摘　　要：针对已有齿轮齿条惯容量不可在线调节问题,设计了一种基于可变传动比的齿轮齿条半主动惯容装置。对该装置动力学特性进行了分析,证明了该装置满足惯容特性,具备惯容量调节功能,并分析了设计中材料密度、锥形圆筒上下底面半径的选取问题;此外,基于SolidWorks建立了该装置的运动仿真模型,通过调节线性马达以及旋转马达的参数,分析了齿条和飞轮的运动状态;通过改变电机的位置、锥形圆筒的材料密度与上、下底面半径,探究了这些因素对惯容装置能量存储的影响。仿真及研究结果表明:齿条传动或线性马达对飞轮运动的影响大于电动凹槽对飞轮运动的影响,且该装置的传动比可以通过电机进行在线调节;锥形圆筒材料密度以及上、下底面半径对惯容装置的能量存储有较大影响,电机的位置调节对其的影响则相对较小。Aiming at the unadjustability of the existed rack-pinion inerters,a novel semi-active inerter was proposed based on an adjustable transmission ratio mechanism.The dynamic characteristics of the device were analyzed,and it was proved that the device satisfied the inertial capacitance characteristic and had the function of regulating inertial capacity;the selection of material density,upper and lower bottom radius of the cone cylinder in the design was analyzed.Moreover,a model based on SolidWorks was established.By adjusting the parameters of linear motor and rotary motor,the motion state of rack and flywheel was verified.The influence of these factors on energy storage was explored by changing the position of motor,the material density of cone cylinder and the radius of upper and lower bottom surfaces.The simulation results indicate that the influence of rack drive or linear motor on flywheel movement is greater than that of electric groove,and the transmission ratio of the device can be adjusted online by motor.The material density of conical cylinder and the radius of upper and lower underside have great influence on energy storage of the novel semi-active inerter,while the position adjustment of motor has little influence.
