中文摘要: |
针对汽车胎压监测装置在装配和运转过程中,存在橡胶元件易损坏的问题,采用有限元法研究了元件与轮毂过盈量对橡胶材料所受应
力、应变的影响。利用虚功方程确定了橡胶Mooney Rivlin模型的应力 应变方程,通过单轴拉伸试验得出橡胶材料模型参数,建立了胎压监测装置的有限元模型
。分析结果表明当过盈量为0.4 mm时既能保证装配质量又能减小运转过程中橡胶所受的应力,从而延长其使用寿命。 |
英文摘要: |
There is the problem that the rubber components of the automobile tire pressure monitoring device are easily damaged during assembly and operation,
the influence of the interference between the component and the hub on the stress and strain of the rubber material is studied by the finite element method. The stress strain equation of
rubber Mooney Rivlin model was determined by the virtual work equation, the rubber material model parameters were obtained by uniaxial tensile test and the finite element model of tire
pressure monitoring device was established. The analysis results show that when the interference is 0.4 mm, the assembly quality can be guaranteed and the stress on the rubber during the
operation can be reduced, thus prolonging the service life. |
