基于压力变化的金属橡胶阻感参数数学模型构建

Construction of Mathematical Model of Resistance Parameters of Metal Rubber Based on Pressure Change

基于压力不断变化,构建了金属橡胶阻感参数数学模型。通过详细介绍金属橡胶内部组织结构,构建脉冲电流烧结系统,依据金属橡胶用不锈钢丝螺旋结构,采取实验测定与曲线拟合方式,构建金属橡胶足感参数模型。试验验证结果表明,金属橡胶等效电阻与电感数学方程可切实表明不同压力变化状态下参数变化趋势;在压力保持一定的基础上,金属橡胶等效电阻与电感可明确为定值形态,其有利于准确确定烧结时间与电流;在金属橡胶烧结时,受内部不锈钢丝挤压接触影响,逐步向外层扩张,等效电感遍布在外层范围内,而电流则处于中心位置。

Based on the constant change of pressure,the mathematical model of resistance parameters of metal rubber is constructed.By introducing the internal structure of metal rubber in detail,a pulse current sintering system is constructed.Based on the spiral structure of stainless steel wire used in metal rubber,the experimental measurement and curve fitting method are adopted to build the foot feeling parameter model of metal rubber.The experimental verification results show that the mathematical equations of metal rubber equivalent resistance and inductance can effectively can effectively indicate the parameter changing trend under different pressure changing states:on the basis of maintaining a certain pressure,the metal rubber equivalent resistance and inductance can be clearly defined as a fixed value form,which is conducive to accurately determine the sintering time and current:when the metal rubber is sintered,it is affected by the internal stainless steel wire extrusion contact,and gradually expands to the outer layer.The equivalent inductance is distributed in the outer layer and the current is in the center.
