针对可倾瓦轴承润滑的特征，开发了一种新型前缘沟槽型(LEG)三瓦可倾瓦轴承;为获取该可倾瓦轴承的试验参数，研制了一套具有自动采集数据、实时分析数据等功能的可倾瓦轴承动态特性测试试验台;对比分析了浸润式滑动轴承与前缘沟槽型滑动轴承的轴瓦温度特性;采用有限差分算法理论计算了该轴承的动态特性参数，采用扫频激振方法试验研究了该轴承的8 个动态特性参数，并通过对比分析理论计算与试验结果验证了试验方法的有效性． 研究表明，所开发的滑动轴承具有较好的温度特性及刚度阻尼特性．

Firstly，according to the lubrication characteristics of tilting pad bearing，a novel three-pad tilting pad bearing with leading edge groove (LEG) was proposed． Secondly，in order to obtain the test parameters of the bearing，a dynamic performance test rig with the functions of automatic data acquisition and real-time data analysis was developed． Then，the temperature characteristics of flooded bearing and LEG bearing were analyzed in a com-parison way，and eight dynamic parameters of tilting pad bearing were obtained respectively via finite difference al-gorithm and frequency sweep excitation test． Finally，the effectiveness of the proposed test method was verified by a comparison between the theoretical results and the test ones． It is found that the developed bearing is of good tempera-ture，stiffness and damping characteristics．
