ANALOG LOADING TECHNOLOGY OF THE ELECTRICAL POWER CLOSED TESTER OF MECHANICAL DRIVE
[Abstract]The tester of meehanieal drive is an experimental platform used to comprehensively test the capabilities of transmissions.It can provide true and general design gist for the development of mechanieal transmissions and parts and verify the function and performance of the final products，it is a multifunctional device. Therefore,tester is widely used in mechanics，mine，auto and other industries.
Aimed at the defects existing in the current tester,the reconstructive seheme of analog loading is proposed in this paper. Computer control technology is used to realize the requirement of analog loading functions.
Firstly，the principle of the electrical control system of the electrical power closed mechanical drive tester is analyses. On the basis of these analyses，the feasibility of analog loading seheme is demonstrated in theory and the technical route is given according to the requirement of loading function of the test unit.
The results indicate that the scheme is feasible and the technical route is also reasonable and suitable. The analog loading to the test unit can be realized exaetly and stably， also the data acquiring & processing can be completed automatically. The realization of analog loading has amended the shortcomings of the original tester and greatly improved the technical level of the tester.
