  • Application of modeling & simulation in a complex engineering system – I am covering hydraulic system of an off highway vehicle
  • An off-highway vehicle is a heavy machinery used at construction sites for carrying heavy loads. This part of the vehicle is known as a boom, which is controlled by hydraulic cylinders. A bucket, which is controlled in tilt in and tilt out movements by a bucket cylinder. The similar arrangement of boom & bucket we’ve in front of the vehicle The rear arrangement of the boom and bucket is to dig the mud from pile and front arrangement of the boom and bucket is to carry the heavy load
  • This slide shows loading cycle or 1 cycle of operation of a wheel loader. Into the pile, user is trying to fill the bucket and continuously rocking the bucket in the immovable pile. Back from pile, user is reversing the vehicle and holding the boom & bucket at some angle. In the load receiver state, user is raising the boom and dumping the mud in the load receiver and going back to the pile
  • This slide shows – what is new in the modern wheelloaders In the modern loaders, hydraulic circuit is designed and controls is upgraded for better performance e.g. to avoid leakages in the system, hydraulic ckt is redesigned. Fuel economy saving is one of the aspects, where several OEMs are focusing. Fuel economy can be saved by saving the pump power. Pump power can be saved by designing new controls techniques Modern loaders are of higher load carrying capacity OBD is included to ensure the fail safe operation
  • Now, coming to modeling & simulation activities in wheel-loader systems. We can create a complete digital prototype of the hydraulic systems to optimize design by identifying technical issues
