Estimation of Dynamic Qualities of Undercarriage Machines

The dynamic qualities are examined theoretically with designing new machines or by experiment for the existing transport machines. The methods used to estimate them are based on the assumption that the resistance with running is a constant quantity or it changes only according to the speed of movement. The influence of road conditions and of the loading and speed operation modes is not completely taken into account that reduces the accuracy of the estimation. The paper presents methods of estimating the undercarriage machine dynamic qualities considering the multi-factor influence of the operation conditions on the energy losses.
