This article introduces the modeling conditions and the results obtained using AnyBody. The assist suit was worn by subjects, and movements involving tasks that impose a burden on the lower back, such as moving a water storage case and shoveling snow, were measured using a motion capture system. Using the musculoskeletal analysis and modeling functions of the AnyBody Modeling System, a model was created to evaluate the impact of the assist suit on the human body, taking into account data such as suit mass, forces acting on the thighs, and human movements.

In this article, we introduce a case study that explores seating postures using HyperStudy, with the joint angles of the AnyBody human model as parameters, aiming to minimize muscle strain. We present and compare the results of the exploration conducted for each reclining angle. In particular, during the design and prototyping process, it is necessary to uniquely determine the posture during product use based on some rationale, without relying solely on measurements. Here, in several scenes corresponding to different reclining angles, we determined the "comfortable (non-straining) posture for the human body" using the optimization software 'HyperStudy'.

This article introduces a case study using AI-based 3D posture estimation data obtained solely from videos shot with a general digital camera to perform musculoskeletal analysis with Anybody. At our Terabyte Lab, we conducted a lifting motion with heavy objects. Simultaneously, while filming the video with a digital camera, we also collected marker data using our Vicon system for comparative validation. As a result, although the movements during transportation were unfortunately defined as unnatural, the joint compressive forces occurring between the lumbar vertebrae showed almost the same results.

• Mechanism Analysis

In AnyBody, the "soft constraint" option resolves motion analysis, and the concept of "virtual muscles" through the extension of the muscle distribution algorithm addresses the dynamics problems of redundant systems. In this article, we introduce a case study of analyzing "ladder climbing," where a closed state is continuously maintained. This analysis focuses on the subject's movements as they skillfully use both hands and feet to climb the ladder. In AnyBody, the ON-OFF switching of the "virtual muscles" that connect the person and the ladder occurs at the timing when both hands and feet engage with or detach from the ladder. Furthermore, for example, the distribution can be smoothly adjusted based on the degree of contact (horizontal axis).

On March 31, 2017, the Ministry of Economy, Trade and Industry published standard models and guidelines for automotive MBD (Model-Based Development). This document summarizes the contents of a study group focused on 1D simulation, which has been working since October 2016 to promote a development method that conducts advanced development and performance evaluation of automobiles through virtual simulation, in collaboration with automobile manufacturers and parts manufacturers. An update was made in March 2020, adding two new models—a thermal model and a vehicle vibration model—to the existing motion performance model. This article introduces a case study linking the vehicle vibration model to AnyBody.

• Mechanism Analysis

This article presents a case study analyzing the effects on the body when simulating a cylindrical water bag filled with 5 kg (5 liters) of water, assuming a left and right rotational movement in front of the chest. In this case study, we conducted musculoskeletal analysis using AnyBody, taking into account the complex movement of water at that time, and investigated the load on the trunk and upper limbs. For comparison, we also examined how the load on the human body differs between liquids and solids. As a result, it was found that in the case of liquids, the load variations fluctuate randomly compared to solids. Furthermore, even with the same weight and similar movements, the load on the body changes depending on whether the object being handled is a fluid or a solid.
