Abstract

The invention discloses a grasshopper-based mobile steel guardrail parameterization rapid modeling method, which comprises the following steps of: 1) drawing a mobile steel guardrail standard knot, and drawing a model I by using Rhino according to a mobile steel guardrail design drawing; 2) establishing a simple model, selecting each part of the standard knot of the movable steel guardrail by using a geometric body selection battery of a Rhino system, and keeping initial parameters unchanged to generate the simple model; and (3) rapid modeling is carried out, and for movable steel guardrails with different heights and different anchoring distances, another movable steel guardrail can be generated by changing input parameters. According to the method, manpower resources are effectively saved, operation is simple, the working intensity of workers is reduced, the constraint of production time is broken, and the modeling production efficiency is effectively improved.

Description

Technical field: [0001] The invention relates to a grasshopper-based parameterized rapid modeling method for a mobile steel guardrail, which belongs to the field of computer-aided design and manufacture. Background technique: [0002] In finite element simulation, 3D modeling is the most time-consuming part, and the quality and speed of modeling often determine the efficiency of simulation. Traditionally, computer software such as CAD and 3DMAX is used to model manually. Manual modeling will have a large workload during production, and manual modeling one by one is prone to errors, low efficiency, and will cause redundant workload. . [0003] In the finite element simulation, geometric models with different guardrail heights and different anchoring distances are required, but the basic parameters of the mobile steel guardrail are similar. For the current rhino software traditional modeling method, as long as the model has a different parameter, the model must be built agai...
