In order to further increase the volume, reduce the weight and manufacturing cost, the key structural parameters of thin-walled metal packing container are optimized. The instability conditions under circumferential external pressure and axial load are analyzed, a mathematical model with the constraint of critical instability strength, the maximum volume and minimum mass as the objective is constructed. Multi-objective optimization method with nonlinear constraints is used to solve the key structural parameters, such as wall thickness, diameter and height, and the optimization result is calculated by fgoalattain() function in the Matlab optimization toolbox. The instability pressure test system is constructed, the instability pressure of the optimized thin-wall metal packing container is tested. The results show that the unstable pressure is higher than 120kPa, which are better than the design index.

A kind of multiple parameter data acquisition system was designed based on single-chip microcomputer which can realized the data acquisition of temperature and DC motor speed. The data acquisition system consists of sensor, signal processing circuit, single-chip microcomputer and LED digital tube. The speed signal is acquired by photoelectric sensor, put into the Single-chip microcomputer processed after processed by signal processing circuit, and displayed the value in the digital tubes. The temperature signal is acquired by digital sensor, and the Single-chip microcomputer can read the data directly. Through two independent keyboards, the test system realized the data acquisition and data switch displaying of the multiple parameters.

The Future

Nowadays, various test equipment tend to be more intelligent, the test equipment of the volt-ampere characteristic of CT is so too. As the development of the electronics, VLSI(SCM) is manufactured. The purpose of our project is to scheme out a intelligent test system by the computer technique and the test technique. This equipment is mostly made of the SCM system and the peripheral equipment. We control the output of the digital transformer by SCM. The output voltage can make the TL494 create PWM wave. The wave is the control signal of the main circuit. The output wave of the main circuit is the sine wave, and the value of the output can be amended automatically. Compared with the traditional equipment, this equipment is smaller and use less energy, but its function is more powerful. It can be programmable. We can take it more expediently. So, this kind of equipment can be used widely in the future.
