Conventionally, the influence of guy wire and wind load on derrick was often ignored in the static strength analysis of derrick of truck-mounted workover rig, it does not accord with the actual working conditions. This paper made the finite element analysis for one derrick of Truck-mounted workover rig through ABAQUS software. The author derive the maximum static hock load which derrick can bear, and reasonably shorten projective radius of guy wire, under different static hock load and wind load, determining the weakest position of derrick. Truck-mounted workover rigs are widely used in the filed of workover and drilling operation, due to their characteristic of power maneuverability and convenient to use. Derrick is the mainly working part of workover rig, as well as the weak links of workover. In order to guarantee relatively high security performance, we should accurately make simulated calculation for carrying capacity of derrick in the process of designing. The author derive the maximum static hock load which derrick can bear, and reasonably shorten projective radius of guy wire, by using the ABAQUS FEM system, apply for statics analysis of derrick under different static hock load and wind load.

The Finite Element Analysis

On the basis of working characters, taking a hydraulic excavator as an example, an integrated and refined finite element model of working mechanism was established. Selected four typical working conditions, the strength analysis was made for the assembled working mechanism. According to the finite element analysis, the structure of the working mechanism was improved. The improved working mechanism met the required strength design after increasing the hydraulic system pressure.The results show that this analysis method of working mechanism can provide reference for the excavator working mechanism design.

Aims The aim of this study is to evaluate the effects of the chincup appliance used in the treatment of Class III malocclusions, not only on the mandible or temporomandibular joint (TMJ) but also on all the craniofacial structures. Materials and Methods Chincup simulation was performed on a three-dimensional finite element (FE) model. 1000 g (500 g per side) force was applied in the direction of chin-condyle head. Nonlinear FE analysis was used as the numerical analysis method. Results By the application of chincup, stresses were distributed not only on TMJ or mandible but also on the circummaxillary sutures and other craniofacial structures. Conclusions Clinical changes obtained by chincup treatment in Class III malocclusions are not limited by only mandible. It was seen that also further structures were affected.

Plastic Shakedown

Shakedown is a cyclic phenomenon, and for its analysis it seems natural to employ a cyclic analysis method. Two problems are associated when this direct approach is used in finite element analysis. Firstly, the analysis typically needs to be stabilized over several cycles, and the analysis of each individual cycle may need a considerable amount of computing time. Secondly, even in cases where a stable cycle is known to exist, the finite element analysis can show a small continuing amount of strain accumulation. For elastic shakedown, non-cyclic analysis methods that use Melan’s theorem have been proposed. The present paper extends non-cyclic lower bound methods to the analysis of plastic shakedown. The proposed method is demonstrated with several example problems.
