Abstract

The invention discloses a vibration damping design method of a space pipeline in a strong vibration environment, including the following steps: step 1, establishing a bidirectional fluid-solid coupling simulation model of a space pipeline in a basic vibration; step 2, performing a orthogonal test design on the bidirectional fluid-solid coupling simulation model; step 3, analyzing the orthogonal test results of the orthogonal test design to determine an optimal combination of space pipeline structures. The vibration damping design method of space pipeline in strong vibration environment establishes a bidirectional fluid-solid coupling model for the space pipeline, and determines the structural parameters of the designed pipeline according to the comprehensive scoring method and the orthogonal test method, so as to obtain a scheme for optimizing the comprehensive performance of the pipeline, thereby the vibration of the space pipeline in strong vibration is reduced, and the stability andsafety of the pipeline system are improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline vibration reduction, and particularly designs a space pipeline vibration reduction design method under a strong vibration environment. Background technique [0002] Construction machinery under harsh working conditions, such as hard rock tunnel boring machine (TBM), mining machinery, etc., during the working process, the sudden change of load will inevitably cause strong vibration of the equipment, resulting in the vibration of the space pipeline installed on it. The strong vibration environment will not only increase the stress of the pipeline, causing the pipeline to be prone to stress fatigue damage, but also aggravate the fluctuation of the fluid in the pipeline. The fluctuating fluid will cause a large impact on the downstream actuators, which will affect the stability and working efficiency of the hydraulic system. , and even affect the entire construction progress. [0003] Pipeline desig...
