Torsion of the torsion spring
Torsion springs are also called torsion springs, which is a complex design principle in all spring categories. The type changes are also very lively. Therefore, the theory involved in the design is also the most cumbersome.
The torsion spring rings are either tightly surrounded or separated and can be torsionally loaded (at right angles to the axis of the spring). The end of the spring can be wound into a hook or straight twist arm.
When the torsion spring is twisted, the material is in the tensile or shear state such as the calculation of the torsion degree. Therefore, the torsion angle limitation of the torsion spring is finally caused by the failure of the material. When the material undergoes plastic deformation, the original state cannot be restored. . Therefore, at the end, it is attributed to the tensile strength and shear strength of the material. Of course, the Von Mises stress calculated by the fourth strength theory is the maximum strength that the material can withstand. Combined with the length of the spring, the maximum allowable twist angle can be calculated.
