ENGINEERING PROJECTS ACCOMPLISHED
We have successfully executed more than 150 testing projects in this area. We are providing end to end solution to various OEMs in India, right from Instrument support, Measurements & data analysis/post processing till report generation, using our state of the art facilities under one roof.
Just to quote, few examples for kind of Projects we have executed.
1. Complete Vehicle Handling Comparison including Instrument set up, measurements, data analysis/post processing and report generation for Indian SUV’s & Indian Cars done at VRDE Test Tracks. Various dry & wet handling trials conducted like “J” Turn, Slalom test, Double Lane Change, Steady State Circular trials etc.
2. Complete benchmarking trials conducted for small cars including CSFC, Coast Down, Cooling trials, Gradient, Acceleration, Braking, Turning Circle, Steering Effort &Returnability and various Handling trials.
3. Fuel Efficiency City & Highway Drive cycle measurement including Gear Position, RPM, Speed, GPS parameters, Fuel Consumption using DFL Sensor, Axle Torque etc. for SUV & cars (back to back). Complete data analysis including report generation containing % utilization for various parameters.
4. ABS Performance Evaluation for Cars using complete Instrument set up at VRDE & WABCO Test Tracks for an Indian Car Manufacturer company.
5. Transient Handling Trials using Steering Robot & Data Analysis (time as well as frequency domain) for an SUV at VRDE Handling Test track. Various tests like Frequency Response, Step Steer, Sine test, On Centre Handling were carried out.
6. Cooling Trials & Temperature mapping in Trucks, Tractor trailers & Buses using more than 256 sensors at various locations (Temperature & Pressure), coolant flow measurement in static & dynamic condition, Coolant System verification trials etc. These trials conducted multiple times and on variety of vehicles.
7. Transmission oil Temperature measurements, temperature measurements of rotating parts for disc brakes & drum brakes etc. during brake test.
