Hello everyone,
I’m excited to share our work on the modelling and simulation of a Tower Crane, conducted by @NW and @KC. Here’s a concise overview of our workflow, highlighting the tools and processes we used:
Workflow Overview:
1. 3D Modeling:
- We created detailed 3D models of each component using 3DExperience CATIA:
- Part Design App for individual components.
- Assembly Design/Mechanical Systems Design App for assembling the crane.
2. Dynamic Simulation:
- Using the assembled model, we employed the Motion Analysis App to create mechanisms and perform dynamic simulations, analyzing the crane's movement and interactions.
3. Structural Analysis:
- To analyze the structural integrity of the hoist:
- We used the ‘transfer loads’ command from Motion Analysis to generate a simulation object that includes load data.
- This object is compatible with structural analysis apps like Structural Model Creation and Mechanical Scenario Creation, where we finalized couplings and computed structural simulations.
4. Cable Modeling:
- Since the Motion Analysis app currently lacks the capability to simulate cables:
- We utilized Simpack to model the cable elements.
- We exported our assembly from 3DExperience to Simpack using the connector, which converts the model into a format compatible with Simpack, complete with mass and inertia data.
5. Enhancing the Simpack Model:
- In Simpack, we extended the model to include:
- Pulleys for cable support.
- Connections and excitations to represent motors.
- The cable element itself.
- This allowed us to simulate the full behavior of the Tower Crane, including cable dynamics. We reviewed results and animations within Simpack to analyze crane performance.

We’ve attached a PowerPoint presentation and a video that provide a more detailed explanation of our workflow and findings.
