Abstract

The invention belongs to the technical field of robots, and particularly relates to a stress analysis method for an indoor fire fighting robot support, which comprises the following steps of: 1, converting each rod piece from an entity into a beam unit, and carrying out grid division; 2, after conversion, a simulation model of the support is built in statics analysis software; 3, taking the stress condition of the typical working condition as input, and performing ansys simulation to obtain stress analysis diagrams and deformation diagrams of different design schemes; the indoor fire fighting robot support is reasonable in structure, the stress condition of the indoor fire fighting robot support is analyzed through statics, multiple schemes are comprehensively compared, a support design scheme better in relative performance can be obtained from the initial stage of design, and a large number of secondary designs caused by unreasonable early-stage model selection in a subsequent durability test are avoided.

Description

technical field

[0001] The invention relates to the technical field of robots, in particular to a force analysis method of an indoor fire-fighting robot bracket. Background technique

[0002] In order to solve the problem that the existing fire-fighting robots are difficult to function indoors, a special fire-fighting robot for indoor use should be designed, which should have the characteristics of small size and sensitive action. To put out fire, this requires the indoor fire fighting robot to install a high temperature-resistant and lightweight fixed bracket to match the fixation and installation of fire extinguishers and related equipment. At the same time, the bracket should have good mechanical properties and can provide sufficient strength and rigidity to resist the shock and vibration encountered by the fire-fighting robot during driving. However, the current domestic selection of pipe racks is mainly based on the comparison and analysis of similar loads based on exp...
