Study of Table Tennis Training System

Table Tennis is a sport that everyone likes. But In todays treat time as gold, it is not easy to want to find a time to accompany a beginner; secondly, more and more the people want their table tennis technology higher, but they have no rivals. On this basis, in order to really make the table tennis training completely out of accompanying training, in this paper, the training machine and training system of table tennis have been studied.

Design and Exploration on Automobile Crane Mobile Counterweight Balance

The automobile crane is a crane which is arranged on a common chassis or special automobile chassis, the driving cab and a lifting control room. The advantages of this crane is good mobility, transfer quickly. weight body truck crane is a very important part, but also a key part of the whole balance, its main function is to balance the gravity center of the whole lifting, make more stable, more safety. The current general crane are fixed weight, the weight is directly arranged motionless in the car tail, installation or transportation unloading work. This design is mainly the counterweight body is designed into a movable and rotatable, this mechanism has good flexibility, can adjust the balance weight body position, equivalent to adjust the focus of the counterweight body, enhance the lifting capacity and safety.

Novel Design of Manual Mechanical Rotary Table

Mechanical rotary table [ has been widely used in many work applications, where rotating capacity and power of the table are necessary elements to ensure the operation safety. The paper provides a rotary table design operated by hand movements to lift and fall, rotate and turn over in the absence of electricity and other external powers. Therefore, table should have a simple structure and be easy to maintain, meanwhile working area should be wide enough for convenient operation. Simultaneously good safety performance is of great significant in this design, which requires a reasonable arrangement of each components position to minimize the number of dangerous sections. The rotary part applies commonly used clamping flange, which allows the table to clamp different types of components. Mechanical rotary table can be applied in many different occasions, making it a truly multi-functional workbench.

Design of Sledge Based on the Ergonomics

According to physiological and psychological characteristics of adults, this paper proposed sled design based on ergonomics. The paper respectively provided human research, analysis and design for two aspects directly related to ergonomics, handlebar and seat, in order to make product safer, more comfortable and effective to meet consumers demands.

Study on Problems and Countermeasures in Practice Teaching of Undergraduates in Mechanical Industrial Design Major

Aiming at the problems existing in practice teaching of undergraduates in mechanical industrial design major in college, a series of countermeasures has been raised, like paying more attention to practice teaching, increasing the proportion of practice teaching, innovating the content of practice teaching, adjusting the major curriculum, building a scientific and reasonable team of teachers, and updating the equipments for practice teaching. And on this basis, a summary is given on the problems and countermeasures in practice teaching of undergraduates in mechanical industrial design major.

Waste Money Drilling Environment Control Device Design

This paper expounds the design mechanism and principle of control device work environment for dust pollution control and prevention working condition, in waste money drilling processing. This paper also presents the technological process, the device structure design and work mechanism of the device and lays emphasis on the working principle, the classification and selection of the dust filter; presents the classification comparison and selection, the design and characteristic calculations of gas collecting dome; introduces the design, installing methods, main parameter calculations of the piping system, and the computations and selection of the motor and the fan device as well; presents the classification of bag type filter, the requirement and selection of filter bag, and the calculation of main parameters of dust filter. The design of the device not only increases the waste paper recovery efficiency in the process of disposing waste money and avoids dust pollution, but also contributes to the safety, security and the inspection of disposing procedure.

Structural and Shaping Design of Centerless Cylindrical Grinding Machine Based on CAD

In this paper, according to the requirements of the topic, through the large market research and a series of calculation, I design the requirements of the grinding wheel frame and the spindle. In combination with relevant patent reform on the basis of grinding machine, The guide part of the drive system, micro feeding and automatic feeding mechanism is analyzed and design calculation, so that the machine can greatly reduce the labor intensity of workers and improve the processing accuracy. On this base of the design, I design and select the suitable rail to guarantee the processing precision and the wheel frame seat movement accuracy by using the calculated data and shape dimensions. At last, I design structural and shaping of the centerless cylindrical grinding machine.

Virtual Prototype Design of Remote-Control and Mobile Tea Table

Along with modern science and technology developing quickly, Remote control technology is in our life. The combination of machine and remote control technology is also bringing infinite fascination and convenience to our life. In the paper, remote control technology is applied to furniture-tea table, and making the tea table mobile according to hominine injunction. The whole figure of tea table is to apply motility element-sphere; the motion and swerve of tea table is to imitate structure of motorcar; in order to space saving, the worktable of tea table is to apply contact design.
