基于有限元分析的一体式台球杆力学性能评价

Evaluation of Mechanical Properties of Integrated Billiard Cue Based on Finite Element Analysis

为探究台球杆杆体材料的选择依据,采用有限元分析法评价不同树种木材制作的台球杆杆体的力学性能。杆体材料选取白蜡木(Fraxinus chinensis)、榉木(Zelkova schneideriana)、槲栎(Quercus aliena)、槭木(Acer mono)、降香黄檀(Dalbergia odorifera)和核桃木(Juglans regia)等6种木材,借助ANSYS Workbench仿真呈现台球杆击球时碰撞情况,分析不同材料台球杆的力学性能:通过对比不同台球杆击球后台球获得的速度值大小,判断杆体传力性能优劣,并根据台球杆在击球过程中承受的最大应力值判断其强度性能。结果表明:6种材料的台球杆中,白蜡木台球杆的传力性能最佳,而降香黄檀台球杆的传力性能最差,台球杆的传力性能与木材密度、ER、ET、μRT、μLT呈现负相关,与GLT、GLR和μLR均呈正相关,6种台球杆都具有足够的强度保证在击球时台球杆不发生破坏。

To explore the basis for material selection of the shaft in billiard cues,this study employs the finite element analysis method to analyze the mechanical properties of billiard cue shafts made from different wood species.There are six materials selected including:Ash(Fraxinus chinensis),Beech(Zelkova schneideriana),Oriental White Oak(Quercus aliena),Maple(Acer mono),Dalbergia odorifera(Dalbergia odorifera),and Walnut(Juglans regia).With the aid of ANSYS Workbench simulation to present the collision situation when the billiard cue strikes the ball,the mechanical properties of billiard cues made of different materials are analyzed.By comparing the speed values obtained by the billiard balls after being struck by different billiard cues,the superiority and inferiority of the force transmission performance of the shafts are determined,and the strength performance is evaluated based on the maximum stress endured by the billiard cues during the striking process.The results show that for the force transmission performance of the billiard cues,the Ash cue can exert the best force transmission performance,while the Dalbergia odorifera cue has the worst force transmission performance.The force transmission performance is negatively correlated with density,ER,ET,μRT,andμLT,but positively correlated with GLT,GLR,andμLR.All six billiard cues have sufficient strength to ensure that the billiard cues will not be damaged when striking the ball.
