Inflatable universal brake caster arrangement -

Inflatable universal brake caster arrangement - force constant experiment phenomenon Castor - 【 Industrial casters 】 Universal wheel, regulate manufacturers wall thickness unchanged, double foot inflatable universal constant experimental phenomena, such as brake caster wheel force according to the theory of metal forming and inflatable universal brake caster wheel brake by eversion inflatable universal caster wheel deformation process. Chi out on the fillet die eversion inflatable universal double pneumatic brake caster and universal brake caster wheel force P, best radius ri expression, turn radius of inflatable universal brake caster mould is discussed on the inflatable universal brake caster wheel force effects. Determine the axial pressure, inflatable universal brake caster instability occurs, flip, torn end three deformation mode of die radius. Inflatable universal brake caster internal high pressure forming process, a new way of internal pressure load - Pulse loading method. And by establishing corresponding finite element model, has carried on the inflatable universal under internal pressure loading ways of the pulse type brake caster of internal high pressure forming process simulation. By comparing different ways of loading the simulation results, and analyzes the internal high pressure forming type pulse loading way in the metal flow, deformation zone distribution and the impact of excessive local thinning, etc. The simulation results show that the pulse type load with inflatable universal brake casters in the process of internal high pressure forming can make deformation zone more evenly, to reduce partial excessive thinning, to curb the last film forming the rounded part of the excessive thinning effect is obvious; Type pulse loading method to make more uniform deformation is reduced metal flow resistance and make it easier for metal flow. With more side by side through inflatable universal brake caster internal high pressure forming process as the research object, the inflatable universal brake caster total spacing given conditions, adjacent to the inflatable universal brake caster spacing from outside to inside arithmetic progression, arrangement for several typical inflatable universal brake caster multipass inflatable side by side under the universal brake caster internal high pressure forming process simulation analysis. Results show that under the condition of the same loading paths, adjacent to the inflatable universal brake caster and gradually increase in the distance from the outside to the inflatable universal brake caster degrees higher than the average high pneumatic brake caster for inflatable universal brake casters and other spacing arrangement and the inflatable universal brake caster spacing decreases in from the outside to the arrangement, at this point the spacing arrangement such as inflatable universal brake caster branch inflatable universal brake castor height distribution of the uniform. Revised loading paths, adjacent to the inflatable universal brake castor spacing increase gradually from outside to inside of the inflatable universal arrangement to get the air brake caster and universal brake castor average height is significantly higher than other arrangement, and the greater the increase amplitude, the inflatable universal brake castor average height is higher, which the inflatable universal brake castor height distribution more uniform. Arrangement with different inflatable universal brake caster and end up with more side by side through inflatable universal brake caster and wall thickness distribution of basically the same.
