| Abstract: | When the eddy current dynamometer is used to test the dynamic performance of the engine,the mechanical accident appeared seriously damage the dynamometer system.This paper analyzes the variable working conditions when the dynamometer system is damaged in the test,and attempt to find out the causes of the collapse of the dynamometer system.The reasonable suggestion for setting and structure of the working conditions on the dynamoneter system is made to prevent the similar accident. |
