Preventive rail grinding was demonstrated to produce significant benefits to BNSF Railway in a two year test program on their Pacific Northwest territory between 1998 and 2000 and was subsequently cascaded to the entire BNSF system by 2001 [4, 4]. The preventive rail grinding model was designed to remove RCF cracks using a single pass at
Two experimental procedures for the determination of the grinding model's parameters are presented. Simulations are performed to validate the grinding model. The determined model is found to be a valid representation of the grinding process that should prove useful in adaptive control with real-time parameter estimation.
Then, a grinding dynamics model based on deformation is established, and an adaptive iterative constant force control is proposed for complex robot belt grinding process, which overcomes the ...

Modelling and Control of Ball Mill Grinding. Dynamic experiments were performed in a continuous open-circuit 40×40 cm ball mill using a pseudo-random binary sequence of the feed rate and measuring the variations of the discharge particle-size distribution. The impulse response is calculated by a cross- correlation technique.
