【摘要】：为使液压支架铰链四杆机构在采高区内具有近似直线轨迹,可利用连杆平面上的拐点性质综合这类四杆机构。以指定采高区内直线偏差最小为目标,以满足Grashof准则、杆长协调、角度限制等为约束条件,建立综合液压支架近似直线导向四杆机构的6参数约束优化模型。结合Deb约束处理可行性规则,应用差分进化(Differential Evolution,DE)算法求解该约束优化问题。给出综合实例,仿真结果表明,该方法是可行有效的。还比较了DE算法与另外3种智能算法求解该机构综合实例的优化性能。数值试验显示,DE算法的收敛速度、收敛精度和稳健性等性能指标优于3种对比算法。
[Abstract]:In order to make the hydraulic support hinge four-bar mechanism have an approximate straight line track in the mining height region, this kind of four-bar mechanism can be synthesized by using the inflexion property of the connecting rod plane. The aim is to specify the minimum line deviation in the mining height zone, to satisfy the Grashof criterion, and to coordinate the rod length. Angle restriction is the constraint condition, and a 6-parameter constraint optimization model is established for the four-bar mechanism with approximate linear guidance of the hydraulic support. Combined with the feasibility rule of Deb constraint treatment, The differential evolution evolution (DEE) algorithm is applied to solve the constrained optimization problem. A synthetic example is given and the simulation results show that, The method is feasible and effective. The optimization performance of DE algorithm is compared with that of other three intelligent algorithms. Numerical experiments show that the convergence rate of DE algorithm is higher than that of other three intelligent algorithms. Convergence accuracy and robustness are better than the three contrast algorithms.
