Research On The Reliability Tests In 1MN Deadweight Force Standard Machine

The characteristic of Deadweight Force Standard Machine is force precisio n, and it is the indispensable equipment in the measurement department, resear ch department and the production and force measurement instrument department.The text has made sub-level research aimed at 1MN Deadweight Force St andard Machine reliability test issues, and it has Proposed the main theories of 1MN Deadweight Force Standard Machine reliability test. To begin with, the article is based on the theories of component reliability test combined with AN SYS finite element analysis and according to its own characteristics to analyze the specific component of the test method; Further more, After ensure the rel iability of components, The Article is deeply studied the reliability test of the drive set in1MN Deadweight Force Standard Machine, Especially for the test overload factor in issues related to a detailed analysis of the demonstration. Th e text has innovatively cited the theory of reliability evaluation of solid rocket motors content and explored the overload factor of Drive set,Coefficient of v ariation, More over, In determining the loading on the test device using a lev er balance, to achieve a simple loading; what's more, After based upon analyz e the reliability of components and functional components, it made the analysis on the reliability tests for functional testing and performance testing of Force Standard Machine, And it Proposed the specific test method.In this section it is also innovatively increased protection circuit for debug ging issues that exist in the collision; finally, Establish a simplified model of the mechanical machine and used ANSYS finite element analysis to simulate i n the process of loading and unloading of the forces of complete appliance, an d got the condition state of 1MN Deadweight Force Standard Machine. Based on the 1MN Deadweight Force Standard Machine Problems of relia bility testing to ensure the reliability of the standard machine, Additionally, Th e study of its correlative technical essential and experimental method can popul arize to the homothetic testing machine field and other war industry,space eng ineering field, etc, it is vitally important for the reliability of large single mec hanical equipment.
