Seat ring parameterization design method based on simulation analysis

Abstract

The invention relates to a seat ring parameterization design method based on simulation analysis. The seat ring parameterization design method comprises the following steps: constructing a seat ring three-dimensional model; generating a human body three-dimensional model; assembling the seat ring three-dimensional model and the human body three-dimensional model; establishing a human body-seat ring finite element analysis model through mesh generation and by applying a load, an initial condition and a boundary condition; solving the human body-seat ring finite element analysis model through CAE analysis software, and extracting evaluation data; performing comfort evaluation according to the extracted evaluation data; outputting a final design scheme of the race. The invention provides theseat ring parameterization design method by means of simulation analysis. A seat ring structure can be optimized, the seat ring product conforming to human-machine ergonomics can be designed in a high-quality mode, the design period is short, the efficiency is high, the frequency and the cost of product testing and modifying links are further reduced, rapid development and rapid market putting ofthe seat ring product are guaranteed, and the product competitiveness is improved.

Description

technical field [0001] The invention relates to the field of seat ring design, in particular to a parametric design method for seat rings based on simulation analysis. Background technique [0002] With the improvement of living standards, people's requirements for the comfort of toilet products are getting higher and higher, but the existing seat design process lacks quantitative data to measure the rationality of the design scheme, so the final design scheme is difficult Guarantee its real good comfort. When the design is unreasonable, the seat ring will compress the nerves of the buttocks and thighs. When the toilet is long, it is easy to cause insufficient blood supply to the lower limbs, numbness, swelling and other discomfort, which brings a lot of troubles to people. Therefore, providing a parametric design method of the seat ring by means of simulation analysis, optimizing the seat ring structure, making the seat ring structure conform to ergonomics, and improving t...
