Fatigue Test Systems (FTS)
GRIPS AND FIXTURES
Shock absorber manufacturers are conscious about the need to ensure that manufactured parts conform to required specifications. Over two million tests are performed every month on over a hundred BISS shock absorber test stations with practically all globally reputed manufacturers. Some of these systems are more than twenty years old and have seen over 50,000 hours of operation. Production testing involves a cycle time of just 7 to 20 seconds and leaves no time to ensure proper alignment of the part. BISS R&D was able to come up with gripping arrangement that are self aligning by design and principle of operation.
DFT systems, produced by BISS, are being widely used in automotive industries especially those manufacturing shock absorbers for vehicle (motor bikes, cars, buses, trucks, trains etc) suspensions. These shock absorbers, using DFT systems, are typically tested for their performance, durability and quality check. The BISS make DFT systems are typically classified based on: the stations (single station or dual station); the plants (production or R&D); the application (performance, durability, quality check); the drives (servo-hydraulic, slider-crank driven, electromagnetic); the orientation (tilting system / non-tilting system); the grips (manual, automatic); speed (low speed up to 1.0 m/s; high speed up to 6.0m/s); the mobility: (stationary and mobile). The typical common unique selling features of these systems are as follows:
