摘要

机械系统可靠性分析是工程领域的一个主要研究重点。本研究旨在解决具有复杂机构和非线性可靠性方程的复杂机械系统的问题。为此,我们提出了一种融合响应面和灵敏度分析方法的可靠性分析和优化方法。通过建立响应面模型来拟合复杂的状态函数并求解可靠性参数,然后通过误差灵敏度分析来确定机械系统的可靠性调整策略,从而全面形成复杂机械系统的可靠性评估和优化方法。最后,将这些方法应用于圆柱形材料运输装置,初步实现了可靠性评估和平均可靠性优化目标。研究结果可为评估和提高复杂机械系统的可靠性提供理论框架和研究机会。

Reliability Analysis and Optimization Method of a Mechanical System Based on the Response Surface Method and Sensitivity Analysis Method
Mechanical system reliability analysis constitutes a primary research focus in the field of engineering. This study aims to address the issue of complex mechanical systems with intricate mechanisms and nonlinear reliability equations that are challenging to solve. To this end, we present a reliability analysis and optimization methodology that merges the response surface and sensitivity analysis methods. A comprehensive formation of reliability assessment and optimization of complex mechanical systems is achieved by creating a response surface model to fit the complex state function and solving the reliability parameters, followed by an error sensitivity analysis to determine the mechanical system’s reliability adjustment strategy. Finally, these methods are applied to a cylindrical material transport device to preliminarily realize the reliability assessment and average reliability optimization goals. The study’s findings may offer a theoretical framework and research opportunities to evaluate and enhance the reliability of intricate mechanical systems.
