5 Analyze the Simulation Module Overview Obtaining analyses data from a simulation is one of the most valuable aspects of using simulation as part of the manufacturing process. The data obtained in these analyses can be captured and generated into reports that feed multiple decision making processes. The power of the PPR architecture is that it permits easy revision of the simulation model based on the outcome of the analyses by permitting direct access to the data through the PPR tree. The value of Dynamic Clash was demonstrated in an earlier module. Now, with the Clash analysis functionality fully engaged, the clash information can be captured and generated into an XML report. Distance and Band analyses provide important information regarding part fit through the measurement of distances and graphical representation of the seed distance between two parts. Sectioning allows the user to" see inside” a slice of the assembly, giving a unique perspective that can sometimes answer some sticky manufacturing questions. This information, is captured and can be reported. With Swept Volume, the total amount of space that is necessary to accomplish a move is visualized. So, while a trajectory of a move may appear to be adequate, swept volume can uncover clues to the physical space necessary that may not be apparent otherwise. In Measure Analysis the model can be queried for specific measurements. Measuring an item, its thickness, and the distance between it and another object, reveals critical information for manufacturing, tooling, human and a variety of other factors. The Gantt Chart allow the user to see the larger picture of the simulation study. It represents the sequence of activities and the impact of time. As with the other functions, modifications made to the process or properties in the Gantt chart are reflected throughout the simulation.

5 Analyze the Simulation About Collision Analysis Conduct Collision Analysis Earlier, Dynamic clash detection was used to get a general idea of the intended moves when creating a simulation. This topic describes how to use Clash Detection when bodies are static and when a move activity is executed. This clash methodology is capable of analyzing the clash situation, capturing the data, and producing reports that assist with project communication. Running the simulation in assembly or disassembly sequence with the stop mode activated will cause the simulation to stop at every occurrence of a clash. This offers an overview of existing conditions. When Clash Checking is activated its parameters can be set to examine interference in a variety of ways. The analysis can be configured as the clash is examined or, a queue can be established ahead of time that forms a list of specific items to be analyzed. When the analysis is configured, the ability to conduct a Bind analysis is activated. Producing XML reports of clash conditions captures the information for discussion and is easily shared in many media forms. More about Clash Detection can be found in the On-Line documentation 6 S E M E T S Y S T L U A S S A D t h g i r y p o C
5 Analyze the Simulation Run the Simulation in Stop mode - Procedure Conduct Collision Analysis Running the simulation with Clash Detection in Stop Mode gives a general picture of the clash locations. 1 Begin running a clash analysis by restoring the initial state of the simulation. By using the Reverse the Process function, the simulation can be evaluated for clash conditions in either assembly or disassembly sequence. 2 From the Simulation Analysis toolbar select the Clash Detection drop down to reveal the Clash Modes Off, On and Stop. Select the Stop mode. This will stop the simulation at every occurrence of a clash. 3 Run the simulation. Use the Process Simulation player to step through the simulation as it stops at each clash. 7 S E M E T S Y S T L U A S S A D t h g i r y p o C
5 Analyze the Simulation Clash Checking - Procedure Conduct Collision Analysis Activating Clash Analysis creates the ability to examine and collect clash data in a variety of ways. 1 Activate Clash Analysis by clicking on the Clash icon in the Simulation Analysis toolbar. 2 The Check Clash dialog box appears. Name the Analysis with some unique identifier then select the type of analysis desired. Contact + Clash Checks for contact as well as any overlapping space. Authorized penetration Checks whether an object penetrates another object beyond a specified amount. Penetration distance is set in the specification box. S E M E T S Y S T L U A S S A D t h g i r y p o C Clearance + Contact + Clash Checks for contact, overlapping space, and invasion of a predefined clearance zone around an object or objects. Clearance values are set in the specification box. Clash rule Checks whether the situation is in conformance with a previously established rule. Specification box Values in this box reflect the Clearance zone or the Penetration depth depending on the type of analysis selected. Inst. Inst. 8
