摘　　要：利用分子动力学模拟方法定性分析影响金属铁与聚异戊二烯橡胶材料相互滑动过程中摩擦性能的多种因素.研究结果表明,橡胶/铁体系的摩擦力随着滑动速度的增加而增大;橡胶磨损率随温度增加而增大,温度对摩擦力的影响关系较复杂.在模拟条件下,提高铁块滑动速度能够显著降低橡胶的磨损率.研究结果为减缓聚异戊二烯橡胶材料与铁等金属物质的摩擦磨损,延长橡胶使用寿命提供理论基础.The molecular dynamic simulation method was used to qualitatively analyze friction properties between iron and polyisoprene rubber materials during a sliding process.The results showed that both the friction and rubber wear rate of the rubber/iron system increased along with the increasing of sliding rate;the rubber wear rate increased continuously with the increase of system temperature,while the effect of temperature on friction of the system was complex.In simulation condition,increasing sliding speed of the iron block effectively reduced the wear rate of rubber.The research results provided a theoretical basis for alleviating the friction and wear of polyisoprene rubber materials and prolonging their service life.
