1. Adams 
O Adams View possui 9 tipos de juntas simples e 2 complexas conforme mostrado 
abaixo. Estas mesmas informações você tem através do Manual do Adams ao utilizar o 
software: 
 
 
Figur1 1 – Adams joint types 
 
Adams View possui dois tipos de juntas idealizadas: simple and complex. 
Simple joints - Conecta os corpos diretamente. Incluem os seguintes tipos de juntas : 
 
• • Revolute Joints. See Revolute Joint Tool. 
• • Translational Joints. See Translational Joint Tool. 
• • Cylindrical Joints. See Cylindrical Joint Tool. 
• • Spherical Joints. See Spherical Joint Tool. 
• • Planar Joints. See Planar Joint Tool. 
• • Constant-Velocity Joints. See Constant-Velocity Joint Tool. 
• • Screw Joints. See Screw Joint Tool. 
• • Fixed Joints. See Fixed Joint Tool. 
• • Hooke/Universal Joint. See Hooke/Universal Joint Tool. 
 
Complex joints indirectly connect parts by coupling simple joints. They include: 
• Gears. See Gear Joint Tool. 
• Couplers. See Coupler Joint Tool. 
 
 
É possível utilizar o Easy5 (software da MSC equivalente ao Matlab) para 
complementar o modelo e considerar os efeitos de um mancal fluidodinâmico. 
Aparentemente o mancal não é considerado flexível. 
 
2. HOTINT 
HOTINT is a free software package for modeling, simulation, and optimization of 
mechatronic systems, especially for flexible multibody systems. It comprises solvers for 
static, dynamic, and modal analysis, a modular object-oriented C++ system framework, 
a comprehensive element library, and a graphical user interface with tools for 
visualization and post-processing. 
 
 
Revolute Joint Constrains all 
relative degrees of 
freedom between 
two bodies except 
the rotation about a 
local rotation axis. 
 
Prismatic Joint Constrains all 
relative degrees of 
freedom between 
two bodies except 
the translation along 
a local sliding axis. 
 
Universal Joint 
 
 
Constrains the local 
position of two 
elements and keeps 
two axes, one on 
each body, 
perpendicular to 
each other. 
 
Rigid Joint Constrains the 
position and relative 
angles of an element 
at a specied local 
position 
 
 
Cylindrical Joint 
 
Constrains like the 
RevoluteJoint, but 
allows additionally 
translation along the 
rotational axis

3. MBDyn 
MBDyn features the integrated multidisciplinary simulation of multibody, multiphysics 
systems, including nonlinear mechanics of rigid and flexible bodies (geometrically exact 
& composite-ready beam and shell finite elements, component mode synthesis 
elements, lumped elements) subjected to kinematic constraints, along with smart 
materials, electric networks, active control, hydraulic networks, and essential fixed-wing 
and rotorcraft aerodynamics. 
• Revolute Joints. 
• Translational Joints 
• Cylindrical Joints 
• Spherical Joints 
• Planar Joints 
• Fixed Joints 
• Universal Joint/Cardano 
The MBDyn has a module for hydrodynamic Bearing: 
- Module-fab-sbearings - Hydrodynamic bearing, Rolling bearing 
- Module-hydrodynamic plain bearing with offset - This module implements a 
hydrodynamic plain bearing according to Hans Jurgen Butensch ¨ ¨on 1976 Das 
hydrodynamische zylindrische Gleitlager endlicher Breite unter instation¨arer 
Belastung.
