Grechaniuk M. Improvement of lateral dead-beat stability indexes of the articulated roadtrain with air suspension

Thesis is devoted to improving the lateral dead-beat stability indexes of articulated roadtrain by improvement its semitrailer air suspension. The mathematical model of articulated roadtrain transverse-angular oscillation with pneumatic suspension at run on inequality road surface which consider repositioning center of mass in system coordinates "articulated roadtrain - road surface" is specified. Offered advanced method of determination articulated roadtrain lateral dead-beat stability on angle of heel and lateral acceleration with allowance for height of a center of masses point and a point of overturn roadtrain semitrailer during its run. Created implement improve pneumatic roadtrain semitrailer suspension with divide pressure control system in pneumatic elements on the left and right boards of the roadtrain semitrailer. Received quantitative assessment roadtrain exponent lateral dead-beat stability on different speeds and loads of its semitrailer. Materials of dissertation work implements in JSC Ukravtobusprom (Lviv), at the OP and AP LLP (Vinnytsia) and at the Central research institute of arms and military equipment of Ukraine Armed forces (Kiev) and in Vinnytsia National Technical University academic activity.
