Strength And Stiffness

As an important part of the automobile assembly, automobile frame bears the complex loads from the road and loaded, and be installed car assembly as the carrier, and thus the frame strength and stiffness in the car overall played a very important role in the design. This article use Solid Works to design a frame of a truck, and focus on using the finite element analysis software ANSYS study mechanical analysis and study of the vehicle frame. Here discussed the pure bending conditions and reverse the conditions of static strength, the static stiffness analysis. The analysis showed that the frame of the stress value is less than the ultimate strength of materials to meet the design requirements, but the intensity is too large, so the economy is relatively poor, while considering the local strength of the frame. According to this characteristic of the truck frame, this paper presents a program on the frame lightweight design, the results of optimization makes the weight of frame to reduce, saving raw materials, lowering production costs, improving fuel economy .

The paper discusses the main aspects of soil reinforcement in road construction by adding a binder component to them. The use of this technology allows to solve the problem of high-quality raw materials shortage while improving the physicomechanical characteristics or keeping them at the same level, as well as to increase labor productivity and reduce production costs. The technogenic raw materials for the production of soil concrete were studied, the main physicomechanical characteristics and requirements that must be taken into account when selecting the composition of the soil concrete mixture were analyzed. The paper compares the physicomechanical characteristics of the road composite, reveals the advantages and disadvantages of introducing binder components of various types: cement, cement with modifier and a complex binder. It has been established that the introduction of a complex binder or cement with modifier contributes to the improvement of the physicomechanical characteristics while reducing the consumption of cement in the composition of the soil-concrete mixture compared to traditional soil-concrete with cement.

Frame of the van is the basis for mounting of the other assemblies, by sustaining the various kinds of force and load from the road and the weight, so the strength and stiffness of the frame is the very important on the overall design of the van. This thesis does an analysis and research in accordance with ANSYS, discussing the frames static strength of the warp working status and the torsion working status, and doing an analysis of stiffness. The result of analysis shows that the frames ultimate stress is lower than the ultimate strength of material, satisfy the design demand. But the strength of material is overall higher, so the economic efficiency is low. This thesis is also provided the parameter for the nest step design of stress centralization areas and unreasonable design structure.

The Business Cycle

This chapter covers the economic fundamentals of commodity markets (i.e., what shapes the evolution of the price of raw materials) in three steps. First, it covers the theories explaining why the futures curve can be upward or downward sloping, an essential element for commodity producing companies. The evolution of inventories and hedging pressures are the two dominant sources of explanation. Second, the chapter reviews the fundamentals of commodity spot prices: technologies, supply, demand, and speculation. Production costs draw the long-term evolution of prices, but demand and supply shocks can trigger substantial variations in commodity prices. Third, the chapter presents how commodity prices interact with the business cycle. Commodities are influenced by the world activity but can also have a material impact on it.
