Evolution of pseudo-pinch point zone in multi-component batch distillation;

An approach was presented for determining the feasible clamping regions of fixtures.

The pinch point zone is one of the basic theoretical problems for distillation process, and it is very useful for the operation and design of the distillation column.

Analyses and Choices of Clamp Device for Drilling Thickness Left in the Punching Hole of the Piston Pin;

This article introduced welds installs jig's localization and the clamp structure and the general design request.

The features of small-sized jig designing are introduced, and how to locate and clamp flexibly in practical is mainly outlined.

Investigation of clamping reliability of bolted sphere nodes;

This paper is based on the example of processing the tire of pump stock's hole on coal mining machine,simply relates the course of design and machinery analysis about the mechanism,discusses the circumstance of force stress and deformation in detail in theory about thin liner in clamping of liquidity plastic and elastic centering.

The principle and its requirements of angle dividing and clamping equipment for bolted sphere nodes are put forward.
