Reading results into the database (SET command) will update the current
displacement and force boundary conditions in the database with the
values from the results file for that load set. Note that any
subsequent solutions will use these values unless action is taken to
either SAVE the current values or not overwrite them (/EXIT,NOSAVE).

Рис.10 Результаты термического исследования
на режиме номинальной мощности
Осевое распределение температуры на номинальном режиме и режиме холостого хода показывает уменьшение температуры от днища поршня к его внутренней поверхности. Такое распределение объяснимо непосредственным воздействием высокой температуры только на днище поршня. Радиальное распределение температур на тех же режимах показывает, что максимальные значения температуры находятся в центре днища поршня.
Таким образом, была решена задача о распределении температур в поршне на режиме холостого хода и номинальной мощности.
