RESEARCH ON DYNAMIC CHARACTERISTICS OF THREE-DIMENSIONAL FLOW FIELD OF LABYRINTH SEALS

Jixie qiangdu (2012)

Zhong Li

The dynamic characteristics of labyrinth seals play an important role in the dynamic characteristic of the rotor-seal systems.Therefore,researching on dynamic characteristics of the labyrinth seals is necessary.The three-dimensional model of the straight seal is made and the rotating reference frames are used in the computational fluid dynamics(CFD) software.The method of used rotating reference frames alters the unsteady flow flied into the steady flow flied and reduces the time and work of the calculation of CFD.The effects of parameters of the flow field on the dynamical characteristic and leakage are further discussed.The results present that the parameters of the labyrinth seals have the effect in dynamic characteristics of the rotor-seal system.When the gas in the labyrinth seals is transonic,the dynamic characteristic and leakage of the labyrinth seals has a change.The results of researching on dynamic characteristics of the labyrinth seals provides a basis for engineering design.

Residual Strength Analysis of Stiffened Aluminum Panels with Widespread Fatigue Damage

Advanced materials research (2008)

Zhong Li Sen Ge Guo Zhi Lv Li Chen Hui Liang Ding

Widespread fatigue damage (WFD) is an important concern of aging aircrafts. Residual strength of stiffened panels with widespread fatigue damage was evaluated by an engineering approach and a finite element method respectively. Nine stiffened panels with three types of damage were tested for their residual strength. The predictions are in good agreement with the experiment results and it is shown the methods could be used in an engineering practice for the residual strength evaluation with the acceptable accuracy. It can be seen from this research that WFD could result in significantly reduction in the residual strength of stiffened panels.

The Application of Compound Powder Binder in Foundry

Rejiagong gongyi (2000)

Zhong Li

Compound powder binder is produced by special treatment using main raw strarch of more than 80% branch chain and esterification starch with good water resistant. It has higher strength and certain hydroscopicity resistant and poision free and no gas evolution and been simple than that of synthetic grease sand, and its technology equipment is the same as that of synthetic grease sand and total cost of this binder is lawer than that of grease sand. It is an binder with no environment protection problems.

Structure optimization research of forging box of 10 MN precision hydraulic forging machine

Journal of Machine Design (2011)

Zhong Li

The structure strength finite element analysis of the forging box of 10 MN four hammer precision hydraulic forging machine was carried out by using ANSYS software,optimal structure design for the forging box was carried out by taking the stress at the forging box as the object.By taking the various dimension parameters as optima design variables and taking minimization of the unit stress at fracture as the target,the optimum structure design program(ODPST) for the forging box was made to carry out optimization of its structure.Through the optimization of forging box structure,maximum stress at fracture is reduced by 15.5%.The improvement effect of the forging box strength is obvious, prolonging its life operation.
