Minimization of the thermal state of the hub

What is it about?

The problem of minimizing the thermal state of a hub–plunger in a friction pair has been solved by a linear programming method. It has been shown that the distribution of the thermal state of a hub–plunger friction pair can be controlled (minimized) by selecting the displacement function for the hub’s external contour points and the microgeometry of the friction surface. The closed system of algebraic equations obtained allows selection of the optimal geometric parameters of the friction pair, ensuring minimization of the thermal state of a hub in the design stage by numerical calculations. Knowing the optimal coeicients allows the best geometric parameters and the class of roughness of the treated internal surfaces of both the hub and plunger to be chosen at the design and manufacturing stage, ensuring increased serviceability of the friction pair elements under the repeated reciprocating motion of the plunger. http://www.tandfonline.com/eprint/VnygASk6pQGdth8BDwud/full
