摘要
针对连杆受力大、损坏严重的问题,从分析根据顶梁偏摆量设计液压支架四连杆的过程入手,简化模型写出了四连杆型液压支架的运动学和力学方程,以液压支架连杆受力绝对值之和、质量之和最小为目标函数,建立了多目标优化模型,求解采用优化效果较好的NSGA-Ⅱ算法,在matlab环境下编制成可视化计算程序.给出一设计要求实例,应用此程序优化设计及计算液压支架参数,通过对比分析表明,优化结果满足工程需要.
Contraposing the problems of connecting rod suffering high stress and severe damages, this paper analyzed the hydraulic supports four-bar connecting rod design process according to the deflective mount of the top beam, simplified support model, and derived the kinematic and mechanical equations. With the objective function of minimizing the sum of absolute link force and sum of link mass, the multi-objective optimization model was established. The NSGA-Ⅱ algorithm was used to obtain the optimized solution with a visual computing program under matlab environment. An example of the design requirements was provided in applying this procedure design and calculation parameters of the hydraulic support. Through the comparison and analysis, the optimization results meet the needs of the project.
