading system is characterized by comprising a hydraulic energy part and a control part, wherein the hydraulic energy part comprises a plunger pump, a motor, an oil way block, an energy accumulator, a filter, a proportional overflow valve, a proportional reducing valve, a reversing valve, acooler and an actuating cylinder; and the control part comprises an alternating current motor, a force sensor, a communication interface, a digital quantity output driving circuit, an analog quantityoutput driving circuit and a central processing unit (CPU). The combined loading system for the static strength tests of the solid motors is suitable for the static strength tests of various solid motors, and solves the technical problems that the coordination control accuracy is low, safety factors of the tests are not considered fully and the like in the traditional hydraulic loading system.

Description

technical field [0001] The invention relates to a combined loading system for a static strength test of a solid engine, which belongs to the technical field of solid engine tests and is used for the mechanical strength test of a solid engine. Background technique [0002] Static strength test technology is a subject that observes and studies the strength, stiffness, stability, stress and deformation distribution of structures or components under static loads by means of tests. The static strength test of the solid engine is a test to observe and study the stress state of the parts and components of the solid engine structure by reproducing the load and boundary conditions through the test device under the laboratory conditions. The static strength test of the solid engine is not only an important means to verify the rationality of the structural form and the correctness of the structural static analysis, but also provides structural characteristic parameters for the establis...
