SolidWorks has grown into a vital tool for engineers and designers who need to bring their ideas into the physical world. For students navigating complex assignments and industry-level design projects, advanced challenges often arise that require both technical depth and creative solutions. At SolidWorks Assignment Help Service, we guide students through these challenges, providing not only support but insight into how real-world engineering problems are solved using SolidWorks.

Below are two sample questions with detailed solutions that reflect the kind of expert assistance we provide at the master’s level. These samples highlight the problem-solving approach adopted by our team and are intended to demonstrate the rigor and depth of our support services.

Question 1: Designing a Parametric Helical Gear with Custom Tooth Profile for Power Transmission

Scenario
You are tasked with designing a parametric helical gear intended for a high-load transmission system. The gear must support variable module sizes and helix angles, and the user must be able to modify parameters for different operational loads. In addition, the gear teeth must feature a non-standard asymmetric profile optimized for one-directional torque transmission.

Solution Approach
To address this problem, the design must be both parametric and robust under changes to inputs such as module size, pressure angle, and helix angle. The solution process involved the following steps:

1. Parametric Modeling with Equations
   A base sketch was created in the front plane for the gear tooth profile, and global variables were assigned for parameters such as:

   • Module

   • Number of teeth

   • Helix angle

   • Pressure angle

   • Addendum and dedendum

   Equations were used to drive sketch dimensions, ensuring the model updates correctly when variables are changed.

2. Tooth Profile Generation Using Curve-Driven Pattern
   Since the tooth shape is asymmetric and non-involute, the profile was sketched manually using spline curves based on mathematical equations for optimized loading. This sketch was revolved to create a single tooth, then patterned along a helical path using Curve Driven Pattern, which considered helix angle and lead distance.

3. Solid Body Creation and Helix Cut
   A helix was created by defining pitch, revolutions, and direction based on the helix angle. The base body was then cut using the swept cut feature to produce the gear profile with an accurate and consistent helical tooth form.

4. Validation and Simulation
   A static analysis was performed using SolidWorks Simulation to evaluate stress distribution under torque loading. The gear was mated with a simplified pinion and torque was applied to validate contact surface behavior.

This problem demonstrated not only the modeling skills required to build a highly customizable part but also the analytical skills necessary to confirm its mechanical viability.

Question 2: Creating a Motion Study of a Dual-Axis Robotic Arm for Precise Pick-and-Place Operations

Scenario
A robotic arm is designed with two rotational joints allowing dual-axis movement. The task is to simulate a complete pick-and-place operation using SolidWorks Motion Study, evaluating the timing, range of motion, and actuator torque required for each joint. The end-effector must reach a designated position within 3 seconds while ensuring smooth acceleration and deceleration profiles.

Solution Approach
This type of simulation blends kinematic modeling with time-based motion planning. Here’s how it was approached:

1. Assembly and Mates
   The robotic arm was built using multiple linkages and rotary joints. Accurate Mate references were defined, especially for the two rotational joints (Revolute Mates), which serve as pivot points for the arm.

2. Defining Motors and Motion Profiles
   In the Motion Study environment:

   • Rotary Motors were assigned to each joint.

   • A Spline-based motion profile was created for smooth start and stop behavior to mimic real-world actuators.

3. Time-Controlled Path Planning
   The motion of the end-effector was constrained to a specific XYZ trajectory using path mates and reference geometry. This allowed the study to simulate a timed sequence that begins at rest, picks up a payload, moves it to a second location, and releases it.

4. Torque Output Evaluation
   After simulating the motion, the motor torque outputs were plotted and compared against actuator limits. These graphs helped confirm whether standard servo motors would suffice or if specialized actuators were needed.

5. Collision Detection and Optimization
   Collision detection was enabled to ensure that the robotic arm wouldn’t hit itself or the environment during motion. Adjustments to joint limits and range of movement were made to improve efficiency and safety.

This study illustrated the integration of design, control, and validation that is essential in robotics and automation-related projects.
