Robotic leg inverse dynamic modelling and design optimization in Simmechanics
Grepl, Robert ; Kratochvíl, Ctirad
This paper deals with the design of inverse dynamical model of pantographic robotic leg in Matlab - SimMechanics. This problem belongs to the class of dynamical inverse modelling, where the positions ofactuators and efector are defined in different coordinate systems. Therefore we also have to use inverse kinematicsmodel. This inverse dynamic model serves as the base of robotic leg design optimization. The definition of valuefunction is based on known properties of drives and variable parameters of the leg design. Optimization maximizesparameters of efector trajectory.
Inverse kinematic modelling in simmechanics and application for robotics mechanisms
Grepl, Robert ; Ondrůšek, Č.
This paper deals with the design of inverse kinematic model in software Matlab-SimMechanics. Presented approach is applied to particular robotic mechanism, thepanthographical leg of quadruped walking robot. It is possible to use created model as an approximation methodtraining data generator or directly in computation in the Matlab.
On urban atmospheric boundary layer simulation
Aubrun, S. ; Leitl, B. ; Jaňour, Zbyněk
Flow and dispersion inside the urban street canyon simulation was introduced. Urban region is simulated by roughness elements. the main characteristics of the flow are determined by LDA system and optimalisation of the parameters is determined by spires.

Pelikán, Vladimír ; Machová, Anna
The research report presents a new code DynRad3D for simulations of radiation damage by molecular dynamic technique and as well, some new results at 600 K.
Simulation of dynamic phenomenons in nonlinear parametric systems with kinematic coupling and backlash
Škuderová, Alena
For verification analytical results of solving inner dynamics on nonlinear parametric system was built simulation model of stiff bearing external spur gearing, which respects except variable stiffness - given change numbers of tooth in mesh - also influence of geometrical departure evolventy curve from ideal profil side tooth. Simulation model of system with two degrees of freedom covers region of normal mesh, tchnological backlash and areas of inverse mesh.
SBRA method and the development of its application
Půstka, D. ; Marek, Pavel
Tento příspěvek obrací pozornost na potenci l metody SBRA, zvláště u ocelových konstrucí. Plně pravděpodobnostní řešení daného problému je tu ukázáno na dvou příkladech. Na ocelovém nosníku ovlivněném korozí a na akumulaci poškození únavou na ocelových podpěrách namáhaných větrem. 295 This paper turns attention to the potential of the simulation based reliability assessment method SBRA, considering especially the durability assessment of steel structures. A fully probabilistic approach is demonstrated using two examples. A steel component is exposed to time dependent effects of corrosion and assessment of the accumulation fatigue damage.
