摘　　要：为了使石蜡驱动器在有限体积下具有更好的力输出特性,基于ANSYS-Fluent模块,对某活塞式石蜡驱动器的内径进行改进设计。利用正交试验法模拟四种不同内径的活塞式石蜡驱动器在受热过程中石蜡的相变过程,得到石蜡完全熔化后腔体内部压力及驱动器的输出力特性,并与初始内径石蜡驱动器的输出力进行对比。结果表明:石蜡驱动器内径为18mm时,石蜡驱动器的力输出效果最好,进而为后续石蜡驱动器的结构改进提供参考。In order to make the paraffin wax actuator have better output characteristics under limited volume,this paper adopts ANSYS-Fluent module in the study to improve the design of inner diameter of a certain piston-type paraffin wax actuator.Orthogonal test method is applied to simulate the phase transition of the paraffin wax during heating process of 4 piston-type paraffin wax actuators with different inner diameters to obtain the internal pressure of the cavity and output force characteristics of the actuator after the paraffin wax has completely melted,and have the output forces compared with the paraffin wax actuator of initial inner diameter.The results show that best output force can be obtained when the inner diameter of the paraffin wax actuator is 18mm,which can provide reference for further structural improvement of the paraffin wax actuator.
