“Mars Science Laboratory”
|
Ms. Kendra Short is the manager of the Mechanical Systems Division at the Jet Propulsion Laboratory. She has been at JPL for over 20 years starting as a mechanical hardware engineer and has worked on the Cassini, Mars Pathfinder, and Shuttle Radar Topography Mission (SRTM) programs. More recently she has held several organizational and project management roles. She earned a BS in Mechanical & Aerospace Engineering from Princeton University in 1989 and an MS in Aero/Astro from Stanford University in 1992. Kendra will discuss the Mars Science Laboratory mission, which is NASA’s next generation rover to explore the surface of Mars and is scheduled for launch in 2011. The vehicle design is driven by an entwined combination of geometry constraints, complex and varied loading events and environmental extremes. Her talk will address many of the challenges and their solutions through the application of analysis and simulation software. We hope you will be able to attend the conference to see this and other great presentations. Online conference registration is available at http://event.plmworld.org/. |

Research on the Simulation of the Driving System of a Crawler Bulldozer
Zhang Yaojuan, Cheng Kai, Zuo Peng, Wang Zhilin, Transportation, Mechanical, and Electrical Engineering (TMEE) International Conference, Changchun, 2011, pp. 703-706.
Abstract
The multibody dynamics model of a crawler bulldozer is established in this paper using tracked vehicles’ subsystem Track (LM) of multibody dynamics simulation software RecurDyn, and the simulation analysis of driving system performance is carried out. In the process of simulation, this paper focuses on the analysis of the road wheel’s force, driving wheel’s force and crawler tension in the process of operation in two kind pavement of the clay and hard. Then, the improvement measures have been put forward that the driving wheels had better use shock absorber and the strength and stiffness of track shoe pin should be increased. The simulation analysis result provides reference for the structure optimization design of crawler bulldozer and how to extend the service life of the crawler driving system.
How Multibody Dynamics Simulation Technology is Used
Construction vehicle dynamics can be quickly modelled using RecurDyn’s Track (LM) toolkit. Individual sections of the system can be easily modified within the model to efficiently improve the design of the tracked vehicle. The ground module in RecurDyn is used to simulate both clay and hard pavement. Dynamic simulations were able to show that a shock absorber was necessary and the stiffness of the track shoe pin should be increased.

Analysis and Research of Automotive Trapezoid Synchronous Belt’s Fatigue Life
Li Zhanguo, Jiang Ming, Li Jiaxing, International Conference on Computer, Mechatronics, Control and Electronic Engineering (CMCE), Chungchun, August 2010, Volume 2, pp 193-195.
AbstractThe dynamic simulation model of synchronous belt meshing transmission is established in dynamics software “RecurDyn” applying the theory of MFBD (Multi-Flexible Body Dynamics), which analyzed the contact force on the working surfaces and stress distribution during the meshing transmission. The Finite Element Analysis Method was used to make the synchronous belt model meshed in Femap and investigated the belt’s teeth stress distribution after the model was imported into RecurDyn. A new design of synchronous belt’s and pulley’s tooth profiles for improving the transmission capacity of the automotive synchronous belt was proposed, in order to discover better materials to increase the fatigue life of the belt by optimization of the geometry of tooth profiles. How Multibody Dynamics Simulation Technology is UsedRecurDyn was used to simulate a timing belt as a flexible body. The stress distribution of the belt is obtained during typical operating conditions. New designs and materials for the belt could be easily tested in RecurDyn to find the optimal design more quickly.

Abstract
For advanced electron beam lithography systems, a simulation tool for a two-axis nano stage is developed in this paper. The stage is equipped with piezo-actuators and flexure guides. Even if piezo-actuators are believed to be feasible for realizing nano scale motions, it is difficult to predict their characteristics due to their nonlinearities such as hysteresis and creep. In this paper, the nonlinear properties are modeled considering the input conditions. In detail, the hysteresis is described as a first order differential equation with 24 sets of the hysteresis parameters and the creep is modeled as a time-dependent logarithmic function with two sets of creep parameters. The characteristics of the flexure guides are analyzed using the finite element method and are embodied into a multi-body-dynamics simulation tool. The dynamic behavior of the simulation tool is compared with the experimental data.
How Multibody Dynamics Simulation Technology is Used
RecurDyn is used to simulate two-axis nano stages equipped with piezo-actuators and flexure guides. Modal data is obtained using ANSYS and then interfaced with RecurDyn. The accuracy was verified using experimental data. This verified model can now be used to test design improvements in rapid succession.
