LABORATORY SYSTEM ENDURANCE TESTING OF AUTOMOBILE MAJOR COMPONENTS

Sophisticated tools were developed to evaluate the durability of automobile components. The idea is termed the laboratory endurance testing where complex load inputs are applied to an automobile subsystem. The subsystem is defined as the suspension system, body system, steering system, drive train system and rotating system. Results of the laboratory simulation agreed with results from actual vehicle running tests. Among these, suspension system, body system and steering system endurance tests are discussed in detail in this paper. Introduction of the system endurance tests contributes to the reduction of testing cost and development time, and the improvement of testing accuracy and automobile reliability.
