Contact Pressure of Loose-Fitted Tyre under Intermittent Contact

摘要

The total loads between kiln support are transmitted to the shell cross-section at tyre as shearing forces. According to the character and the condition of shell deformation and force balance, the mathematical models of contact pressure have been set up between tyre and shell under intermittent contact. The contact zones and contact pressures between tyre and shell are solved when the support reactions and gaps are variable. The results show the contact pressures increase with the increase of support reactions and gaps, the contact zones are proportional to support reactions, and inversely proportional to the gaps, which provide the reason for sound axis alignment and gap design.
