Abstract


Vertical veneer slicer is the chief equipment of wood manufacture industry. As the accelerated development of wood industry, the development of the xylotomy industry has been driven greatly and the production updates continuously. The design of vertical veneer slicer is maturity and series at present. As a result, it is necessary to advance the design and production efficiency of vertical veneer slicer. so it is very significative to advance the design level and efficiency on the chance improving the company competition.For this reason, this paper is proposed to design a kind of vertical veneer slicer and it’s optimum, which is based on the simulation technique. Firstly, analysis of basic structure and principle of vertical veneer slicer are presented, then investigating the design principle of vertical veneer slicer working device; then studying the dynamic model and dynamic balance of crank slide mechanism, and comparing the plan of working device of vertical veneer slicer according to the traditional way of dynamic balance.Making the working device high speed、high efficiency and smooth operation became the goal of optimum when other function indexes satisfied with the three dimensional modeling software and multi-body dynamic software to the working device vertical veneer slice. The dynamic balancing problem of machinery is one of the important mechanical topics. Generally, this kind of problem is solved by the analytical method. However, the method can be only available to the problem with the simple structure and regular components. And this method also requests that optimization variables and the optimized goals have the explicit analytic equations. But simulation approach can more conveniently solve the problem of dynamical balancing which contains the irregular and complex components. And this kind of problem, the explicit analytic equations can not be easily obtained between the optimized goals and variable.The virtual prototype of vertical veneer slicer was built under the circum stance of the software ADAMS, and the matching blocks of vertical veneer slicer were parameterized. Through optimization analysis, we got the optimal angle and mass, solved effectively the question of motor overheat、lower rotation speed、unstable running during the working of the vertical veneer slicer, realized the high speed and high efficiency goal. This paper introduced the analytical method of solving conventionally dynamic balancing of slider-crank mechanism at the same time. Through comparing, this method of ADAMS is more accurate、more efficient. The result of optimum is up to the request of the manufacturer through production.
