Abstract

Through analysis of abrasive flow machining principle, this paper explores the design of equipment which is suitable for nozzle micro-hole abrasive flow machining. Based on catia，a cad software, three-dimensional models of the parts are drawn and assembled together. Based on the Finite Element Simulation software ansys, the finite element analysis of the key components of the equipment can be achieved. Through the result of simulation, the design of the equipment is reliable, and is able to satisfy the requirements of strength and rigidity. It offers the theoretical basis for optimizing abrasive flow machining equipment. Through the result of tests, the system of the equipment runs steadily and the ideal abrasive flow machining effects can be achieved.

Abstract

The test of moment of inertia has a wide range of applications in aerospace, vehicle engineering, precision machinery, motors and other fields, moment of inertia directly affects the reliability and performance of components or equipment, it is very essential to test the moment of inertia. By analyzing the principle of moment of inertia test, we could come to the conclusion that the theoretical value, the inertia of the disk, the period of the torsion swing of the standard body and the period of the empty disk of the moment of inertia and the moment of inertia of the standard body. By analyzing the measurement error, position error and damping during the test, we could reach the following conclusion that the test accuracy of the moment of inertia can reach 0.1%.
