摘　　要：空间红外遥感仪器多采用双轴承高速转动结构,仪器的失效往往是由于转动部件轴承的失效而引起。本文以调制系统为例,在MSC.ADAMS软件环境下建立其动力学仿真模型。通过多次仿真,模拟出了轴向载荷以及径向载荷与轴承接触应力之间的关系。分析结果对于红外遥感仪器转动部件的设计具有指导意义。Most of space remote sensors use high-speed rotation mechanisms with two bearings. The failure Of those instuments usually results from the trouble of the bearings used in rotational parts. In this paper, a dynamic simulation model for modulating systems used in space remote sensors is established by using a MSC.ADAMS software. Through simulation, the relations of axial and radial loading to the contact stress of rolling bearings are obtained. The analysis result is of significance to the design of the rotational parts for space remote sensors.
