Vibration absorbing mechanism for converting complex vibration into triaxial reciprocating vibration

Abstract

A vibration absorbing mechanism for converting complex vibration into triaxial reciprocating vibration comprises an upper panel, an upper frame, a lower frame, a lower panel, an elastic system and a damping system, wherein the elastic system comprises a transverse spring leaf set, a longitudinal spring leaf set, a spring and a vertical spring leaf set; the damping system comprises a vertical damping rod, a transverse damping rod and a longitudinal damping rod; the lower panel, the lower frame, the upper frame and the upper panel are distributed as four-staggered steps from bottom to top; the transverse spring leaf set, the longitudinal spring leaf set, the spring and the vertical spring leaf set which are used as elastic elements are mounted and connected among the steps to form the elastic system of the vibration absorbing mechanism; the vertical damping rod, the transverse damping rod and the longitudinal damping rod which are used as damping elements are mounted and connected among the steps to form the damping system of the vibration absorbing mechanism. According to the mechanism, the complex vibration at the bottom part is decomposed into reciprocating vibration in three directions, and the vibration energy in the three directions can be absorbed and consumed through the damping system, so that the irregular complex vibration can be converted into triaxial reciprocating vibration which can be averaged and reduced through an inertial navigation system mathematical algorithm, and as a result, a good vibration absorbing effect can be achieved.

Description

technical field [0001] The invention belongs to the field of anti-vibration and anti-shock technologies, and in particular relates to a shock-absorbing mechanism that transforms complex vibrations into triaxial reciprocating vibrations. Background technique [0002] Wheeled and tracked vehicles will produce various bumps, vibrations and even shocks due to the complex terrain during driving. If these vibration and shock loads are not protected, they will cause damage to the precision instruments on the vehicle. In order to reduce the impact and damage of these harmful loads on the precision instruments on the vehicle, an anti-shock and vibration damping device is usually installed between the vehicle-mounted inertial navigation and the installation base in the vehicle, or directly rely on the internal vibration reduction system of the inertial navigation to protect the interior of the inertial navigation inertial components. At present, high-quality rubber shock absorbers an...

Problems solved by technology

However, the performance of the above-mentioned external shock absorbers mainly depends on the products of rubber shock absorbers and spring shock absorbers themselves. It is inevitable that additional angular vibration or irregular self-excited oscillation will be generated during vibration reduction, which will affect the navigation accuracy of the inertial navigation system. At the same time, if the performance of a single rubber shock absorber or spring shock absorber on the external shock absorber is greatly changed or damaged, the navigation accuracy of the inertial navigation system will be further reduced, and even the inertial navigation device will be damaged.
