Description
Изобретение относитс к технической механике и может быть использовано при определении моментов инерции .The invention relates to technical mechanics and can be used in determining moments of inertia.
Целью изобретени вл етс рас- ,ширение технологических возможностей способа за счет проведени испытаний также и в полевых услови х.The aim of the invention is to expand the technological capabilities of the method by conducting tests also in field conditions.
Способ реализуют следующим образом .The method is implemented as follows.
На упругие опоры устанавливают машину, причем рассто ни h и h- вертикальной оси, проход щей через центр масс машины, до плоскостей, в которых расположены оси упругих опор, выбирают из соотношени :A machine is installed on elastic supports, and the distances h and h of the vertical axis passing through the center of mass of the machine to the planes in which the axes of elastic supports are located are chosen from the relation:
S СаЧ где С и С - коэффициенты жестк:остей опор,S SaC where C and C are the coefficients of the rigid: spine supports
. Возмущающей гармонической силой F, приложенной к мапщне, возбуждают вынужденные колебани -машины. Измен круговую частоту возмущающе силы, определ ют ее значение, при котором амплитуда угловых колебаний будет максимальной.. The perturbing harmonic force F applied to the machine excites the forced oscillations of the machine. By changing the circular frequency of the disturbing force, its value is determined, at which the amplitude of the angular oscillations will be maximum.
Момент инерции машины вычисл ют по формуле:The moment of inertia of the machine is calculated by the formula:
C,hf + C, 1 --- ---, .C, hf + C, 1 --- ---,.
Способ целесообразен при невозможности использовани специальных устройств, например подпружиненнойThe method is expedient when it is impossible to use special devices, for example, spring-loaded
