Automatic processing system based on static rigidity of vehicle body and chassis mounting point

Abstract

The invention provides an automatic processing system based on static rigidity of a vehicle body and chassis mounting point. The automatic processing system is characterized by comprising a MuleCar road spectrum acquisition unit, a load input unit, a load conversion unit, a node defining unit, a working condition defining unit, a CAE (Computer Aided Engineering) simulation analysis and calculation unit, a result automatic processing unit and a comparing unit, wherein an output end of the MuleCar road spectrum acquisition unit is connected with an input end of the load conversion unit through the load input unit; the input end of the load conversion unit is further connected with a finite element mesh model; the output end of the load conversion unit is connected with the input end of the result automatic processing unit through the node defining unit, the working condition defining unit and the CAE simulation analysis and calculation unit in sequence; and the output end of the result automatic processing unit is connected with the comparing unit. The automatic processing system has the advantages of simple framework, convenience and rapidness in utilization, low maintenance cost, low fault rate and the like.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an automatic processing system based on the static stiffness of the body chassis mounting point. Background technique [0002] The body refers to the part of the vehicle used to carry people and load goods, and also refers to the whole vehicle. The body of some vehicles is not only the driver's workplace, but also a place to accommodate passengers and goods. The body includes windows, doors, cockpit, passenger compartment, engine compartment and luggage compartment, etc. Chassis refers to the combination of the transmission system, driving system, steering system and braking system on the car. It supports and installs the car engine and its components and assemblies to form the overall shape of the car, bear the power of the engine, and ensure normal driving. . [0003] The body-chassis mounting point is a key part of the connection between the chassis and the body. Si...

Problems solved by technology

Since there are 14 / 16 / 1 eight mounting points on the body-chassis of a general vehicle, and each mounting point bears loads in six directions, and the analysis conditions reach more than 100, the following problems exist in manual processing: there are many mounting points , manually setting the load is prone to errors, and more working conditions increase the workload and increase the modeling time
