查询词典 spot welding

Taking a heavy truck cab as the example, a model of the spotweld space based on finite element was built to analyse the torsional stiffness of the model, and the amount and layout of the spotweld using the discrete variable topology optimization were optimized. Comparing with the original model in welding spot's number and the torsional stiffness, the optimized model has less number of welding spot, but the torsional stiffness of the two model is almost the same.

The chinese character menu under the graphics model is adopted as a interface which communicates the operator to the master computer. The C language is used to program the data system and the operating system. All the welding parameters are stored in the database of the master computer and those welding parameters which are frequently used are defined beforehand, furthermore the selectable extent of each welding parameter is given according to the variers welding technology. Mouse can input and change all the data and the welding order. In order to control the welding parameter on the spot in real-time, the remotely controller is designed.
