Force Calculation And Calculation Software Development On Buried Heating Pipeline

Buries the placing to become our country district heating pipe network recommendation straight one system of laying, this domain's designers need a set of apply theory to reality urgently, introduced systematically buries the thermal energy pipeline stress analysis and the computational method reference and the related computation software straight, present paper compilation follow after this goal.Below the present paper contains six partial contents:The first part mainly outlines buries pipeline's basic concept straight. The research with opens straightens buries the placing heat supply pipeline stress to calculate software's basic mentality. Elaborated briefly domestic and foreign regarding buries the heat supply pipeline design calculation fundamental research straight the present situation. Synopsis topic origin, research content as well as present paper main research direction and work content.The second part elaborated the heating pipe network water power computation's content, needs to calculate the content and the formula, for the design calculation software water power computation module, provide the theory basis.The third part proposed the pipeline stress calculation and the stress checking calculation basic principle and the formula. Proposed regarding the different pipeline part the corresponding intensity condition, has determined the straight length of pipe and the corner length of pipe stress checking calculation method. According to pipeline's glide condition, divides into the pipeline the anchor section and the glide section, proposed does not have compensates buries the biggest friction length straight the concept and the computational method. Finally proposed the pipeline vertical stable checking calculation method and the smallest burying depth request.The fourth part regarding buries the placing heat supply pipeline's stability to carry on the theoretical analysis straight. Divides into the straight length of pipe the length of pipe the integrity stability analyses and buries the partial stability analyses straight. Discussed has buried the hot water heat supply pipeline's stability straight and buries the straight length of pipe to carry on the stable analysis directly. Gave had not considered when live load buried the hot water pipeline to satisfy the vertical stable straight smallest crown to fill in the depth, and gave the stipulation crown to fill under the depth the ascending pipe change-over portion biggest arrangement length. Using the classical board shell stability theory, buried the pipeline directly presses the crosswise external pressure and the axis under the function the partial jitter to carry on the thorough analysis, proposed determined buries heat supply pipeline partial stable straight checking calculation conditionThe fifth part introduced buries the placing heat supply pipeline action straight the form, as well as pipeline distortion characteristic and several basic concepts. The theoretical analysis and has inferred the pipeline stress and displacement's computation, has obtained the fixed pillar thrust force formula and according to the stress and displacement's formula lists by the graph form.The sixth part mainly introduced finally buries the placing heat supply pipeline support stress computation straight the software design contact surface, as well as the software should realize function.
