Implementation of Self Contact in Path Generating Compliant Mechanisms
2016Path generating compliant mechanisms with self contact are synthesized using continuum discretization and negative circular masks. Hexagonal cells are employed to represent the design space and negative circular masks are used to remove material beneath them.

Determination of the effective path of contact of undercut involute gear teeth
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2004An approximate equation for accurate determination of the inner point of the involute profile of undercut spur and helical gear teeth is presented. This point may have influence on the effective path of contact and consequently on the contact ratio, the length of the path of contact and the stress levels, which should be taken into account for ...

International Journal of Precision Engineering and Manufacturing, 2018
An internal helical gear pair with point contact pattern based on the space meshing theory is proposed which consists of an involute internal gear and a pinion with quadratic curve profile. Particularly, the contact path of the tooth surface is selectable, which can inherit the characteristic of the surface.

A Literature Review on Path Planning of Polyhedrons with Rolling Contact
2019 4th International Conference on Control, Robotics and Cybernetics (CRC), 2019Path planning of polyhedrons by rolling on edges includes arbitrary relocation, obstacle avoidance and goal achievement. These tasks have various applications in robotics fields such as autonomous vehicles, navigation and robotic surgery. This paper reviewed path planning approaches applied to rolling contact with different types of polyhedral parts ...

On Regularization of the Convergence Path for the Implicit Solution of Contact Problems
2011Following up to a previous investigation, this paper proposes a strategy to deal with frictionless contact problems involving large penetrations, in the context of the node-to-segment formulation and of the penalty method. The rationale is based on two main considerations: the first one is that, within an iteration scheme, the use of consistent ...

Optimum path synthesis of a four-link mechanism with rolling contacts
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011Kinematic synthesis problems of a four-link mechanism with rolling contacts have been studied in the literature. One may imagine a very difficult synthesis problem, which is much more difficult to solve for a seven-target-point problem. In fact, the kinematic synthesis formulation for a four-link mechanism with rolling contacts discussed in the ...
