For convenient engineering applications,a proximate calculation formula for polar moment of inertia and twisting stress of hollow shaftwith radial opening has been derived,based on the theory of material mechanics.Using the above proximate calculation formula,an project example'twisting stress calculation and radial opening structure improvement have been dis-cussed and given,project implementation results showed that the improvement is effective.Then the ANSYS checking calculation has done,the results of formula calculation and ANSYS calculation are similar.So the proximate formula may serve as reference and applying for twisting stress calculation and design of hollow shaft with radial opening in engineering.
