Description

technical field [0001] The invention relates to a simulation method, in particular to a simulation method and system suitable for calculating the tonality curve of a fishing rod. Background technique [0002] The tonality curve refers to the curved line formed when the fishing rod bears the vertical load at the end. The tonality of a fishing rod can be judged by the tonality curve. At present, the relevant research on tonality curve mainly adopts finite element method and deflection curve control equation solution method, while fishing rod manufacturers mainly rely on fishing rod performance tests to adjust and obtain suitable tonality curves. The analysis and calculation of the finite element method needs to go through a series of fixed processes such as modeling, material property definition and assignment, mesh division, definition of analysis steps, definition of load and boundary conditions, definition of assembly and interaction relationship, etc., which is time-consum...

Problems solved by technology

The analysis and calculation of the finite element method needs to go through a series of fixed processes such as modeling, material property definition and assignment, mesh division, definition of analysis steps, definition of load and boundary conditions, definition of assembly and interaction relationship, etc., which is time-consuming and cumbersome. The requirements for professional skills of designers are also stricter

The test verifies that the curve obtained by the tonality curve method is accurate, but due to the need for fishing rod manufacturing, the mold, design, and material costs are significantly increased, and the obtained tonality curve often cannot quickly meet the design requirements, and repeated iterative tests are required. Great waste of time and manpower and material resources, low efficiency
