【摘要】：为提高皮囊蓄能器的能量效率,介绍了新型复式蓄能器的物理模型,建立了复式蓄能器热力学系统动态方程组。基于Matlab仿真所得系统温度和压力变化情况,推导出复式皮囊蓄能器广义Maxwell力学模型,提出复式蓄能器热弹簧概念。基于新型力学模型的仿真表明,新型复式蓄能器比旧式皮囊蓄能器有更高的工作效率和更低的耗损率。对广义Maxwell力学模型、热弹簧概念和蓄能器工况参数的综合分析,为进一步改进和应用蓄能器提供新方法。
[Abstract]:In order to improve the energy efficiency of the skin sac accumulator, the physical model of the new compound accumulator is introduced, and the dynamic equations of the thermodynamics system of the compound accumulator are established. Based on the temperature and pressure change of the system simulated by Matlab, the generalized Maxwell mechanical model of compound skin accumulator is derived, and the concept of thermal spring of compound accumulator is put forward. The simulation based on the new mechanical model shows that the new compound accumulator has higher working efficiency and lower wear rate than the old one. The comprehensive analysis of the generalized Maxwell mechanical model, the concept of thermal spring and the working condition parameters of the accumulator provides a new method for further improvement and application of the accumulator.
