| description | ABSTRACT This work deals with optimizing the synthesis error in an eight‐bar Peaucellier—Lipkin mechanism, for its dimensional synthesis and applications in load‐lifting machines. A new method for the formulation of the problem of maximizing the objective function is proposed and makes it possible to obtain from the PSO algorithm a minimum synthesis error emin = 9.07E−06 mm for the generation of the straight trajectory when the search interval for the lengths of the bars is [1 mm, 15 mm] and a minimum error emin = 1.47E−04 mm when the search interval is [1000 mm, 15,000 mm]. For 10 simulations in Case 1 the average convergence time is tm = 55 s with the largest iteration at 10 (for t = 159 s); for 100 simulations in Case 2, the tm = 229 s with the largest iteration at 136 (for t = 2294 s). The minimum error of Case 1 is compared with the results of authors in the literature on the generation of the right trajectory because the search space is approximately equal. In the literature, emin = 0.648358 mm with the GA‐DE algorithm in 2010, emin = 2.3667E−005 mm with the MKH algorithm in 2016, emin = 0.027145 mm with the SAP‐TLBO algorithm in 2017, emin = 3.7E−4 with the GA algorithm in 2019. This new method brings a plus, because even when the search space is very large, the algorithm converges quickly and it allows the study to be extended to the generation of circular trajectories by just modifying the ratio between the frame bar and the crank bar. The practical implications of achieving an error as low as 9.07E−06 mm are the design of high‐precision industrial machines with reduced vibration, noise, and premature wear of joints. The results of the post‐design FEM analysis show that for a 1.4571 steel (X6CrNiMoTi17‐12‐2) with a thickness of 50 mm and a joint with a radius of 500 mm, the mechanical device obtained can support a load of 1500 kg. |
