摘要：

为了减小硬岩掘进机（TBM）工作过程中产生的随机振动对其液压系统中的液压直管道位移和应力的影响，建立了随机振动环境下液压直管道设计模型，并采用实验验证了模型的正确性。分析了管道结构参数对液压直管道应力响应和位移响应的影响规律，发现液压直管道应力响应和位移响应随管道内径和管道长度的变化趋势是相反的，而随着管道壁厚的增大，管道最大位移响应和最大应力响应均增大。采用基于遗传算法的多目标优化算法对随机振动环境下两端固支液压直管道的结构参数进行优化设计，对比分析了设计前后管道的应力响应和位移响应，结果表明，设计后的管道最大位移均方值降低了约16.21%，最大应力均方值降低了21.04%。研究结果可为随机振动环境中液压管道的抗振设计与选型提供理论依据。

Abstract:

For reducing the impact of random vibration generated by Tunnel Boring Machine (TBM) on the displacement and stress of hydraulic straight pipe in its hydraulic system, a design model of hydraulic straight pipe under random vibration environment was established, and the correctness of the model was verified by experiments. The influences of pipeline structural parameters on the stress response and displacement response of hydraulic straight pipeline were analyzed. It is found that the stress response and displacement response of hydraulic straight pipe change with pipe diameter and pipe length in the opposite direction. The multi-objective optimization algorithm based on genetic algorithm was adopted to optimize the structural parameters of the fixed-supported hydraulic straight pipeline at both ends under the random vibration environment. The stress response and displacement response of the pipeline before and after the design were compared and analyzed. The results show that the mean square value of the maximum displacement of the pipeline after the design was reduced by about 16.21% and the mean square value of the maximum stress was reduced by 21.04%. The research results could provide a theoretical basis for the design and selection of vibration resistance of hydraulic pipeline in random vibration environment.

Key words: hydraulic straight pipe, fluid-solid interaction, random vibration, optimization design
