摘　　要：为研究直热后置式石蜡驱动器的位移输出特性,以石蜡的热力学特性为理论基础,建立了以正二十烷烃为相变驱动材料的直热后置式石蜡驱动器位移输出理论模型。制作直热后置式石蜡驱动器样机,搭建专用试验台,在不同温度负载和石蜡量下对样机的位移输出特性进行了试验。试验结果表明:在一定范围内,石蜡驱动器的输出位移随石蜡受热温度的升高和石蜡填充量的增大而增大,随负载的增大而减小;理论计算与试验的结果吻合良好。A prototype was made.In this paper,to study the displacement output characteristics of direct-heat post-paraffin paraffin actuator,Based on the thermodynamic characteristics,a theoretical model of displacement output of direct-heat post-paraffin paraffin actuator using normal paraffin wax as phase change driving material was established.A special test bed was built for the driver,and the displacement output of the direct-heat post-installed paraffin actuator was tested under different temperature and load conditions.The results show that in a certain range,the displacement output of the paraffin actuator increases with the increase of the heating temperature and filling amount of paraffin,and decreases with the increase of the load weight.
