Аннотация
Рассмотрена задача расчёта изгиба судового валопровода с учётом деформаций кронштейна и деформации вкладыша кормового подшипника, представленного нелинейным упругим основанием. Предложен обобщённый метод релаксации в последовательных приближениях, обеспечивающий сходимость расчётов в задачах с обратными связями. Эффективность применения метода по сравнению с методом простых итераций показана на примере расчёта изгиба типичного проекта валопровода, имеющего кронштейн
