A method for pruefung of shock absorbers as well as roundup and circuit arrangement for carrying out this method

摘要

A method of testing vehicle shock absorbers, one at a time or in pairs, while on the vehicle by causing the vehicle to be jounced at least through the critical frequency of the suspension system and displaying the maximum down load exerted by the vehicle on its supporting structure to obtain a visual concept of the dynamic response of the shock absorbers. The method is practiced by apparatus in which the support for the vehicle wheels is oscillated at a constant amplitude and through a linearly increasing speed cycle to gradually carry the suspension system through its critical frequency where the down load of the vehicle on the support reaches a maximum, and in which electrical means is incorporated to obtain and display that maximum down load reading in terms of the dynamic response of the shock absorbers.
