Abstract

The invention discloses a stiffness adjustment device of a double-coupling air spring. The stiffness adjustment device of the double-coupling air spring comprises a bellows-type frame, a first air spring and a second air spring which are arranged in the bellows-type frame in series, a middle cross beam arranged between the two air springs, air inflation and deflation mechanisms and a power input mechanism; and air inflation and deflation are conducted on the first air spring and the second air spring through the air inflation and deflation mechanisms to change the stiffness of the double-coupling air spring. Monitoring of air pressure inside the air spring is conducted through air pressure sensors, the air inflation and deflation mechanisms are controlled to conduct the air inflation and deflation on the air springs to adjust the pressure of air inside the first air spring and the second air spring, and therefore the stiffness adjustment of the two air springs is achieved; and according to the stiffness adjustment device, the structure is compact, use is convenient, when the external environment and a power vibration exciting source change, the stiffness adjustment of the springs of a double-coupling mechanism can be achieved without replacing the springs, the use range of the double-coupling spring mechanism is enlarged, and the adaptability is improved.

Description

technical field [0001] The invention relates to the technical field of designing air springs, in particular to a double-coupled air spring stiffness adjustment device. Background technique [0002] Because the double coupling spring mechanism uses springs for flexible loading, it can avoid the impact of the load during the excitation and reversing process of the vibration excitation device of the test system, and its structural size is compact, so it is often used in the vibration loading mechanism of the test system. At present, rigid springs are used in double-coupled spring mechanisms. When the applied vibration load changes, the springs must be replaced and reassembled, resulting in a waste of time. Frequent disassembly also has a serious impact on the performance of the springs. At the same time, the mechanical loss of the rigid coil spring is large, and it is not easy to recover after the spring stiffness is changed. [0003] The air spring is a spring that is filled ...
