Method of calculating the influence of the suppression system on the autonomy of an armored combat vehicle

A method of calculating the effect vibrations sprung body and operation suspension system an armored combat vehicle on its autonomy has been developed. One main indicators is power reserve, which depends specific fuel consumption. In process moving over bumps, a significant part plant's energy, accordingly fuel, spent occurrence machine unsprung masses. Then energy these converted into heat in damping devices chassis. difficult road conditions, real tracks, losses average 10...15% plant power. resonant modes, when along harmonic profile irregularities, they can reach 30%. Calculation reduction costs will increase vehicle.
 The methodology based calculation balance longitudinal, angular vertical masses, deformation energies elastic elements suspension, rubber hinges guide tires, as well absorbed by devices, tires. Depending this balance, there either load and, accordingly, consumption, or it decreases becomes driving force. To calculate oscillations components necessary to use mathematical model movement bumps. All parameters machine, deterministic bumps high-speed mode are set. Amplitudes velocities longitudinal masses calculated from input data. For each kinematics, twisting angles torsions, forces amount their working bodies joints tires calculated. Next, magnitude sign change total at moment time determined. Based additional using efficiency coefficients engine transmission, supplied consumption determined.
 Thus, possible evaluate compare with other range vehicle, caused fluctuations system, depending type characteristics given speed modes. With help developed methodology, carry out structural parametric optimization kinematics order reduce vehicle. This technique be useful assessing expediency recovery purpose conditions vehicles.
