Tractor Chassis Dynamometer Test Bench
Operation Philosophy
It is a customized special End Production Line Roller Test Bench for 2/3/4 wheeler vehicles (including multi-axle vehicles with 4×2 / 4×4 drive) Comparative test performance in Production & Quality Centers, Vehicle Repairing / Repairing / Re-building Centers, Educational Institutes, etc.
This system is especially designed to check following parameters of vehicle.
- Speedometer / odometer.
- Acceleration / deceleration.
- Waukesha Gas Engine is communicated by Modbus.
- Fuel consumption.
- 4W/2W function testing separately by high speed hall effect sensors.
- Hydraulic load test.
- Vehicle drive ability and Visual checks.
- Functioning of lights, vibration and leakages.
- Check vehicle gear transmission.
System Layout & HMI
Features
- System with 128 DI/DO , 8 AI/AO & 12 High Speed Input
- Vehicle Speed Accuracy is very important & we achieved within difference of 2-3 rpm
- Speed difference in PLC reading and Tachometer reading is less than 1 Kmph.
- MODBUS Ethernet communication with SCADA software for fast data transfers.
- Easy to diagnose machine alarms in GOT with troubleshoot manual PDF display on HMI screen.
- Critical point is to identify RPM from 12 different sensor in Front wheel roller
- RPM and result repeatability was also crucial part of Testing
