查询词典 contact area

Through field measurement for the contact pressure of box foundation with Ⅰ shaped plane of a high rise building on cobble subsoil, the distribution law of the contact pressure has been diagrammed. At the same time, the contact pressure has been calculated with finite compression layer model, which is well accordant with the measured result. The relative error of average value for the measured to the calculated contact pressure is 6.9%. This shows that the numerical calculation is right.

The computation model of two-point contact (for cone-tread) and conformal contact (for worn-tread) resulting from wheel flange close to rail is firstly established in this paper. A detailed analysis is made of the wheel/rail contact force, contact status and wheel/rail stress distribution on the different action of tractive forces and transverse forces. We draw some important conclusions, one of which is that the locomotive adhesion performance will decrease with the increase of transverse forces between wheel and rail.

Initially, assuming that the contact between cam and tappet is"dry contart", a dynamics model of Hertzin contact stiffness and impact damping is established. Next, with dynamic load on cam—tappet pair from the model, an analysis is made both to unsteady EHD oil film in cam—tappet pair under condition of full and partial lubrtication and to wear characteristics of cam profile. then, according to the fact that the lubrication in cam—tappet contact surface is EHD lubrication, taking the interaction between stiffness and damping of unsteady EHD oil film and rigidity of solid object contact into account, a dynamics equation of valve train relating to the dynamic effect of EHD oil film is built up and solved. Consequently, a further study is made on the dynamic characteristics of valve train under interaction of EHD oil film dynamic behavior and the problem of EHD lubrication in cam—tappet pair. Finally, the dynamic effect of full and partial EHD oil film is studied accordingly.

In order to distinguish these two types of transitions, a state recognition method is introduced. We firstly propose a variable contact set in which the contact points on the robot body are defined to represent the alternation of the contact states logically. Then, by predefining thresholds for the contact forces, the state transition can be well recognized.3 As another research topic, the local tracking control according to the pre-acquired state transition trajectories plays an important role in realizing the non-regular motion for the humanoid robot.
