多功能摩擦传动实验机研制与实验研究
A Multifunctional Tribology and Transmission Machine and Experimental Investigation

针对目前摩擦学实验台接触形式单一、实验范围狭窄及边界条件不统一等问题，设计了一种新型多功能摩擦传动实验机。通过采用两个可在径向载荷作用下作可控相对运动的独立电机驱动主轴，实现多种接触形式的试件装卡，从而在高度统一的边界条件下进行摩擦磨损、传动性能测试及疲劳寿命检测等多种实验。实验结果表明：该实验机可为滑滚接触条件下典型零部件的摩擦与润滑机理研究、传动系统性能检测与动力学分析等提供可靠的实验平台，满足设计要求。
Aimed at the deficiencies of the single contact forms, limited experiment scope and inconsistent boundary condition in the research on tribology apparatus, a multifunctional tribology and transmission machine is developed under the consistent boundary condition. Employing two independent actuators which can make the relative motion to drive main shafts, it is allowable for various test pieces and thus can perform a series of tribology and transmission tests including friction, wear, transmission performance, contact fatigue under consistent boundary condition. The experimental investigation indicates that the machine provides a fundamental platforms for an interface friction, lubrication mechanisms, mechanics model,and kinematics analysis of transmission system, which meets the requirements
