[Finite element analysis of total hip replacement].

Total hip replacement is a very effective method to cure many kinds of hip joint illnesses. About a century ago, it was first used in clinic. Since then, total hip replacement has been well developed.

[Development of hip joint simulators].

Currently, hip replacement is an effective treatment for some hip joint diseases. The friction and wear of a prothesis in the human body are the main causes for the failure of joint arthroplasty. It is, therefore, very important to simulate the working conditions of a hip prosthesis in order to get an optimal design and successful clinical applications.

Analysis of the simulative experimental data related to the effect of the myocardial bridge on the blood flow of the coronary artery.

The compression of the mural coronary artery also exists in the diastole. We make a myocardial bridging simulator and build an experimental model to study the status of the compression. Through the simulative experiment, we make a numerical value simulation which depicts the effect of the myocardial bridge on the blood flow of the coronary artery during systole and diastole.

[Design and manufacture of mechanic modeling of fluid dynamics related to the myocardial bridging and mural coronary artery].

A model of fluid dynamics related to the myocardial bridginged and mural coronary artery was designed and manufactured according to the physical principle and characteristic of the mural coronary artery. The model can imitate systematically well the effect of myocardial bridging on hemodynamic change of the mural coronary artery under different controlled experimental parameter. The methodology is proved to be feasible and has good prosperity of experimental study.
