R&L Kinematics of Crank Models in Motor Housing Punch Process

With regards to the assembly line of cost control of Dechang(HK) company, the motor housing’s cost control of process will be necessarily respected. Because the supply quantity is big in a machine the price of motor housing is small, so that the cost control of automatic production line is significant with modeling. It is found that the control of equipment includes in shaft and crank linkage for benefit which also needs to be controlled in detail. For the sake of benefits can we fundamentally resolve the main problem of high cost process

The Relationship between Quality and Efficiency in Business Management

Quality and efficiency are the two most important factors for the survival of an enterprise.Quality is essential, then efficiency.Only the quality in the first place, to ensure the efficiency of the implementation.You can imagine when the first step didn't happen.So in the enterprise management should always put the quality in mind, always inspire the concept of quality.Don't put efficiency in your mouth every day, because it is too snobbish and haste makes waste.So recruit some of the level of people to serve for the enterprise, and reuse it, in order to constantly achieve new things, so that the quality gradually up.And continuous contact with workers, to understand the real content of the product and equipment, so that the quality of the product quality.In addition, the requirements of customers should be discussed quickly and communicated with the production department, so that the product quality can be improved and the cost can be reduced to seek higher prices. The purchase order decides technology which decides quality and efficiency as well. The latter determines goods quality and quantity through equipment by staffs who is capable of the equipment such as machinery design. Another is mould which could be designed too through fit size and material.

Convergence Proving of the Theoretical & True Elongation Inequalities by Derivation and Analogy

According to LNƐ, theoretical & true elongation of tensile, and by adopting the increasing function of formulas with the derivation and analogy methods, the elongation formula of 01 and 0 LNε are deduced if ε>1 and 01 and 0<ε<1

Modeling of Economic Cost Distribution in Screw Thread

The screw threading produce is a important process course. The economics modeling is established in this paper so this process will be investigated. In this paper modeling of process is analyzed. The Q and cost decreases with the increasing quantity while the same turn as  AC>AFC>MC is found. AC and AFC is main factors to affect quantity then MC do. It fits to concept of them well. The cost AC and AFC is higher upon L=4 than L=6 while MC is higher upon L=6 than L=4. Meantime the TC and VC is higher upon L=6 than that upon L=4, is the near parallel line. The TC>VC is turn to affect cost. There is a difference for them. TC and VC is main effective costs to compare with AC ˎAFC & MC. The TC and VC become bigger upon K=5 than K=7

A Retrospective Study of Product Quality

Quality is a product to the customer after the test and use of the performance of the product in the index.If there is no problem, it is considered to be a product with good performance; if there is a problem, it becomes a product with poor performance. When a certain number of products have no quality problem after the experiment and operation, it is a good product. However, the evaluation of the use of the assembly after a certain period of time after the final customer should also be discussed. Only in this way can the product quality be improved fundamentally. A/ S is a significant process when the retrospective production is done for its quality to be investigated. Retrospection becomes a new way to study and innovate manufacturer quality currently in busyness. In modern society the retrospect as A/S is more and more prevail at shopping mall in big city for customer convenient application. In terms of their rapid and good mending the excellent brand will be established for product quality yearby-year

The Simulation on Dynamic of Rotary Inertia and Engine’s Inflamer in Light Vehicle

 According to formula we can simulate their driven force and acceleration. The mechanical formula is used to obtain dynamics is used to simulate. The driven force increases when torque increases and tire diameter decreases. We need torque to increase so this is our plan. Acceleration raises when torque raises and it reduces when its weight raises. With the decreasing of radius of road the centripetal acceleration is increasing in the condition of light vehicle. It is that it decreases sluggishly before 0.35m/s2 then it maintains a steep decline to 0.62m/s2 and at last becomes sluggish again. It is valued that the economical efficiency about consumed fuel under different power. In the time of 0.2hr the fuel inflamer inclines sharply first then turns stable. It is the smallest value. Beyond it the fuel maintains a high value all the time. The discharged pollution gas decreases with the decreasing initial temperature. The low initial temperature is good to fuel gas. Meantime the smallest incline range is 300~350K which explains that it is the most save one

Technological Analysis on Motor Stall and Its Perspective

The brush lock is due to assembly tightly during assembling three gripper so that it curls after some time in motor and bare motors. The motor happen to have current decreasing and cause rotary too slowly is an important technique problem. At last the motor hasn’t worked due to disconnection. It give company to bring assembly issue for customers. So the motor stall is main issue in motor working. We shall pay more attention to it necessarily and shall be strict quality inspection and we shall monitor the flow line for the sake of decreasing it. We shall solve the problem as soon as possible and communicate with the customer engineers. Unloaded rotation is radical in the base inspection. The engineer need to negotiate with supplying engineers for the qualified material of brush. Increasing inspection into more times is a method to decrease unqualified brushes. Some experiment method is explained to analyze for customer engineers. Two kinds of motors ie. stepping and asynchronous motor and motors used in future in car is explained to further knowledge to motor’s application. Such as the experiment with torque, voice and electric voltage converter. The pseudo soldering results the slow rotary. The reverse voltage is a reason for a motor to slow rotary even stall

A new study on the superplasticity of TiAl alloys

The superplasticity of Ti-46.7Al-2.2Cr(at.%) alloy was studied by mathematical induction. It is found that Zener Hollomon relative formula and there are serious deflections. According to the true superplastic stress and true strain curves, the deflection values of n=-7.46 and B=1439MPa are obtained, indicating that the limit of n>0 has been exceeded, which needs to be characterized by a negative sign. This shows that it conforms to the principle that the smaller n is, the better superplasticity is, but the problem that it has become a negative number needs to attract the attention of peers meantime B is a better match.

The Study on Simulation of Resistance in Stall Motor

The stall phenomenon which happens in loaded motor is unqualification in application. Meanwhile it may measure the maximum property of motor in manufacture. So the phenomenon is analyzed to find a simulation of electrical state to predict the maximum currency and torque which is a necessary method to be proceeded up to now before design.We find that the simulation fits well to the reference. The conditions of t=6s,U=12V result in the biggest stall force according to rotation to change time and voltage. Then it is t=8s,U=10V; t=10s,U=8V and t=12s,U=6V in turns. As for torque it is t=6s,U=12V;t=8s,U=10V;t=6s,U=12V and t=12s,U=6V in truns
