Zusammenfassung:FIELD: cargo-hoisting machines; estimation of strength of structural members, dynamic stability and safety of such machines. SUBSTANCE: method of determination of dynamic forces acting on structural members of boom hydraulic manipulators at abrupt change in boom speed with cargo suspended from it by means of flexible member is based on use of analytical dependences relating the actual magnitudes of mass, geometric, rigidity, speed and other parameters of structural members on level of loads being determined. Dynamic forces are determined taking into account occasional nature (probable deviation from average magnitudes) of parameters having effect on level of loads. EFFECT: enhanced reliability of determination of dynamic forces. 2 cl, 4 dwg
