FIELD: testing equipment designed for research and operational development of transportation facilities according to noise and vibration comfort. SUBSTANCE: proposed frame-platform includes load-carrying spatial skeleton construction on which power unit comprising permanently joined hollow longitudinal spars, hollow transverse spars and hollow vertical columns, aids for assembly, vibration insulation and attachment of separate standard and peculiar parts, units, systems and sets are mounted. Salient feature of first variant of structural implementation of this frame-platform lies in filling of spaces of tubular skeleton structure with vibration and noise damping substance. In this case aids for attachment of power unit are located both on front, center and rear parts of it so that power unit can be installed both lengthwise and transverse to longitudinal axis of frame-platform. According to another variant of structural implementation of proposal load-carrying skeleton structure is equipped with separable special underframe on which directly power unit made of hollow profiles is installed. Tubular spaces of profiles are filled with vibration and noise damping substance. Assembly attachment members of underframe are intended for its rigid or vibration- insulating attachment along longitudinal axis of frame-platform in permissible range of geometric overall parameters and limits which inscribe in dimensions of skeleton structure. Both variants of structural implementation of multipurpose load-carrying frame-platform can be used specifically at large automobile plants, scientific research and designing organizations in the course of design, operational development and switch to commercial production of new model series of automobiles. EFFECT: increased objectivity and informativity of research, decreased cost, labor input and shortened time to conduct experiments. 5 cl, 16 dwg
