The invention discloses an automotive suspension
vibration damper energy characteristic testing
system and an automotive suspension
vibration damper energy characteristic metering method. The automotive suspension
vibration damper energy characteristic testing
system comprises a rack, a
crank connecting rod slide block mechanism which is arranged on the rack and can generate sine movement, a clamp for fixing a vibration
damper, a lower mounting bracket, a speed sensor, and a
force sensor for measuring a damping force. The
crank connecting rod slide block mechanism is used for realizing
reciprocating motion between a stretching
stroke and a compression
stroke of the vibration
damper and is provided with a
crank, wherein a crank connecting rod can perform circumferential motion around the other end point of the crank. The top end of the crank connecting rod is connected with the lower mounting bracket, thereby driving the vibration
damper to perform vertical movement along with the crank connecting rod, wherein a slider is driven by the crank connecting rod and performs up-and-down motion. The metering method is based on the automotive suspension vibration damper energy characteristic testing
system, wherein
computer image identification technology is applied on solving and calibration for vibration damper
indicator diagram. Furthermore the metering method is a quantitative analyzing method for energy absorbed by the vibration damper, thereby supplying a new evaluation method and a quantification standard for performance testing of the vibration damper.
