Crankshaft parametric computer modeling system

Abstract

The present invention discloses a crankshaft parameterized computer modeling system which comprises a foreground human-computer interface part and a background core computer part, wherein, the background core computer part comprises a welcome interface module, a main data structure initialization module, a graphical interface module, a button command button module, a file output module, a data check module, a dynamic help module and a clock module. The foreground human-computer interface part comprises a parameter conducting module, an input selection module, a parameter input module, an operating command selection module, a dynamic help module and a clock display module. The invention is characterized in 1) strong parameterized modeling capacity, 2) complete data error checking capacity, 3) good human-machine interaction and 4) good compatibility and portability. The invention provides instructional advice for the adjustment of the finish machining and the machining technique, optimizes the machining technique, improves the finish machining efficiency and the machining quality of the crankshaft and the using efficiency of the crankshaft special lathe and reduces the manufacturing cost.

Description

technical field [0001] The invention relates to a computer modeling system for objects with complex shapes, in particular to a crankshaft parametric computer modeling system secondary developed on the basis of the existing computer analysis system. Background technique [0002] Due to the huge weight, size and investment of the crankshaft of a large marine diesel engine, which belongs to the typical extreme manufacturing category, it is difficult to test the casting, forging, red sleeve, finishing and system dynamics tests in the crankshaft production process with conventional physical test methods. The finishing of the large marine crankshaft adopts a special crankshaft machine tool with a rotatable center frame. Through finishing, the crankshaft can meet the size, shape and position tolerance requirements of the design drawings, and the crankshaft axis is straight. However, because the crankshaft is very long, the elbows have complex shapes and poor rigidity, and complex b...

AI Technical Summary

Problems solved by technology

[0005] At present, there is no modeling system for crankshafts in the field of finite element modeling. The adjustment and processing technology for crankshaft finishing can only be done manually based on the experience of technicians, which is very random and the production efficiency is very low.
