LABORATORY SYSTEM ENDURANCE TESTING OF MAJOR CAR COMPONENTS

Sophisticated tools were developed to evaluate the durability of car components. The idea is terms laboratory 'system' 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. Result 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.
