摘　　要：讨论了变载荷作用下轴-滚动轴承系统动力学问题.利用Hertz公式和静不定问题的解法(力法)推导滚动轴承受力与变形关系的计算公式并得到数值解,以整个轴-滚动轴承系统为研究对象,利用ADAMS大型动力学仿真软件进行动力学仿真.以6310轴承和某试验台轴组成轴-滚动轴承系统为研究对象,研究了变载荷作用下刚性轴-滚动轴承系统、弹性轴-滚动轴承系统的幅频特性和变载荷作用下的动态响应.Dynamic performance of the mechanical system, which is composed of a shaft and two rolling bearings, is studied in this paper. First a rolling bearing 6310 is studied to obtain the formula between the applying load and the relevant displacement, and the problem is regarded as a static indeterminate problem and the Hertz theory is also used to solve it. Then the numerical solution is acquired. Two dynamical problems on variable loads are discussed for the system, one is to treat the shaft as rigid body and the other is to treat it as a flexible shaft. The special software ADAMS for dynamical simulation is used to solve the problems. The relation between amplitude and frequency, dynamic response of the system are obtained on variable load. Numerical results are available in mechanical engineering.
