Try this

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$parent_pro = $objectManager->create('Magento\Catalog\Model\Product')->load($productId); 
$_children = $parent_pro->getTypeInstance(true)->getAssociatedProducts($parent_pro);
foreach ($_children as $child) {
       if ($child->getId() != $parent_pro->getId()) {
        echo "child Id ".$child->getID();
