Study And Application Of CAD/CAE Technique On The Electronic Truck Scale Weighing Apparatus

In recent years, with the type of transportation vehicles increase, loading thecontinuous improvement of the ability of the bearing capacity of the truck scale putforward higher request, and truck scale scale platform is the main equipment of carryinggoods, so scale the structural design of the machine is especially important.At present，domestic technology with foreign still have a large gap, moreover thesteel structure of the electronic truck scale structure form is very diversiform, the questionof the study also many, however, most of the reference reference material, found on thetruck scale electronic system this one of the more people to study.To scale a structure, justin the use and maintenance on a concern, structural design just by experience, as well as areference of foreign technology, the most important is to do not have a unified standardsand specifications.This topic by large general finite element analysis software ANSYS, for about acompany SCS series analog electronic truck scale scale the structure of a digital designand analysis.After the digital design and optimization technique system research, aimed at thecompany product design is not standard, lead to high cost, profit decline, the marketcompetitiveness of lower status. Using large general software for this product by finiteelement analysis and structural parameters optimization design, so as to optimize thestructure of the product, can improve the market competitiveness of products. The designmethod of changing the normal, usually the design thought of to design scheme is severalmodified, calculation. Working a lot, and the effect is not very good, the use of advancedCAD/CAE technology, using APDL language establish truck scale scale sets themathematical model of the structure, and then call CAE optimization design module, setthe objective function, the design variables, the state variables, the last through thecomputer by oneself the operation can be concluded that U structure size scale sets thebest combination of, so as to provide reference for the structure improvement.For this topic research, specific do the following aspects of the study:1. Understand the SCS series electronic truck scale scale the structure of the machine andworking principle, and establish the mechanical model;2. SCS series for electronic truck scale scale machine structure, design and the crosssection is inertia formula;3. Use the finite element analysis tools, analyzes the different load conditions in the stressof the situation;4. Using finite element analysis of the module language APDL, established the parametricfinite element model;5. According to the optimization of the mechanical design principle, established themathematical optimization model, and the optimal analysis;Through the above aspects of calculation and analysis, and through the comparison of the experimental test data, this paper puts forward a structure improvement ideas, finallyestablished scales of the machine structure size. Compared with the original scales sets,the quality of the platform scale was reduced by14.7%, and at the same time it also provesthis topic research method of reliability, for engineering problem, of great significance.
