摘　　要：以阻尼连续可调减振器为研究对象,根据其结构特点和工作原理,对减振器的热力学特性开展了研究。建立了减振器热力学数学模型,结合减振器阻尼力和摩擦力,搭建了减振器热力学Simulink模型,进行了不同激励下的热力学仿真,并搭建实验台进行了实验验证。结果表明:相同激励下,工作电流为0 A时,减振器阻尼力热衰减最明显;建立的数学模型和搭建的热力学模型均具有较高精度,且计算效率较高,可用于减振器热力学特性的研究与预测。The thermodynamic characteristics of continuous damping control shock absorber are studied based on their structural characteristics and working principles.A thermodynamic mathematical model of shock absorber is established,and a thermodynamic Simulink model of shock absorber is constructed by combining damping force and friction force.Thermodynamic simulations are conducted under different excitations,and an experimental platform is built for experimental verification.The results show that under the same excitation,when the working current is 0 A,the damping force of the shock absorber exhibits the most significant thermal attenuation.The established mathematical model and the constructed thermodynamic model both have high accuracy and computational efficiency.The modeling method can be used for the study and prediction of the thermodynamic characteristics of shock absorbers.
