摘要
Abstract
The chief object of this research is to survey the influence of temperature on the constraint force of bearing plate,and analyze the law of strain and constraint force in cooling process with different initial pressures applied.The author has satisfactorily come to the conclusion that cooling can bring to shrinkage strain as high as-727 με with pressure reduced.The higher the initial pressure is applied,the cooling has greater slightly effect on the constraint force of bearing plate.Compensation formulas are provided for correcting the constraint force.关键词
